I have an Audacity project with around 25 tracks, absolutely no overlap between them. I'm trying to record from a microphone with some overlap and the playback gets really chopped while recording and probably the recording is broken as well.
his is running on a Ubuntu 9.10 box that has 3GB of RAM and an Intel Core 2 Duo CPU (1.83GHz).
Any ideas what might be the problem?

Can you adjust an audio buffer/latency setting? This will make the CPU work less, but it will take longer to get audio in and out of the audio interface.

I've had the same problem recording audio playback from qsynth with JACK, the audio always got chopped in fixed intervals.
The solution was to go in Edit → Preferences... → Recording and set Latency Correction to 0.

I encountered that problem on a slightly less powerful machine: trying to record another track when there are some already in the project resulted in somewhat interrupted sound. This is some performance issue in Audacity; I solved it by creating a new project for each track I was recording and then merging them afterwise. Sorry, no better solutions.

Preferences > Audio I/O > Audio to buffer
That will most likely be it. Put a value of 512 in there. Double it if that doesn't work. – Sam – 2010-01-21T04:49:22.057
How do I change the buffer/latency? – pupeno – 2010-01-20T19:59:32.510
Have you tried poking around any preference areas in the application? I don't have it in front of me now. – Sam – 2010-01-20T22:04:30.413
