The "click" is smooth, and extends over about 20 time steps. It also has ringing associated. Are you sure that you are not doing frequency interpolations? Ie recording the thing at 4KHz and then extrapolating to 44100? Ie, this waveform looks very processed. It is really hard to imagine that alsa could have produced it due to some bug. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
