Reference 4 Measure

The intuitive Reference 4 Measure process uses patent-pending technology to generate a profile of the frequency response of your room and speakers. The step-by-step process takes you through 37 data-source points to create a calibration profile from an array of data.

Once a calibration profile is generated, Reference 4 will correct unwanted or lost frequencies to attain the Studio Reference (SR) sound in your chosen DAW or using Reference 4 Systemwide.

Even in some of the most unruly rooms, a precision of +/- 0.5dB is attained.

Reference 4 Systemwide

As a standalone application, Reference 4 Systemwide becomes a virtual Format-AUdio driver delivering the Sonarworks SR sound. Your system’s Format-AUdio output becomes calibrated based on the headphone profile allowing you to reference your favourite music ahead of a session or enjoy music as it was intended.

Systemwide also features:

  • 2 filter modes: zero latency and phase linear
  • Target curve customization
  • Pre-defined non-flat target curves
  • Mono monitoring
  • Clipping control
  • Dry/Wet control

Reference 4 Plugin

The Reference 4 Plugin will sit at the end of your track, sub or master bus in any application supporting VST, Format-AU, AAX or Format-RTAS plugins. By an average headphone profile, you'll remove unwanted hardware colouration. You can then work with confidence and hear every sound in your mix without leaving your DAW.

The plugin provides features that balances CPU efficiency and filtering latency:

  • 2 filter modes: zero latency and phase linear
  • Target curve customization
  • Pre-defined non-flat target curves
  • Mono monitoring
  • Clipping control
  • Dry/Wet control
