Before recording audio in GarageBand on Mac
You can record your voice, an acoustic instrument, or any other sound using your computer’s built-in microphone or a microphone connected to your computer. You record sound from a microphone to an audio track.
Before you start recording audio, do the following:
Connect a microphone, an electric guitar, or another instrument to your computer and make sure the microphone or instrument is working.
Select the audio track you want to record to, or add an audio track. Be sure to set the input source, input volume level, and monitoring for the track.
Set the recording bit depth, which is the number of digital bits each sample contains. The higher the bit depth, the greater the dynamic range of the audio data.
Tune any instruments that you are recording to ensure that your audio recordings are in tune with any software instruments, samples, and existing recordings in your project.
