* Remove __DATE__/__TIME__Dan Willemsen2015-10-231-0/+5
| | | | | | | | | | | | | Building __DATE__/__TIME__ into the binaries means that every build will create different binaries, even if all the sources are identical. This also means that any libraries including this one will need to be patched during every OTA. Nothing appears to use the build_date/build_time fields, so just replace them with empty strings.

* AAC-Decoder: SBR delay for gaplessJean-Michel Trivi2014-05-201-6/+9
| | | | | | | | | | Revise decoder output delay determination. The output delay consisted of concealment and limiter delay. SBR delay was not covered but must be considered for gapless playback delay compensation. Bug 9428126 Change-Id: I67483712c284de9b5378694f9db7acbed2547dd7
* AAC-Decoder: DRC metadata in stream infoJean-Michel Trivi2014-05-206-7/+77

* AAC Decoder: flush/seek improvementsJean-Michel Trivi2014-05-204-21/+61
| | | | | | | | | | Improve flushing and seeking. Add field to the API stream info structure signaling the additional output delay for flushing and delay compensation. Bug 9428126 Change-Id: I808412905563ea3de50a2e77a9b5dfee829cd2ed
* AAC Decoder: introduce time domain limiterJean-Michel Trivi2014-03-317-12/+159
| | | | | | | | | | | | | Introduce time domain limiter. The module is per default enabled for all AAC-LC and HE-AAC v1/2 streams. For all ER-AAC-LD and ER-AAC-ELD streams the limiter is disabled per default. The feature can be en- or disabled via dynamic API parameter. Note that the limiter introduces an additional output delay which depends on the module parameters and the streams sampling rate. Bug 9428126 Change-Id: I299a072340b33e2c324facbd347a72c8de3d380e
* AAC Decoder: support 6.1/7.1 decoded as 5.1Jean-Michel Trivi2013-12-309-126/+252
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add 6.1 and 7.1 channel support including downmixer. Per default the decoder creates a 5.1 channel output for all streams with more than six encoded channels.

* Don't zero out spec coeffs before doing the final IMDCT.John Grossman2012-09-121-4/+1
| | | | | | | | | | | | | | | | | Addresses bug 7140347. When flushing the decoder, you need to make sure to zero out any lingering spectral coefficients as well as zero out the overlap buffer state after decoding the final access unit. Zeroing out the spec coefficients *before* you decode the last block, however, seems like a mistake. If the final block contains any useful information for the stream, then you end up outputting the overlap portion of the second to last decoded block combined with zeros. Because of the shape of the second to last block's windows, this results in what appears to be a fade out, but actually is a zero'ed out final block.
