This new code includes lower sampling frequency (LSF) extensions. + - added in most of the changes already done. + - LSF mode is faulty. Seg faults after about 190 frames here. LSF mode works if you turn off psy models though (-f) + +v0.2b - released 30 October 1999 + - added a "-q n" mode. will only calculate the psy model every n frames. + "-q 0" is equivalent to "-f". + - reimplemented "downmix to mono" -a switch + - WAV file support from Nick Burch + - some code cleanup - removed more LayerI & III stuff. + +v0.2c - skipped this release + +v0.2d - released 6 November 1999 + - used Mathew Hendry's enhanced fht() with table lookup (20% faster) + - made add_db an inline function and tweaked it (25% faster) + - code cleanup - renamed psy.c->psycho_II.c, tonal.c->psycho_I.c, other misc stuff + - added a "no padding" (-r) switch. Needed by the rfa.org (thanks to Federico Grau) + - tweaked threshold 33% speedup. + +v0.2e - released 14 December 1999 + - Some minor speedups from PDS in encode.c + - Changed // comments to /* */ style + - Merged some functions in subband.c + - Cleaned up file input parsing a little. + - Now reads PCM from /dev/stdin if this is specified as input filename (kludgy but works for me) + - Started putting tables into exe. (only enwindow done so far) + +v0.2f - released 15 April 2000 + - mainly cosmetic changes in the source and code layout + - removed a lot of unused functions, and split common.c into more logical subumits. + - about 15-20% faster when using psymodel I. (merged some functions in psycho_i.c) + +v0.2g - released 22 April 2000 + - added a VBR mode. See README.VBR + - cleaned up more code. + +v0.2h - stdio/stdout now parse a little better using '-' + - tables now included in the exe thanks to Oliver Lietz + (I haven't had a chance to test it much though) + - including the tables in the exe seems to have boosted speed quite a bit (25%?) + - re-implemented byte-swapping in get_audio.c (command line switch -x ) + +v0.2i - Released 13 July 2001 + - DAB extensions from Phillipe Jouguet + - Added a switch to swap the input channels (can someone confirm that toolame + swaps them incorrectly by default) + +v0.2j - Released 13 February 2003 + - Definitely LGPL + - VBR mode is stable for all sampling frequencies.
