Hi folks, i'm looking for some help. I've been given an audio track to fix which came from a DV recording. It is 16bit/44.1, but what confuses me is i thought audio for video was usually 24bit/48. When i play back the audio, it is sounding very jittery with electronic-sounding "spikes" throughout. Every now and again it smooths out, only to fall back into sounding bad again. I've tried to change the sample rate for playback with no success. Has anyone ever experienced this issue and, if so, do you have a solution for me? Any help is greatly appreciated!
P.S. I use Logic Express. -------------------- Luke Davison

It's difficult to say what is the source of the issue. maybe a 48k files incorrectly stamped as 44k, but this is not jitter.
Jitter is a (small) variation in the computer clock frequency causing quality losses, but not as uggly as you describe. If you can, I think you'd rather to get the original DV tape and transfer the audio track yourself, using firewire. That is certainly at this stage that something weird happened.

Thank you very much for your reply, greatly appreciated! I will be obtaining the DV and doing the transfer again.
