ADPCM CODEC [message #682] Thu, 08 February 2007 19:18 Go to next message

HuC include some functions to use the adpcm decoder from the CD machine, my question is:

Where can I found a easy to use program to convert classic wav files into adpcm binary compatible with this decoder?

Hi Xavier,

I put up a bunch of ADPCM information on the wiki for you:

http://pcedev.mednafen.com/lick/MSM5205

Check out the bottom of the page for information about doing conversion to and from the ADPCM format using a handy program called 'sox'.

Maybe I should write a demo program showing how ADPCM playback can be done? It might be helpful.

Thanks Charles, I finally tested it, work perfectly. Smile
For info the original sample must be of crystal clear quality ( CD like, mono 16bits 44Khz) because converting an already low quality signal give horrible final result.
