If you need an overview of the different kinds of I/O, or what they mean for your workflow, check out our guide to How to Choose an Audio Interface for Your Home Studio.

The first number you’ll see in the “I/O” section is the total.

The inputs are written to the left of the slash and the outputs to the right.

That means an interface with 12 inputs and 8 outputs would be written “12/8.”

Following that you’ll see a breakdown of the different kinds of I/O connections available.

If you’re interested in a particular brand or interface, use the table of contents to go directly to the product you’re looking for.

With that out of way, here’s the interfaces!
