Audio Recording is Slow

Asked by Bazzle on 2008-07-10

I recently bought a plug-and-play usb microphone (the blue snowflake). I plug it into my laptop running ubuntu, go to audacity and set the snowflake as the recording device. I press the record button and audacity starts recording through the microphone. I stop the recording and play it back, and the playback is much slower than the recording, distorting the sounds. I tried recording in VRS too, and I got the same problem. How can I fix it so that recording is at actual speed, not in slow-motion?

I can sort of fix the problem by changing the playback speed to double-speed in postprocessing, but this still does not completely fix the problem of recording at half speed.

Nobody seriously knows anything about this? I mean my guess is that it has to do with ALSA, but I have no idea how to mess around with that.

I noticed the same problem with the Blue Snowball microphone (also USB). I am also not sure how to proceed. I tried different sampling rates and bitrates, but nothing seemed to fix the problem.

Btw, I found this question via Google search. Perhaps it belongs as a bug instead of in the Answers section.

Can you help with this problem?
