An audio interface is a device that allows you to connect your musical instruments and microphones to your computer. It converts the analog signals from your instruments and microphones into digital signals that can be processed by your computer’s software. This allows you to record, edit, and mix your music using your computer.
There are many different types of audio interfaces available, each with its own features and capabilities. Some audio interfaces are designed for specific purposes, such as recording guitars or vocals, while others are more general-purpose and can be used for a variety of applications.
