Some of the music always gets lost in translation.” Anyone running a small project studio is no doubt familiar with this and has likely dealt with the mix translation issue by listening on multiple speakers and/or headphones. Whereas for a measurement mic the room’s frequency response changes significantly as it moves around, it normally sounds much more even for a human listener due to brain interpretations of the sounds that we hear.” And as every mix engineer knows, “The acoustic properties of a music listener’s playback system more often than not have little similarity with the setup the artist used when creating the song.

As they state in their Technical Overview of June 2018, “Human beings do not perceive sound the same way a measurement microphone does. Sonarworks has researched sound reproduction and the physiology of sound in humans to determine how perception and sonic spectral distribution relates. I set out to see (hear?) if it does what it claims. There are several versions of Reference 4 available, from software-only to software with a calibrated measurement mic (that I review here) to the full blown Premium Bundle that also includes an individually calibrated Sennheiser HD650 headphone.

The Sonarworks Reference 4 system is one of several available sound calibration systems that aims to correct speaker/room variations in frequency response, and in addition has a headphone mode with a library of generic corrections for over 200 headphones, as well as a unique service to calibrate your headphones to provide extremely accurate and repeatable calibration.
