Spontanous break up like sound rapidly stopping & starting

Post by Pobinr » Tue Sep 20, 2011 9:59 am

Running 1.3 beta on XP on 2.7Ghz single processor machine with 1.5 GB ram.
Sometimes I get spontanous break up of sound as if the sound it starting & stopping many times a second when over dubbing in record mode & also sometimes purely on playback. It's like a burbling sound.
Perhaps the buffer overspills or something.
Even when other apps closed.
My PC has slowed down lately. Perhaps needs disc reformat which is rather time consuming.
Is there another way to solve this problem ?

Before you reformat, go into drive properties and make sure you're not filling up your drive. Audacity (and most production programs) will not run on a full drive. Time for housekeeping. Do you really need four copies of all those videos?

Then defragment the drive. You may need to do this more than once if you've never done it and it can take a while to organize everything. Audacity won't run into a highly fragmented drive.

Audacity works in layers when you're overdubbing and maintains multiple uncompressed copies of the show. If your machine is starved for resources, it will never make it.

Windows XP does gradually slow down. Defragging the drive and cleaning out some of the accumulated debris can put off the day, but eventually the time to wipe and reinstall arrives.
Try running Ccleaner before you defrag - it is a free utility that safely removes a lot of junk, which is a help in itself, and also makes defragging quicker (less slow).

Thanks to you both. As I already have Norton I will run disc optimiser & defrag too & see if solves it. I have 12Gb free on C drive so I think I'm oK there. But as you say ultimately the registry gets chocked up & reformat is needed. That's the trouble with MS junk. MAC registries don't get congested. Better OS by far which is why I'll be going to MAC one day.

Defrag etc didn't solve the problem.
However the 'audio to buffer' in preferences was set to 100ms. Have increased to 300ms & no more burbling :-)
