Have you tried using the (less accurate) VAD that's in the codec itself (SPEEX_SET_VAD)?

Hello all, I'm trying this code in Delphi but it does not seem to work: LStub1:= 1; LStub2:= 0; acmStreamMessage(hStream, ACMDM_USER+30, LStub1, LStub2); // 30 = SPEEX_SET_VAD Is there a way to turn VAD on for Speex ACM? Thanks in advance, Ivan.

No. Speex expects values in the +-32767 range, not +-1.0. Just converting from int16 to float *is* the right thing to do. Jean-Marc -- Jean-Marc Valin <Jean-Marc.Valin@USherbrooke.ca>

In this case [in the conferencing application], I'm not actually using speex encoding [these are PSTN callers, I do VAD in clients when I control them], so I'd need to see if I could rip it out of speex to use it. Also, I do have a couple of...
