- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-  \brief  Envelope calculation  
-
-  The envelope adjustor compares the energies present in the transposed
-  highband to the reference energies conveyed with the bitstream.
-  The highband is amplified (sometimes) or attenuated (mostly) to the
-  desired level.
-
-  The spectral shape of the reference energies can be changed several times per
-  frame if necessary. Each set of energy values corresponding to a certain range
-  in time will be called an <em>envelope</em> here.
-  The bitstream supports several frequency scales and two resolutions. Normally,
-  one or more QMF-subbands are grouped to one SBR-band. An envelope contains
-  reference energies for each SBR-band.
-  In addition to the energy envelopes, noise envelopes are transmitted that
-  define the ratio of energy which is generated by adding noise instead of
-  transposing the lowband. The noise envelopes are given in a coarser time
-  and frequency resolution.
-  If a signal contains strong tonal components, synthetic sines can be
-  generated in individual SBR bands.
-
-  An overlap buffer of 6 QMF-timeslots is used to allow a more
-  flexible alignment of the envelopes in time that is not restricted to the
-  core codec's frame borders.
-  Therefore the envelope adjustor has access to the spectral data of the
-  current frame as well as the last 6 QMF-timeslots of the previous frame.
-  However, in average only the data of 1 frame is being processed as
-  the adjustor is called once per frame.
-
-  Depending on the frequency range set in the bitstream, only QMF-subbands between
-  <em>lowSubband</em> and <em>highSubband</em> are adjusted.
-
-  Scaling of spectral data to maximize SNR (see #QMF_SCALE_FACTOR) as well as a special Mantissa-Exponent format
-  ( see  calculateSbrEnvelope() ) are being used. The main entry point for this modules is calculateSbrEnvelope().

-  \brief  Apply spectral envelope to subband samples
-
-  This function is called from sbr_dec.cpp in each frame.
-
-  To enhance accuracy and due to the usage of tables for squareroots and
-  inverse, some calculations are performed with the operands being split
-  into mantissa and exponent. The variable names in the source code carry
-  the suffixes <em>_m</em> and  <em>_e</em> respectively. The control data
-  in #hFrameData containts envelope data which is represented by this format but
-  stored in single words. (See requantizeEnvelopeData() for details). This data
-  is unpacked within calculateSbrEnvelope() to follow the described suffix convention.
-
-  The actual value (comparable to the corresponding float-variable in the
-  research-implementation) of a mantissa/exponent-pair can be calculated as
-
-  \f$ value = value\_m * 2^{value\_e} \f$
-
-  All energies and noise levels decoded from the bitstream suit for an
-  original signal magnitude of \f$\pm 32768 \f$ rather than \f$ \pm 1\f$. Therefore,
-  the scale factor <em>hb_scale</em> passed into this function will be converted
-  to an 'input exponent' (#input_e), which fits the internal representation.
-
-  Before the actual processing, an exponent #adj_e for resulting adjusted
-  samples is derived from the maximum reference energy.
-
-  Then, for each envelope, the following steps are performed:
-
-  \li Calculate energy in the signal to be adjusted. Depending on the the value of
-      #interpolFreq (interpolation mode), this is either done seperately
-      for each QMF-subband or for each SBR-band.
-      The resulting energies are stored in #nrgEst_m[#MAX_FREQ_COEFFS] (mantissas)
-      and #nrgEst_e[#MAX_FREQ_COEFFS] (exponents).
-  \li Calculate gain and noise level for each subband:<br>
-      \f$ gain  = \sqrt{ \frac{nrgRef}{nrgEst} \cdot (1 - noiseRatio) }
-          \hspace{2cm}
-          noise = \sqrt{ nrgRef \cdot noiseRatio }
-      \f$<br>
-      where <em>noiseRatio</em> and <em>nrgRef</em> are extracted from the
-      bitstream and <em>nrgEst</em> is the subband energy before adjustment.
-      The resulting gains are stored in #nrgGain_m[#MAX_FREQ_COEFFS]
-      (mantissas) and #nrgGain_e[#MAX_FREQ_COEFFS] (exponents), the noise levels
-      are stored in #noiseLevel_m[#MAX_FREQ_COEFFS] and #noiseLevel_e[#MAX_FREQ_COEFFS]
-      (exponents).
-      The sine levels are stored in #nrgSine_m[#MAX_FREQ_COEFFS]
-      and #nrgSine_e[#MAX_FREQ_COEFFS].
-  \li Noise limiting: The gain for each subband is limited both absolutely
-      and relatively compared to the total gain over all subbands.
-  \li Boost gain: Calculate and apply boost factor for each limiter band
-      in order to compensate for the energy loss imposed by the limiting.
-  \li Apply gains and add noise: The gains and noise levels are applied
-      to all timeslots of the current envelope. A short FIR-filter (length 4
-      QMF-timeslots) can be used to smooth the sudden change at the envelope borders.
-      Each complex subband sample of the current timeslot is multiplied by the
-      smoothed gain, then random noise with the calculated level is added.
-
-  \note
-  To reduce the stack size, some of the local arrays could be located within
-  the time output buffer. Of the 512 samples temporarily available there,
-  about half the size is already used by #SBR_FRAME_DATA. A pointer to the
-  remaining free memory could be supplied by an additional argument to calculateSbrEnvelope()
-  in sbr_dec:
-
-  \par
-  \code
-    calculateSbrEnvelope (&hSbrDec->sbrScaleFactor,
-                          &hSbrDec->SbrCalculateEnvelope,
-                          hHeaderData,
-                          hFrameData,
-                          QmfBufferReal,
-                          QmfBufferImag,
-                          timeOutPtr + sizeof(SBR_FRAME_DATA)/sizeof(Float) + 1);
-  \endcode
-
-  \par
-  Within calculateSbrEnvelope(), some pointers could be defined instead of the arrays
-  #nrgRef_m, #nrgRef_e, #nrgEst_m, #nrgEst_e, #noiseLevel_m:
-
-  \par
-  \code
-    fract*        nrgRef_m = timeOutPtr;

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-

-  \brief  Envelope extraction  
-  The functions provided by this module are mostly called by applySBR(). After it is
-  determined that there is valid SBR data, sbrGetHeaderData() might be called if the current
-  SBR data contains an \ref SBR_HEADER_ELEMENT as opposed to a \ref SBR_STANDARD_ELEMENT. This function
-  may return various error codes as defined in #SBR_HEADER_STATUS . Most importantly it returns HEADER_RESET when decoder
-  settings need to be recalculated according to the SBR specifications. In that case applySBR()
-  will initiatite the required re-configuration.
-
-  The header data is stored in a #SBR_HEADER_DATA structure.
-
-  The actual SBR data for the current frame is decoded into SBR_FRAME_DATA stuctures by sbrGetChannelPairElement()
-  [for stereo streams] and sbrGetSingleChannelElement() [for mono streams]. There is no fractional arithmetic involved.
-
-  Once the information is extracted, the data needs to be further prepared before the actual decoding process.
-  This is done in decodeSbrData().
-
-  \sa Description of buffer management in applySBR(). \ref documentationOverview
-
-  <h1>About the SBR data format:</h1>
-
-  Each frame includes SBR data (side chain information), and can be either the \ref SBR_HEADER_ELEMENT or the \ref SBR_STANDARD_ELEMENT.
-  Parts of the data can be protected by a CRC checksum.
-
-  \anchor SBR_HEADER_ELEMENT <h2>The SBR_HEADER_ELEMENT</h2>
-
-  The SBR_HEADER_ELEMENT can be transmitted with every frame, however, it typically is send every second or so. It contains fundamental
-  information such as SBR sampling frequency and frequency range as well as control signals that do not require frequent changes. It also
-  includes the \ref SBR_STANDARD_ELEMENT.
-
-  Depending on the changes between the information in a current SBR_HEADER_ELEMENT and the previous SBR_HEADER_ELEMENT, the SBR decoder might need
-  to be reset and reconfigured (e.g. new tables need to be calculated).
-
-  \anchor SBR_STANDARD_ELEMENT <h2>The SBR_STANDARD_ELEMENT</h2>
-
-  This data can be subdivided into "side info" and "raw data", where side info is defined as signals needed to decode the raw data
-  and some decoder tuning signals. Raw data is referred to as PCM and Huffman coded envelope and noise floor estimates. The side info also
-  includes information about the time-frequency grid for the current frame.

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-your modifications thereto in source code form.
-
-You must retain the complete text of this software license in the documentation and/or other materials
-provided with redistributions of the FDK AAC Codec or your modifications thereto in binary form.
-You must make available free of charge copies of the complete source code of the FDK AAC Codec and your
-modifications thereto to recipients of copies in binary form.
-
-The name of Fraunhofer may not be used to endorse or promote products derived from this library without
-prior written permission.
-
-You may not charge copyright license fees for anyone to use, copy or distribute the FDK AAC Codec
-software or your modifications thereto.
-
-Your modified versions of the FDK AAC Codec must carry prominent notices stating that you changed the software
-and the date of any change. For modified versions of the FDK AAC Codec, the term
-"Fraunhofer FDK AAC Codec Library for Android" must be replaced by the term
-"Third-Party Modified Version of the Fraunhofer FDK AAC Codec Library for Android."

-  \brief  Low Power Profile Transposer,  
-  This module provides the transposer. The main entry point is lppTransposer(). The function generates
-  high frequency content by copying data from the low band (provided by core codec) into the high band.
-  This process is also referred to as "patching". The function also implements spectral whitening by means of
-  inverse filtering based on LPC coefficients.
-
-  Together with the QMF filterbank the transposer can be tested using a supplied test program. See main_audio.cpp for details.
-  This module does use fractional arithmetic and the accuracy of the computations has an impact on the overall sound quality.
-  The module also needs to take into account the different scaling of spectral data.

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-  s_k(n) and d_k(n) for n = n[e]+1... n_[e+1]. n[e] represents the start position for
-  envelope e. The border positions n[e] are handled in DecodePS().
-
-  The stereo sub subband signals are constructed as:
-  <pre>
-  l_k(n) = H11(k,n) s_k(n) + H21(k,n) d_k(n)

-  In order to obtain the matrices H11(k,n)... H22 (k,n), the vectors h11(b)... h22(b) need to
-  be calculated first (b: parameter index). Depending on ICC mode either mixing procedure R_a

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-your modifications thereto in source code form.
-
-You must retain the complete text of this software license in the documentation and/or other materials

-You must make available free of charge copies of the complete source code of the FDK AAC Codec and your
-modifications thereto to recipients of copies in binary form.
-
-The name of Fraunhofer may not be used to endorse or promote products derived from this library without
-prior written permission.
-
-You may not charge copyright license fees for anyone to use, copy or distribute the FDK AAC Codec
-software or your modifications thereto.
-
-Your modified versions of the FDK AAC Codec must carry prominent notices stating that you changed the software
-and the date of any change. For modified versions of the FDK AAC Codec, the term
-"Fraunhofer FDK AAC Codec Library for Android" must be replaced by the term
-"Third-Party Modified Version of the Fraunhofer FDK AAC Codec Library for Android."

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-your modifications thereto in source code form.
-
-You must retain the complete text of this software license in the documentation and/or other materials
-provided with redistributions of the FDK AAC Codec or your modifications thereto in binary form.
-You must make available free of charge copies of the complete source code of the FDK AAC Codec and your
-modifications thereto to recipients of copies in binary form.
-
-The name of Fraunhofer may not be used to endorse or promote products derived from this library without
-prior written permission.
-
-You may not charge copyright license fees for anyone to use, copy or distribute the FDK AAC Codec
-software or your modifications thereto.
-
-Your modified versions of the FDK AAC Codec must carry prominent notices stating that you changed the software
-and the date of any change. For modified versions of the FDK AAC Codec, the term
-"Fraunhofer FDK AAC Codec Library for Android" must be replaced by the term
-"Third-Party Modified Version of the Fraunhofer FDK AAC Codec Library for Android."

-ARE GRANTED BY THIS SOFTWARE LICENSE. Fraunhofer provides no warranty of patent non-infringement with
-respect to this software.

-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual

-
-  Besides the filter states of the QMF filter bank and the LPC-states of
-  the LPP-Transposer, processing is mainly based on four buffers:
-  #timeIn, #timeOut, #WorkBuffer2 and #OverlapBuffer. The #WorkBuffer2
-  is reused for all channels and might be used by the core decoder, a
-  static overlap buffer is required for each channel. Du to in-place
-  processing, #timeIn and #timeOut point to identical locations.
-
-  The spectral data is organized in so-called slots, each slot
-  containing 64 bands of complex data. The number of slots per frame is
-  dependend on the frame size. For mp3PRO, there are 18 slots per frame
-  and 6 slots per #OverlapBuffer. It is not necessary to have the slots
-  in located consecutive address ranges.
-
-  To optimize memory usage and to minimize the number of memory
-  accesses, the memory management is organized as follows (Slot numbers
-  based on mp3PRO):
-
-  1.) Input time domain signal is located in #timeIn, the last slots
-  (0..5) of the spectral data of the previous frame are located in the
-  #OverlapBuffer. In addition, #frameData of the current frame resides
-  in the upper part of #timeIn.
-
-  2.) During the cplxAnalysisQmfFiltering(), 32 samples from #timeIn are transformed
-  into a slot of up to 32 complex spectral low band values at a
-  time. The first spectral slot -- nr. 6 -- is written at slot number
-  zero of #WorkBuffer2. #WorkBuffer2 will be completely filled with
-  spectral data.
-
-  3.) LPP-Transposition in lppTransposer() is processed on 24 slots. During the
-  transposition, the high band part of the spectral data is replicated
-  based on the low band data.
-
-  Envelope Adjustment is processed on the high band part of the spectral
-  data only by calculateSbrEnvelope().
-
-  4.) The cplxSynthesisQmfFiltering() creates 64 time domain samples out
-  of a slot of 64 complex spectral values at a time. The first 6 slots
-  in #timeOut are filled from the results of spectral slots 0..5 in the
-  #OverlapBuffer. The consecutive slots in timeOut are now filled with
-  the results of spectral slots 6..17.
-
-  5.) The preprocessed slots 18..23 have to be stored in the
-  #OverlapBuffer.

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-
-You may not charge copyright license fees for anyone to use, copy or distribute the FDK AAC Codec
-software or your modifications thereto.

-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.

-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.

-\brief Sbr scaling factors,  
-To deal with the dynamic range in the different processing stages, a
-fixed point specific code has to rely on scaling factors. A floating
-point code carries a scaling factor -- the exponent -- for each value,
-so scaling is not necessary there.
-
-The output of the core decoder (low band) is scaled up to cover as much
-as possible bits for each value. As high band and low band are processed
-in different algorithm sections, they require their own scaling
-factors. In addition, any static buffers, e.g. filter states, require a
-separate scaling factor as well. The code takes care to do the proper
-adjustment, if scaling factors of a filter state and the time signal differ.

-    FRACT_BITS-1  zero e.g |max| = 0
-\endverbatim
-
-  Dynamic scaling is used to achieve sufficient accuracy even when the signal
-  energy is low.  The dynamic framing of SBR produces a variable overlap area
-  where samples from the previous QMF-Analysis are stored. Depending on the
-  start position and stop position of the current SBR envelopes, the processing
-  buffer consists of differently scaled regions like illustrated in the below
-  figure.

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional

-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners

-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.

- 1.    INTRODUCTION
-The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
-the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
-This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
-
-AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
-audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
-independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
-of the MPEG specifications.
-
-Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
-may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
-individually for the purpose of encoding or decoding bit streams in products that are compliant with
-the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
-these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
-software may already be covered under those patent licenses when it is used for those licensed purposes only.
-
-Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
-are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
-applications information and documentation.

-You must make available free of charge copies of the complete source code of the FDK AAC Codec and your
-modifications thereto to recipients of copies in binary form.
-
-The name of Fraunhofer may not be used to endorse or promote products derived from this library without
-prior written permission.
-
-You may not charge copyright license fees for anyone to use, copy or distribute the FDK AAC Codec
-software or your modifications thereto.
-
-Your modified versions of the FDK AAC Codec must carry prominent notices stating that you changed the software
-and the date of any change. For modified versions of the FDK AAC Codec, the term
