Before you buy
- Count the inputs you need to record at the same time
- Check which ports your computer has: USB-A, USB-C or Thunderbolt
- Decide how many outputs you need for monitors and headphone mixes
- Look for ADAT or S/PDIF if you may want to expand later
- Check driver support for your operating system and DAW
Frequently asked questions
What does an audio interface do?
It converts analogue signals from microphones and instruments into digital audio for your computer, and converts the playback back to analogue for your speakers and headphones. It also provides preamps, phantom power and a headphone output.
Do I need an audio interface for home recording?
If you want to record microphones or instruments with good quality and low latency, yes. A computer's built-in sound card is not designed for that, and it has no microphone preamps or phantom power.
What is the difference between USB and Thunderbolt audio interfaces?
Both can sound excellent. USB works with almost every computer and is the usual choice for home studios; Thunderbolt connects more directly to the computer and suits low-latency work and high channel counts.
How many inputs do I need on an audio interface?
As many as the sources you record at the same time. Two covers vocals and an instrument; drums and full bands need eight or more, or an interface with ADAT to add channels.
Can I use an audio interface with an iPad?
Yes, if the interface is class compliant. You may need a USB-C or camera adapter, and a powered hub or external power supply if the iPad cannot power the interface.
What is latency and how do I reduce it?
Latency is the delay between playing and hearing the result through your computer. Use direct monitoring while recording, a smaller buffer size in your DAW and up-to-date drivers.
How much should I spend on an audio interface?
Spending more usually brings more inputs, quieter preamps with more gain, better converters and features such as DSP and digital expansion. For one or two sources, an entry-level interface already records very well.
Can I try an audio interface before I buy?
Yes. Products marked In Store are on the shelf in our Rotterdam showroom at Oude Binnenweg 38, where you can try them.
