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

Am i following the right steps, is there else i need to do along with the steps i...

Speex echo cancellation and denoise issues

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 be...
