How to boost microphone input volume above 100%? My internal microphone broke, and I have an external microphone on my webcam on an external monitor that is extremely quiet even when the volume is set to 100%.
I tried using Boom, Loopback, and SoundSource, all of them can amplify output (speaker) volumes to above 100% but not microphone volumes.

Is there a way to boost the microphone's input volume above 100%?

Edit:
I'm using it for Zoom meetings, so I need a software that modifies the volume in real-time.
To increase the sound, import the sound file into an iMovie project. Once it is in, select the audio recording and drag the volume slider to anything beyond 100% (you can also click the sound button in the app and increase it from there).
Once you're done modifying the volume, share the iMovie project as an audio file.
