Hello, I'm using Speex Preprocessor to supress noise, eliminate echo etc. But I have another preprocessor state that I want to use ONLY to determine voice activity. int res = speex_preprocess_run(m_VADOnly, (spx_int16_t *) pStreamSampleBuffer); pStreamSampleBuffer is modified after call to speex_preprocess_run. I have manually turned off noise suppression and AGC but anyway - VAD modifies

Hi All, I am working on VBR fixed point conversion for our DSP processor and in the algorithm the MIN_ENERGY and some more terms which I am not able to understand how those numbers are derived. Can some one help me with some documentation on algorithm discription of VBR?. Regards, -Prasad

Hi All, I am working on the conversion of float to fixed point conversion of VBR module in SPEEX and in one of the buffer we are storing the last 5 log_energy which is initialised by a constant "MIN_ENERGY" which has a value of 6000. Can some one explain how this 6000 was taken and is this a scaled up version of some floating point number? Regards, -Prasad -------------- next part
