Full Technical Explanation

An interface in audio systems refers to a device or software that connects different technologies and allows them to communicate effectively. The most common example is an audio interface, which converts analog audio signals from microphones, instruments, or mixers into digital data for use with a computer or digital audio workstation (DAW), and vice versa. Interfaces often include preamps, converters, and I/O (input/output) options. They may also facilitate protocol translation between standards such as USB, Thunderbolt, ADAT, or AES/EBU. Interfaces are essential in both professional and home recording environments for signal routing, conversion, and integration across devices and platforms.
