A new format is born : Audio Multichannel 1.0 (AM1

2003-06-17 17:58:20

Hello,

I work on my own audio format, based on ADPCM and Huffman coding. For the moment, I can encode my audio file with in 8:1 (4:1 for ADPCM and 2:1 for Huffman encoding)
To reduce the ratio and the bitrate (too high, but with very quick encoding/decoding), I would like to include a very simple/minimalist psychoacoustic model. I seach a Pascal source, or Delphi source, with this minimalist implemenation. My first goal is to have 12:1 ratio, like MP3 in 128 Kbps for stereo file. (In fact, 64 Kbps for each channel)
Have you a website (with explication, and code example), or a source, to make that ?
For the moment, I read many PDF document with psychoacoustic explications but I need help to include it in my encoder (a program in command line for the moment)
To finish, my format (named for the moment AM1, for "Audio Multichannel Vers 1.0") can encoding in 24 bits, 96 Khz, support encapsulation - many files in one big file - watermarking, audio crypting, digital right management, and - off course - multichannel encoding (7.1)... This format is for movie and for music.

My code work perfectly, but the encoding ratio is to loo...

In advance, many thanks for your answer...

Best regards,
