If you’ve outgrown your audio interface and want to replace it with something more flexible, you’ll need to look beyond the number of inputs and outputs on offer. To help you choose the best audio interface for your needs, we’ve put together a list of five things to consider.

1: You’ll need more than eight inputs
How many inputs do you need? This isn’t as simple as counting your audio sources and making sure you have enough inputs:
Many musicians consider an eight-input interface to be sufficient. But this is actually the minimum number of channels needed for recording a live rock band: four mics for your drum kit plus guitar, bass, vocals and a mono keyboard.

2: Multiple outputs: can you send sound to different parts of the room?
The ability to hear your mix on different speakers (or monitors) is one of the most common reasons for having multiple outputs, but there are many other uses too:

3: Portable audio interfaces are far more practical
If you’re recording or live mixing a band, you’ll need an audio interface that is easy to carry and easy to use once the session begins.

4: Flexible monitoring gives your band members their own monitor mix
Separate monitor mixes are essential for studio and live recording. Imagine having different cue mixes for different musicians – more vocals for the vocalist, more bass for the bass player or different monitoring for wedges or in-ear monitors.

5: Build quality matters – the cheaper option can be more expensive
If you’ll take your interface on the road, it’ll inevitably get knocked about.

Make sure you look for an interface that is well built – cheap plastic casing smashes easily when dropped.
