i'm optimizing some features....for exemple why not doing this : ------------------------------------------------------------------------------- void speex_bits_advance(SpeexBits *bits, int n) { if (((bits->bytePtr<<3)+bits->bitPtr+n>bits->nbBits) || bits->overflow){ bits->overflow=1; return; } bits->bytePtr += (bits->bitPtr+nbBits) >>

another optimization you can do for packing bits together... the original one is : ------------------------------------------------------------------------------------------------------------- void speex_bits_pack(SpeexBits *bits, int data, int nbBits) { int i; unsigned int d=data; if (bits->bytePtr+((nbBits+bits->bitPtr)>>3) >= bits->buf_size) { //remain

Hi Jean Marc, I found that the AGC API and algorithm has changed in svn head trunk. Is it safe to use it? Or is it for testing purpose only? You also said that VAD in svn is broken in a previous post, is it related to the AGC change? or can we mix the old VAD algorithm with the new AGC safely? kind regards, fredo

I'm going to test the echo cancellation... but before doing something wrong, i want to know what is the right way to use it... ------------------------------------------------------------------------------------- short * speakerSample; //will contain what the speakers are going to play short * microphoneSample; //what the microphone is going to register short* cancelledSample; //the ouput
