Audio software developer Sonarworks has released Reference 4 sound calibration software – Sonarworks SR, promises to resolve the problem of disparate sonic reference points for audio professionals, delivering the same reference sound on speakers and headphones.

Sonarworks Reference 4

Sonarworks SR sets the frequency response of a system to replicate neutral monitor speakers in a treated room. The calibration of headphones is done using a profile pre-measured in Sonarworks’ lab, while speaker calibration profile is produced by a user on-the-spot using Sonarworks measurement software.

‘The entire professional audio community is acutely aware of the fact that every room and every headphone invariably has the effect of colouring sound,’ says Sonarworks VP and co-founder, Martins Popelis. ‘This has had an enormous negative impact on both costs and productivity – not to mention creative workflow. We estimate that at least one-fifth of the effort in the music industry is spent dealing with translation issues.

‘With Sonarworks SR, we have an opportunity to align the entire audio industry on a common audio reference that works with unprecedented accuracy across different locations, devices and operators. We want to liberate music creators from monitoring translation issues so they can focus on musical decisions rather than working around the physical limitations of their room and gear.’

The Sonarworks SR standard is comprised of patented sound measurement technology and professional grade signal processing. The result is accuracy (±0.9dB) among different locations, playback devices and users. The standard works equally well on both loudspeakers and headphones, and is simple to set-up. Starting with the latest update to Reference 4, Sonarworks SR will be included in all of Sonarworks software products.

Sonarworks SR also employs an innovative speaker measurement methodology that captures sound from 37 data-source points – which was determined by Sonarworks researchers to be the optimal point count providing accuracy and measurement repeatability.
