How to boost USB microphone input level

I was having this same problem with the input levels from mics in my Scarlett 2i4 and came across a fix the other day.

You'll need to add the AUPeakLimiter plug-in.

Then adjust the Pre-Gain to the level you need.

Hope this works for you.

Be careful. I would strongly advise against using the Limiter Plugin for this problem. A Limiter has a total different purpose and does other "things" to your audio than just raising the gain.

There is a simple Audio FX Plugin in GarageBand to offset the gain of a Track. It is called Gain and is in the Utility section of the Plugin Menu. It has just one control that lets you adjust the level between -96dB...+24dB. That's it.

BTW, you should look into why your USB mic produces just a low level. Rasing the level is just a band-aid and you might raise noise and other unwanted signals by just cranking up the level.

Hope that helps

When I go into the Audio MIDI Setup app, and attempt to boost the level of my USB microphone from there, the level controls are greyed out and I can make no changes from within that app.

Have you also tried to adjust the input volume slider in the System Preferences > Audio < Input tab?
