Continuous popping sound introduced upon importing long field recording

[wopoci]

New to Logic,

I have a long field recording (just over 60 minutes long) I want to edit however when I import it introduces a popping sound that cycles very fast through the whole recording. The original file is a clean mp3.

Any ideas?

Thanks

Perhaps use a different application to convert the mp3 to .wav or .aif and see if the problem is still there.

I have never heard that Logic makes mistakes converting files, but who knows... that would be the first thing I would try.

[wopoci]

I tried that with the same result 😞

Do you get the artifacts when playing the file using another app, like Audacity or Apple's Music? Or do you only get the artifacts when playing it back in Logic?

Also, what app did you use to convert the file?

[wopoci]

I converted the file with Premiere Pro.

No issue with Audacity

And I just tried Apple Music....also no issue

I'm just guessing at this point (and trying to gather more data), but what are the flex settings when you play it back in Logic? Is flex on globally? What about for the region? If relevant, what's the track's flex mode?

[wopoci]

It looks like it's globally off. I turned on for the track but same problem

After analysis it stays on Monophonic

Very strange. Sample rate of the file and the project are the same?

[wopoci]

Hi,

File and project are both 44100

File is 16bit

You may be getting tired of answering these sorts of questions, but in case you're still trying to solve this, here are some more:

- Is the file mono or stereo?

- What format did you convert it to? (WAV, AIFF, etc. - maybe you said earlier, but I didn't see it.) Whatever format(s) you've tried, have you tried other formats to see if you get the same results?

- What's the (approximate) size of the file before and after conversion?

- If you export a, say, 15-second excerpt of the converted file (e.g. using Audacity), does that file exhibit the same behavior in Logic? If so, and if the material is something you're able to share, you could upload a sample of it here for people to check out.

Hey SCG,

Not tired of answering. I appreciate the active help on this forum. I'll investigate what you ask and come back

Thanks

Stereo

Tried Original Mp3 and Converted WAV. Same result

- What's the (approximate) size of the file before and after conversion?

Original Mp3: 60mb Converted WAV: 298mb

I just tried this and the excerpt worked fine. Not sure where that leaves me

I'm probably out of ideas without being able to see the actual source file (which, even if you wanted to share it, I suppose you'd probably have to share via a file sharing service due to its size).

[David Nahmani]

Indeed if you can share the file then we can also try to import it to see if we can reproduce the issue or not.

So I just used Adobe Audition to convert the original file to AAC and it plays fine now in Logic.

So solved! But WTF the problem was I don't know.

Thanks for chiming in everyone.
