Best Audio Interface Under $1000 in 2021

I always say that declaring a product or another to be the best of its kind is misleading. There is no such thing as a general best. The best audio interface is the one that best suits your needs and setup. However, to make this an objective evaluation we will be looking for i/o format and flexibility, A/D D/A conversion, preamp quality, connectivity, and integration. I believe these qualities factor in the most in telling how good a certain product is.

It converts to digital and back at 24 bit, 192 kHz with 118 dB of dynamic range on the preamp.

The Scarlett series from Focusrite is quite amazing. So much quality for so little money – it really shows how democratized music-making has become. The build quality and the components are what you would expect to see in something that’s tagged as “professional”. All the products in the series feature 8 pristine and neutral mic preamps and up to 24 bit, 192kHz, 106 dB dynamic range digital conversion make sure that your recordings will sound off the hook. Midi, S/PDIF and ADAT i/o (8 in/ 8 out) are big pluses for this interface. It has a total of 12 outputs. (8 general + 2 headphone outputs + 2 main outputs). It integrates seamlessly with any DAW set up and it comes bundled with a whole bunch of quality plug-ins. While the first generation did not offer AAX support for the bundled plug-ins, this has changed for the second generation so Pro Tools 11+ users can take into consideration the valuable bundled plug-ins when considering a buy.

The UR 824 is a very respectable player in the audio interface arena. It is equipped with very neutral and low noise Yamaha D-Pre mic preamps and can convert to and from digital audio at 24 bit, 192 kHz with 105 dB of dynamic range. It comes standard with 8 analog inputs and 8 outputs but you can extend that to 24 by 24 if you connect external mic preamp modules via the two pairs of ADAT i/o. On top of that, it features clocking i/o and S/PDIF (via ADAT).


The above-mentioned audio interfaces are all great options. The trick is finding out which one works best with your setup. If you have a tiny home studio you probably do not want a 2U interface eating up all your space and the UAD Apollo Twin Duo will be a far better match. Or, for example, maybe your system does not have a Thunderbolt port. It is factoring in all the details of your system and your needs that contribute the most to making the right decision.
