The Computer Audio Interface Guide

This guide covers computer audio interfaces (sometimes referred to as "I/O"s or "breakout boxes") for PC or Mac. These provide audio input, output and additional features which improve upon any built-in audio jack. This guide does not cover internal PCI cards, just external connectors (USB, FireWire etc). See the bottom of this page for an intro to the terminology and trends.
