reduction of noise due to high microphone gain
Hello,
With high microphone gain, I seem to have problem making the silence
detection work.
The speech detection works well for the rare dish sample, which has very
low noise amplitudes in silence regions. However, if the microphone
gain is set to really high, noise samples are taken as speech, as
indicated by the non-zero return value from speex_encode() calls.
I had VAD turned on.
