Are you experiencing a crackling noise when using GarageBand? There are a number of things that can cause audio distortion in GarageBand, including faulty cables, the adapter you are using, or incorrect sample rate settings. Read on to learn how to troubleshoot distorted Mac audio in GarageBand.
How to Fix Crackling Noise in GarageBand
Faulty equipment is the most common cause of a crackling noise in GarageBand. It could be due to the cable, port, or interface adapter.
Try using a different cable and interface adapter. If you have a cheap interface adapter that’s been in use for a while, get a new one. Also, try plugging the cable into a different port on your Mac. That often fixes the issue.
You should also check to see if it’s a speaker issue. Try using different headphones or speakers.
Another thing worth trying is ensuring the sample rate is aligned with GarageBand’s. In the Audio MIDI Setup app on your Mac, which you can find in your Utilities folder, you can adjust the sample rate. You may be able to adjust the sample rate for your interface as well, depending on the interface. Remember that GarageBand is fixed at 44.1kHz, so try aligning everything to that sample rate.
You’ll also want to make sure that both GarageBand and macOS are updated. Sometimes, outdated software or drivers can cause such issues. You could also try installing and reinstalling GarageBand.
How to Reduce Static Noise in GarageBand

To reduce static noise, use the noise gate. This is built into GarageBand, although there are also third-party plugins you can install as well. Follow these steps:
- Select the track.
- Click on the headphone icon.
- Open the Track Info window and expand it.
- Click on the Gate checkbox.
- Play the song.
- Adjust the Gate slider to reduce static and background noise.
