Short: Mp3 encoder. (v0.3) Author: mikecheng@cryogen.com (amiga compile), ISO/MPEG/ASSSG Uploader: mikecheng@cryogen.com Version: 0.3 Type: mus/misc Requires: ixemul.library v47+ Replaces: mus/misc/mp3enc* Encoder based on demonstration C source code released by the ISO/MPEG Audio Subgroup Software Simulations Group. NB: No longer does LayerI or LayerII encoding! Version 0.3 (18 Nov 1997) - Added some Stephane Tavenard's memory optimizations from musicin, and adapted for mp3 - Added Henryk Richter's ASM FFT routine from musicin - Added Stephane Tavenard's filter_subband() optimizations. - Implemented a better MDCT routine (70% faster than original) - Sped up a sparse matrix multiplication in l3psy.c - Default encoding is now 128kbs, mp3, stereo, 44.1khz. - Removed all LayerI and LayerII code. Use musicin from aminet for these layers. - Added all the tables into the exe. Now stand alone exe. - Fixed some co-efficients in psy_data (I think). - The dodgy AIFF support in previous versions was due to non-standard AIFF from AHI. - Lots of little niggly things. If you want to help me with benchmarking information, send me your computer specs, the time taken to encode the file, and the actual playing time of the sound file. (NB I prefer timings to be done with Executive's 'timer' command) ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 0 0 0.0% 20-Nov-97 02:06:40 + 222676 82839 62.7% 20-Nov-97 00:14:26 +encode020 192416 74773 61.1% 20-Nov-97 00:14:36 +encode020881 234584 90702 61.3% 20-Nov-97 00:14:36 +encode040 7910 3605 54.4% 20-Nov-97 02:11:24 +mp3enc.guide 1317 770 41.5% 20-Nov-97 02:03:46 +mp3enc.readme -------- ------- ----- --------- -------- 658903 252689 61.6% 25-Nov-97 06:34:18 6 files
