What is an audio interface?

An audio interface is a piece of equipment that converts analog signals, such as the sound of a guitar, bass, or other musical instrument, or the voice of a vocalist, into digital signals for input into a computer, or converts digital signals into analog signals for output to speakers.

An audio interface will be able to record sound louder because it will be able to amplify and input low output sounds such as guitars.

This reduces the amount of noise and makes it possible to record in an easy-to-hear quality.
