why VAD modifies my voice data?
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 my data. Is there a solution? All I want is to know whether voice present or not.. I do not need any voice modifications itself. Thanks a lot! Reg...
