It is based heavily on - the ISO dist10 code - improvement to algorithms as part of the LAME project (www.sulaco.org/mp3) - work by Mike Cheng and other contributors (see CONTRIBUTORS) CONTRIBUTORS ============ Dist10 code writers LAME specific contributions fht routines from Ron Mayer fht tweaking by Mathew Hendry window_subband & filter_subband from LAME circa v3.30 (multiple LAME authors) (before Takehiro's window/filter/mdct combination) Oliver Lietz Tables now included in the exe! (yay! :) Patrick de Smet scale_factor calc speedup. subband_quantization speedup Federico Grau Bill Eldridge option for "no padding" Nick Burch WAV file reading os/2 Makefile mods. Phillipe Jouguet DAB extensions spelling, LSF using psyII, WAVE reading Henrik Herranen - leopold at vlsi.fi (WAVE reading) Andreas Neukoetter - anti at webhome.de (verbosity patch '-t' switch for transcode plugin) Sami Sallinen - sami.sallinen at g-cluster.com (filter_subband loop unroll psycho_i fix for "% 1408" calcs) Mike Cheng (remove the NOT) Most of the rest Matthias P.
