On my WinCE board I am using WaveIn/WaveOut functions to record and playback
I am receiving audio data on udp socket, then playing it on speaker using
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 of
My microphone and speaker are on same sound card and running at same clock
Does anybody tried echo cancellation using WaveIn/WaveOut functions?
I also want to know that how to find delay between speaker data and data
captured from microphone on Windows(WinCE).
Please help me.
Thanks in advance.
