Audio Interfaces

An audio interface converts your microphone signal into digital audio and returns sound to your headphones. It is the bridge between XLR gear and your computer.

Buying advice

  • Count your inputs. One host needs one input; a two-person show needs at least two.
  • Check the preamps. Clean, quiet gain matters most if you use a low-output dynamic microphone.
  • Look for direct monitoring so you can hear yourself with no delay while recording.

Specifications to understand

Number of inputs
How many microphones you can record at once.
Preamp gain
How much amplification the mic input can provide. Important for dynamic mics.
Sample rate and bit depth
Most speech work is fine at 48 kHz / 24-bit. Higher figures rarely matter for voice.
Connection
USB-C and USB-A are common. Check that your computer has the right port or use a suitable adapter.
