Hello Friends, I am trying to use speex-1.2beta3 version for echo cancelling. On my WinCE board I am using WaveIn/WaveOut functions to record and playback audio. I am receiving audio data on udp socket, then playing it on speaker using WaveOutWrite function. I registered callback to capture microphone data, then data chunk came from socket ( which I played on speaker) and data captured from microphone is provided for echo cancellation function, but no echo getting canceled, instead after 10-15 seconds output of echo canceler audio having lot...

Hi, Please excuse my ignorance but I'm having trouble with a very basic matter: I'm using vorbisfile to stream audio to the waveout device in Win32 (using waveOutWrite). I'm basically reading packets from an ogg file and streaming them using a simple buffering scheme. The thing is, this works great when the bitrate is more or less constant but the audio sounds garbled if there is a radical bitrate change. Which makes sense but I don't know how to handle...

...n TraditionalPhone. It seems SpeexEcho stops to work. What I have done In my softPhone project with SpeexEcho are these: 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.

err:winmm:proc_PlaySound Aborting play loop, waveOutWrite error That's my output when I try to play a test sound. I'm able to actually play StarCraft, but I can't get the sound to work. I have PulseAudio and ALSA installed, just not sure how to configure either.
