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.
(Sort by clicking a header. Filter by selecting a port. 97 interfaces match current criteria. See all interfaces.)
