[Rap Recording] What’s the difference between the mic input and the line input on an audio interface?

The mic input is for microphones. The line input is for keyboards, synthesizers, mixers, etc. You can also record guitars with the line input, but the HI-Z input is preferable. If you have an acoustic guitar, it’s really cool to record it with a microphone.

If you’re rapping, you’ll probably only use the microphone input.
