Echo Cancellation not working on WinCE
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 lots...

Streaming audio to the waveout device
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 t...

speex echo problem in my own softphone to POTS

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. NickMSN: drawncat at hotma...

No sound in wine.
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.

WAVE PCM to OPUS and back
...unsigned char data[BUFSIZE];
opus_int32 dataLength = opus_encode(m_opusEncoder, (short*)Hdr->lpData, 80, data, BUFSIZE);
dataLength = opus_decode(m_opusDecoder, (unsigned char*)data, dataLength, (short*)WaveHdrOut.lpData, BUFSIZE, 0);
waveOutWrite(hWaveOut, &WaveHdrOut,sizeof(WAVEHDR));
