This Sonarworks SoundID Reference for Headphones is both a standalone app and a plug-in that works in your DAW. Suitable for use by audio engineers, producers, musicians, DJs, composers, sound designers, game developers, and audiophiles, it provides you with speaker and headphone calibration. This app / plug-in measures the listening environment and creates a calibration profile to create a consistent listening experience from the inconsistent frequency-response curvers of different headphones. This software runs on Windows and Mac systems.
