What is it

SoundID Reference is a standalone app and a DAW plugin that calibrates speakers and headphones to deliver an accurate studio reference sound.

For whom

Made for audio engineers, producers, musicians, DJs, composers, sound designers, game developers, and audiophiles.

What it does

SoundID Reference ensures perfect translation so you can create music that sounds great on phones, laptops, earbuds, or wherever else its played.


By working with the same reference sound with your colleagues and clients, you can save time and money, no matter the distance or gear you have.

How it works?

Even the best speakers can't compensate for the acoustics of a poorly designed room. SoundID Reference compensates for that by measuring the frequency response of your room and speakers to create a calibration profile. For headphones - simply apply a pre-made calibration profile available in the software. With calibration applied, your music will sound great everywhere.
