speex echo problem in my own softphone to POTS
...1. prepare a buffer with 4000 bytes deep.
2. "state = speex_echo_state_init( 160, 1280 )" then:
3. put waveData(wHdr) into buffer after "waveOutWrite(hWaveOut, wHdr, sizeof(*wHdr))"
4. in "WaveInCallback" function: Get waveData From buffer, and use "spxec_echo_cancel(state, waveInData, DataGotFromBuffer, tmpBuffer,0)"
5. then push tmpBuffer to Encode Module, package to G.729 to network. NickMSN: drawncat at hotmail.com
