Sounds like you recorded at 44.1 and are trying to playback at 48.<br>Have you tried changing the project sample rate in audacity? (at the<br>bottom left)<br><br><br>Peter</blockquote><div><br>

Yes, that is what I thought too. But I used the "-f dat" option while
recording, which according to arecord's manpage should have given me
48000 Hz sampling rate. Based on this, I had converted au->flac by
specifying 48KHz sampling rate.<br>
<br>
In audacity I had to reduce the speed (Effects menu) by around 8% to
make the audio replay properly ... this corresponds to 44.1 KHz. (If I
forced audacity to 44.1 KHz from its GUI (lower left), it wouldn't play
the track at all)<br>
<br>
So the "-f dat" option of arecord actually recorded at 44.1 KHz and not at 48 KHz !?<br>
Here is the exact command that I used:<br>
$> arecord -D plug:hw:1 --duration=6300 --file-type au --format=dat --nonblock `date +%Y%m%d%H%m%S`.au<br>
