Replying to richardpl:
What created such files?
Adobe Audition

Useless, i need specification so I can know what tables are used for non 4-bit cases. And I'm not going to hunt for big applications that can encode/decode such files. So something small as dll that does actual decoding or even better specification is required.

The last one is most useful. Could you also upload mono files (created with same tool)?

I'm not sure what does it mean? You don't like rar archive or what? UnRAR is available for linux and AFAICT p7zip can decompress it as well.

I do not have it installed and do not want to install it, because it is not free.
