Reference audio from anywhere



Simply reference from streaming

Meet the new Audiolens desktop app which makes track referencing and comparison easy by analyzing audio from any streaming platform or audio source. Build your personal library of reference tracks that you can access anytime to compare against your own mixes or masters.


How to use Audiolens

If you own Ozone 10 or Neutron 4, Audiolens makes the perfect companion app by sharing your saved reference track tonal profile to the AI Assistants, allowing you to easily match a reference. Match any master with ease.



The lens that listens

The new Audiolens desktop app makes track referencing and comparison easy by analyzing audio from any streaming platform or audio source. Play your chosen audio through the selected output of your device and the application will collect data on key sonic characteristics, helping you to visualize, compare, and match your favorite reference tracks and sounds.


Audiolens listening app UI



Save your faves

Save the tonal data of your references to your Audiolens Target Library to build a personal catalog of reference track data that you can access anytime. Name your tracks so you can quickly find the sounds you want to match, and compare tonal balance profiles with ease. The Target Library talks to Ozone 10 and Neutron 4, automatically populating your references to those plug-ins if you have them.


Ozone 10 Audiolens UI



Match any master

Audiolens will automatically populate saved referenced targets to your Ozone 10 Target Library so you can visualize how your master stacks up to your chosen reference. Run the AI-powered Master Assistant to match the tone, dynamics, and width profiles of the desired track to your own master, and dial in additional adjustments using the Assistant View.




Intelligent mixing, faster

Audiolens will automatically populate saved reference targets to your Neutron 4 Target Library  where they will be analyzed by Neutron’s Assistant. You can then quickly match characteristics within the mix of your own track, whether that’s adding some thump to your bass, crisping up your snare, or making hi-hats sizzle. Further customize your sound by using the Assistant View to dial in your mix elements.


About Referencing

Producers and engineers use track referencing during music production, mixing, and mastering. Referencing is the process of comparing the dynamic range and character of your song to songs of a similar genre and style to your desired sound. A reference track's dynamic range and sonic character can be used to communicate the sound you’re aiming for in your mix or master. Reference tracks are also a way to develop musical vocabulary that will help communication when you're working on a song with other people.
