AACEnc is an AAC encoder based on the MPEG-4 sources by NTT. AACEnc is (c)1998 Astrid/Quartex. Currently, it can only encodes 44khz 16 bit WAV files. A MP3 to AAC will be developped in the near future. Don't mail me for other formats. This uses a lot of CPU power, it takes about 1h to encode a 3 minutes song on a P200 at 128kbps. The command line for AACENC and AACDEC has been made simple : 1) AACENC Usage: AACENC [WAV Source file] [AAC Destination file] [Bitrate] [-idle] Bitrates supported are 64, 96 and 128. The -idle option is handy if you want to do other things on the computer while encoding. 2) AACDEC Usage: AACDEC [AAC Source file] [WAV Destination file] Mail: astrid_quartex@hotmail.com And big thanks to Jeremy for his patience and great compilations help, AACEnc would never be here without you.
