By smast , July 5, in Logic Pro. When I record audio, there is a slight delay in monitoring and on playback, the part that I recorded is out of sync. Thank you - I tried adjusting buffer size to 64 and there was still a slight delay 15ms, I think but that's not a huge problem - probably because it's a USB interface, I guess.
I still have an issue with it being 'out of sync' once recorded, on playback - could this be because I changed the buffer size after recording the first part? I have switched plugin latency to off and it doesn't make a difference when using the builtin mic. If you still hear delay at 32 samples, with 5ms latency, then your USB interface is not up to the task.
PCI bus is apparently latency free. Firewire and USB busses tends to add more. Some older USB interfaces is more or less useless for low-latency work. If you double the sample rate, you're halving the buffer latency. As you said, there's more to latency than just the buffers.
My new Logic Pro Book is out! I guess it's possible my USB interface is not up to the task but two things confuse me about this:. I didn't notice any latency on either the recorded part or in the monitoring. My Macbook Pro's only a few months old and it's admittedly not the most sophisticated you can get but I'd be surprised if it couldn't handle this I've tried to change a number of variables on the preferences and nothing seems to make a difference to the recorded, overdubbed part being wildy out of sync with the original part Thanks, triplets; I haven't got another interface handy but I did try without the Edirol UA25, just using the built in mic and output of the mac and it's still recording 'out of sync'.
I did notice that on the UA25 driver settings, the buffer size is set in the middle, recording margin is 2ms and recording timing is 0 samples. I might try playing around with that but I guess they're irrelevant when I take the UA25 out of the equation so it seems as though the problem might not be related to UA25 settings.
Unless the fact that the original audio was recorded using the UA25 is important, which seems unlikely to me, at least. I'm relatively new to the mac world and although I know what Snow Leopard is, I'm not sure if I have it I have OS X You can post now and register later.

I'd be grateful for any help, please; many thanks, Stuart. Link to comment Share on other sites More sharing options Sorry, I should have said - that's with Logic Pro 9. Do you hear the delay when you arm the track and listen to the signal? Posted July 6, Also, do you have any latency inducing plugins on the record enabled track or Logic's Stereo Out? Macmini 3. Hi there, thanks - no, I've got no plugins at all.
Just audio one part recorded in stereo on two separate tracks. I tried the computer's built-in microphone and there's still a significant delay on the newly recorded part. Is the delay on monitoring the signal when using built-in mic? At 32 samples buffer size, there is 5. Thanks again. Yes, I mean what you hear in headphones. David Nahmani Posted July 6, Posted July 7, I guess it's possible my USB interface is not up to the task but two things confuse me about this: 1 I used the same interface with different audio sequencing software and did not have any problems.
Yeah, plugin latency compensation is turned off. Sorry to be a pain - your help is much appreciated! Was hoping to work on a project tomorrow but might have to go back to my previous software for now.
Would be interesting to try if using another interface fixes the issue. Software drivers are sometimes the culprit. Are you on Leopard or Snow Leopard? Posted July 8, Yes, you have Snow Leopard. And I assume you have Edirol's latest driver?
Posted July 15, Sorry for the late reply - been away! Yes, thanks, triplets, I have the latest edirol driver. Oh well, I think I'll have to carry out some AB experiments with logic and another piece of software to see what's making it work in the old software and not in logic Join the conversation You can post now and register later.
