MixChecker Ultra+: Mix Referencing Tool by Audified

The core of MixChecker Ultra+ is its library of more than 90 device simulations. The list includes industry-standard studio monitors and headphones, laptops, phones and earbuds, car audio, club PA systems and small Bluetooth speakers.

Each device can be adjusted on its own. You can change its volume or set the stereo base of the simulation to better match real listening conditions. The engine also models non-linear behavior, so you can switch on distortion and check whether your mix clips or distorts on a chosen device.

For acoustic context, you can import your own WAV impulse response to hear the mix in a specific room, such as a friend's studio or a large hall.

MixChecker Ultra+ includes a set of analysis modules you can select independently: Loudness, Dynamics, Spectrum, Stereo, Gonio and Player. Each module can be expanded into a larger window for more detail.

The Loudness module includes presets for popular streaming services and shows whether your track exceeds an adjustable threshold. The Dynamics module displays the peak to short-term loudness ratio. The Gonio and Stereo modules help identify issues such as inverted, fully mono or lopsided signals.

The Player module imports a reference track in WAV or MP3 format and compares it with your mix in each module.
