Does anyone know of C source code for low speed CELP or vocoder software available on the net?

I feel if we can develop even a low-speed software based answer to the secure-phone, it will probably be used and distributed to many people. I think it would have to be based around the soundblaster card though.

Perhaps we can also devise an internet secure-phone standard, and clients can be written for NeXTs, Suns, PCs, and etc.

I've had no luck getting our SparcStations to decompress ADPCM encoded Internet Talk Radio in real time...either the software I have is truly sad (could be), or we need to look at other compression methods such as CELP, or at worst, vocoder.

Have you looked at netphone? That should be fairly easy to hack to include encryption, although I haven't looked at the source.. -- Ed Carp erc@wetware.com 510/659-9560 For anonymous mailers --> anonymus+5300@charcoal.com "Disagreements are not meant to be challenges.
