How to Buy an Audio Interface

If you’re recording music on the computer, you’re most likely going to need an audio interface for recording vocals, guitar, or anything else you plug in (besides a midi controller). Sometimes your internal soundcard is not enough.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• A DAW
• A decent computer

1. 

   Check system requirements and operating system requirements. Macs and PCs will require very different interfaces. Audio interfaces normally run using a software driver so you have to make sure you’re up to speed.

2. 

   Also: check if the interface runs with your DAW (Digital Audio Workstation): Cubase, Garageband, Pro Tools, Logic Pro or Express, Audacity, Adobe Audition, etc.

3. 

   Choose between a preamp interface or an audio interface with no internal power. Keep in mind that the quality of a preamp can be much lower on cheaper models. 40dB might not be enough and it could be distorted. Preamps are useful if you’re taking the interface on the road.

4. 

   Get an interface with more than two inputs if need be. If you’re solo recording, you might not need more than two inputs. If you’re recording an entire band live, you might need eight or more inputs. You’ll want more outputs as well. Look for Midi output is you need it.

5. 

   Look for quality analog/digital conversion.

6. 

   Get a USB or firewire interface. No external power source needed. Some are designed for portability.

7. 

   Look for zero latency—the amount of time it takes for a sound to register after it has been played or sung.

8. 

   Look for a high bit depth and sample rate: 24-bit/96kHz or even higher.
