Hi *,
for LinuxTag, I thought a nice demo would be to show some kind of
vocoder under Linux. My idea goes like this:
- Put two soundcards in a machine, one gets input from a microphone, the
other gets string-type chords from a synth.
- The vocoder software uses these two as carrier and modulator to
produce some nice alien/space/scifi type of sounds/voices
- This is put out again through one of the two soundcards. Both are
Emu10k1 based, so I think both are able to do duplex pcm
recording/playing at 16 bit.

- Of course, all of this should be done in realtime.

The only question I have: What software to use? I have found a few links
at Dave Phillips' page, but I have no experience with these programs; do
any of you have actual "stage experience" with one of them?

Names I found:
- Packages from the NoTAM group
- PVC
- PVNation
- XVox
- Zerius Vocoder

Opinions, anyone?

Thanks,
Frank
