Speex issue
...'s some glaring error that you guys will shout at me
for missing. This method is called when enough data has accumulated in
inputFrame, after the members have been initialized and the headers have
been written:
oggPacketCount++;
speex_bits_reset(&speexBits);
speex_encode_int(encoderState, inputFrame, &speexBits);
int packetBytes = speex_bits_write(&speexBits, packetBuffer,
PACKET_BUFFER_SIZE);
oggPacket.packet = (unsigned char*)packetBuffer;
oggPacket.bytes = packetBytes;
oggPacket.b_o_s = 0; //this is not the beginning of the stream
oggPacket.e_o_s...

Denoise not working for me
...tate_init(160, 8000); //20ms audio at 8000 bps
speex_preprocess_ctl(SpxPreprocessState, SPEEX_PREPROCESS_SET_DENOISE,
&nEnable);
//Run the preprocess on the buffer captured before encoding
speex_preprocess_run(SpxPreprocessState, (short*)pbBuffer);
speex_encode_int(EncoderState,(short*)pbBuffer,
&stSpeexBits);
I dump the output of the buffer after calling speex_preprocess_run and play
it using some media player tool but I dont hear any audio as if the complete
audio has been removed. Am i following the right steps, is there else i need
to do along with the steps...

Speex echo cancellation and denoise issues
...ate_init(160, 8000); //20ms audio at 8000 bps
speex_preprocess_ctl(SpxPreprocessState, SPEEX_PREPROCESS_SET_DENOISE,
&nEnable);
//Run the preprocess on the buffer captured before encoding
speex_preprocess_run(SpxPreprocessState, (short*)pbBuffer);
speex_encode_int(EncoderState,(short*)pbBuffer,
&stSpeexBits);
On calling speex_preprocess_run removes all the audio from the buffer and a
constant humming sound is heard. I open the recorded file in Cool edit pro
tool and see that all the spikes are removed and flat wave is there. What
could...
