What is Reference+

Headphones are now the most common monitoring tool — not only at home, but also for professionals working in untreated rooms or while traveling. Yet every pair has its own frequency response and tonal coloring that can significantly influence how you perceive your sound — and therefore your entire mix. That’s why we’ve added a completely new layer to MixChecker ULTRA: Headphone Compensation.

For the first time, you’ll hear your mix as it truly is — not as your headphones color it.

Even professional studio headphones are far from flat — some exaggerate the lows, others dip the mids, and many boost the 8–10 kHz range to “please your ears.” If your monitoring reference isn’t accurate, you may end up compensating for the flaws of your headphones — not the flaws of your mix.

With the new compensation layer:

Your headphones are corrected toward a flat or ideal target curve
Your mix decisions become more reliable and consistent
Translation issues across devices are significantly reduced
You can truly trust what you’re hearing — even before engaging any emulations
1. Open Headphone Compensation from the top-left toolbar to access the new overlay.
2. Select your headphones from a list of supported models — profiles are carefully measured for precise correction curves.
3. Choose your target mode:
FLAT — pure correction toward a neutral, reference-flat response
PERFECT — an idealized target curve for natural, balanced listening
CUSTOM EQ — create your own correction curve (and you can combine it with either target)
4. Mix on a corrected foundation — the compensation affects the entire output, so all device simulations and reference tracks are heard on a neutral baseline.
This new compensation layer turns MixChecker ULTRA+ into an even more powerful monitoring ecosystem — removing the guesswork, eliminating uncertainty, and giving you back total control.

Super-realistic device simulations

Choose from 90+ device simulations of the most famous and popular audio devices. Includes up-to-date consumer devices such as laptops, phones, or earbuds. Try the sound profile of the industry-standard studio monitors and headphones. Check how your mix translates in cars, club PAs’, or small Bluetooth speakers. You also have the ability to check your mixes in real-world noisy environments such as subways, noisy streets, shopping malls, and others.

IR loader

With MixChecker Ultra, you can import your custom Impulse Response. You can check how your mix would sound in popular acoustic spaces, your friend’s studio, or even a cathedral. (Supports standard WAV IR files)

Advanced device controls

To understand better how your mix translates on the devices, easily adjust the settings of each device. Adjust the volume of each device independently or set the simulation stereo base to match the real-world conditions better. Our engine also considers the non-linear behavior of the devices and simulates their distortion and clipping. You can easily turn on the distortion and see if your mix would clip or distort on the selected devices.

Analytical tools

Enhance your mix with MixChecker Ultra’s analytical tools. Quickly assess key track parameters using the Loudness Meter, Dynamics Meter, Spectral Analysis, Stereo Analysis, and Gonio Meter. Compare your track’s values with a reference track using the included Player module.

6 different modules

Each module can be selected independently from the selection window. You can also expand each module to a bigger window to see more details on the analysis.

Crucial parameters
of your mix

Loudness

Check how loud your track is and easily see whether you are going over an adjustable threshold. The loudness module includes presets for the most popular streaming services that set the threshold to their level and help you see whether your track would fit their criteria 

Dynamics

Check the dynamic range of your track to quickly see the difference between the loudest and the quietest parts. (Displaying the PSR (peak to short-term loudness ratio) – the difference between the short-term loudness and the maximum true peak value measured in windows of three seconds.)

Spectrum

Quickly see the frequency spectral analysis of your track and compare it to the reference track. This gives you a quick overview of which frequencies you need to focus on to improve your track.

Gonio

Discover the stereo image of your track and compare how balanced your mix is. With this module, you can also easily identify errors in your track, such as a signal that is inverted, fully mono, or slightly angled towards one side.

Stereo

Find out how occupied the frequencies of your mix are in the stereo field. You can then identify whether some crucial frequencies are only present on one side of the spectrum. 

Player

This is a core module of MixChecker Ultra+. You can import a reference track you like and quickly compare your track with the reference in each module. This speeds up your workflow and helps you identify areas to improve your mix. (Supports WAV and MP3 formats)

the legacy of
mixchecker

2015

MixChecker was first introduced in 2015, and the idea came from the big music and TV studios, where the need to reference your mixes on different devices to save time was life-changing. MixChecker was part of the Audified portfolio for years, sold over 15 000 copies worldwide, and is currently available through our partners such as PluginBoutique or Landr.

2017

The big brother, MixChecker Pro, came from us expanding on the idea and pushing it further. Introduced in 2017, it added 50+ new devices, additional features, saveable presets, and many others. Since its introduction, it has sold more than 20,000 copies worldwide and helps our users improve their referencing game every day. This was, is, and will be a staple in the Audified portfolio for many years to come.

2024

And now, MixChecker Ultra is the next step in the evolution of the reference tool game. Driven by customer feedback and the desire to cover more of our customers’ needs in one product, we overhauled and improved everything about the Pro version and then some. With new, up-to-date devices, a new GUI, an improved workflow, and a whole new analytical section, MixChecker Ultra is on the way to becoming the ultimate mastering suite. Many more updates and versions of MixChecker Ultra are coming later, and we are happy to embark on this journey going forward.

2026

The biggest update yet — MixChecker ULTRA: Reference+ — is here. This new version adds the Headphone Compensation layer, a feature that corrects the frequency response of your specific headphones, so you hear your mix as it truly is — before testing it across all the real-world device emulations.

Reference+ continues to provide over 90 listening device emulations, a powerful analytical section, mix-to-reference comparison, and a modern, workflow-focused interface. This update eliminates guesswork, making mix decisions more reliable and consistent across all devices.

With Reference+, MixChecker ULTRA reinforces its position as the ultimate portable studio tool for professionals and enthusiasts alike, and we’re excited to continue evolving it with more features and updates in the future.
