...in preprocessor is very good, there is not noise outside speech.

I implemented the calcPower(). It works perfectly. The example is given you in just about 6 hours. Cant paste the whole source here and need to meet someone now. Thanks all (particulary tom).

...the mixer up and v.v.). This appears to be effective. So is there a way to make these items available to speex clients? The speex_preprocess_ctl interface could be extended, but it's not really what it is intended for, is it? Also, can anyone clarify the new use of speex_preprocess_ctl for SPEEX_PREPROCESS_SET_PROB_START/CONTINUE? It used to have a float parameter, and it now seems to be int, but I couldn't get it to set the value correctly and have had to change speex_preprocess_ctl back to using a float. David

...in preprocessor is very good, there is not noise outside speech.

To overcome this problem, are SPEEX_PREPROCESS_SET_PROB_START, SPEEX_PREPROCESS_SET_PROB_CONTINUE parameters or if (st->nb_preprocess%200==0) in preprocessor.c (line 608) useful?

Sorry. I forgotten the words volume or loudness. But it is know as microphone stroke too, i think. If something can tell me something about that procedure it would complete my pleasure. To bring back memories, i only wanted to know wheather i can change a variable that holds the sound intensity (loudness) needet to start "encoding >> sending" if the speex codec is in voice
