Recording sync Issues after Upgrading from i7 to M1

Thank you. I tried low latency mode to no effect.

I then deleted preferences via logic, deleted all logic folders under /Library and ~/Library sub-folders, cleared out some old audio plugin files, preferences, and cache, deleted Logic, rebooted, reinstalled, downloaded extra content, rebooted, and tried recording with and without your suggested settings.

Sadly, the issue persists--and I'm only using the internal mic and speakers; nothing else in the chain to cause issues.

Next, I took myself out of the test by recording the sound of the logic metronome coming from the speakers. The audio region should show the metronome impulses right on the beat, but they're offset just like my previous tests (80-100 ticks). I tried with different buffer sizes too. No real difference.

One last observation. If I arm a track to record or enable track monitoring and then clap, the meter exhibits the same delay I see in my recordings. In my prior experience, metering of mic inputs has always been near instantaneous.

This has got to be just my system, right? There's no way something this fundamental could pass software testing.

Hi, Polarity-1. I ran your test and observed the same recording offset. In my case around ~80 ticks.

I then checked the "software monitoring" option, which I found in the main logic preferences > Audio tab--I couldn't find it under project preferences. But here's the weird thing. that checkbox is disabled. I can't check or uncheck it. What on earth does that mean?

Thanks. Yes, I tried at all sample rates (44.1 thru 192KHz) with no change in delay.

For my latest tests, I used no plugins at all.

1. Open Logic
2. Create new blank project (no template)
3. Add an audio track
4. Enable metronome
5. Mute and arm audio track
6. Record a few measures (mic records metronome sound from speakers)
7. Observe recording alignment

But I probably do still have some older plugins installed that aren't native M1. I tried clearing out most of them this morning, like some old Waves plugins and others. A few still appear in the plugin manager and are disabled.

I ran the same test in some other several DAWs. Here are the offsets (positive or negative) in milliseconds:

• Logic Pro v10.7.4 +42ms offset
• Audacity v3.1.3 +244ms offset
• Studio One v5.8.2022 -25ms offset
• Ableton Live v11.1.6. +98ms offset

It's a confounding issue for sure. I've been doing multitrack recording since the late 90's, using DAWs like Sound Forge and Acid Pro on budget PCs, and I've never had this issue.

...and the whole point of the metronome is to keep your recordings aligned to the beat. How is such a fundamental feature broken on Apple's Hardware, running Apple's OS, using Apple's DAW? Guess the best I can do is adjust the recording delay until they fix it.

• First impulse is offset by ~80 ticks. Should be at very start of track.
• All impulses are off by the same ~80 ticks
• Audio device settings shown
• No plugins used
• No external devices
• 44.1KHz
• Logic preferences reset before setting up and starting test

Yes, I've ruled out various audio equipment and narrowed it down to the MBP hardware itself. All my recent tests have been with the MBP internal speakers and microphone.

I did. GarageBand had the exact same result.

I appreciate your help. Thank you. I'll look into doing a factory reset and starting fresh then do some research on 12.5. If anything changes I'll update this post.
