Weird crackle in Logic
Wednesday, April 10 2019 @ 12:57 PM CDT

I've been working on a new song and when I opened it today I realised there was a nasty crackle on play back.

It sounded as if the speakers were blown but they aren't.

I found that if I soloed a track the noise appeared only when there was sound on the track. Any gaps were silent.

I have no idea where it came from. It's happening on all audio tracks (but not midi).

I copied some of the tracks into a new project and they play fine so the noise isn't on the recorded track.

As far as I know I've not set or unset anything and other projects are playing Ok.

I've now created a new project and copied all the tracks across and it plays without the crackle.

Any ideas what the might be happening?

Thanks

Dick

I have no answers to your question of what it is- I prefer to call it a ghost.
I can tell you that you are not alone in discovering the ghost.
The methods used to escape the ghostly touch, as you describe them, work. I have not been able to remove the phenom once it appears. A project where a ghost appears must be abandoned and restarted.
Best of luck.

In this case the ghost has won and a new project it is Smile

Had it happen to me once some years back.

Yeah... one just has to start over.

“Sometimes ... ka-ka ... occurs ...”

... and you never do figure out why.   (Nor do you particularly care, once it’s gone.)

As an IBM representative once told me about an apparently-recalcitrant mainframe computer ... “well, did you try turning it off and back on again?”   (It worked.)

Could be your sample rate.

Are sure your audio interface is set to the same sample rate as your project, sometimes switching to 48KHz then back to 44.1 can fix this problem.

A crackle can also happen if you recorded audio at one sample rate, but are trying to play it back at another without converting it.

Thanks Nahum. Nice to see you here again!

It's a good idea but as far as I can see there are no differences anywhere.

It started one day on that project and other projects are unaffected. I copied the audio into a new project and it's fine.

All very odd.
