What is an Audio Interface

An audio interface is a device that connects external audio sources to your computer. It typically includes both audio input and output components. While every consumer computer comes with a basic built-in audio interface, allowing you to use the computer’s microphone and speakers for input and output, an external audio interface offers superior sound quality and additional features. Configuring your playback engine in your audio software determines which audio interface you use, providing greater flexibility and control over your audio setup.

The Importance of Configuring the ProTools Playback Engine

ProTools needs to interface with the outside world in order to send and receive sound. 90 percent of the problems in ProTools can be attributed to having the wrong playback engine selected.

Accessing the Menu Option

First, we need to access the correct menu option. We can adjust the Playback Engine in the "Setup" menu.
