True AB Referencing helps you hear how your track stacks up against released music, so you know what needs adjusting before it leaves your studio.
For the first five years of my career, I underestimated A/B referencing. Then I took my laptop to a club where I used to DJ and played my unfinished track beside a released record. I immediately heard differences I’d been missing in the studio.
That experience showed me why referencing matters. We made flow AB referencing so you can make those comparisons inside your own session and hear what needs work, whatever setup you’re mixing on.
Erik Heirman, Founder of Rapid Flow
Switch between your mix and a finished reference to hear the difference immediately. True AB referencing brings the reference down to your track’s level, so extra loudness won’t skew your judgment.
Start with the club system model and compare your track’s low-end weight with a released reference. Then explore the other playback models to hear which details stay clear and where the balance changes, while you can still make adjustments in your session.
True AB lets you check what weakens in mono and listen to the side signal for low-end clutter in wide reverbs. Hear where the problem is before deciding what to change.
Expand the spectrum to inspect the frequency balance, check your loudness and peaks, or listen to the side signal for low-end clutter in wide effects. Give your next adjustment a clear reason.
Mixing without a reference
Mixing with True AB
Choose the view that keeps your session easy to follow. Switch between Light and Dark themes to suit your workspace, and expand the spectrum when you need a closer look at your mix’s frequency balance.

True AB by Rapid Flow has quickly replaced my previous EQ reference plugin. It outperforms other market leaders thanks to several standout features: • Real-time visual feedback for both active and reference tracks • Seamless level matching • Delta monitoring • Support for up to 5 reference tracks simultaneously
Brock P. 5/5 Verified
It's awesome, autogain is a bit finicky, maybe add different modes? Like one for, peak, rms, etc, some filtering options - being able to hone in on any part of the spectrum, compare lows, high mids etc, stereo image, correlation and dynamics would be great, also different slope options, I prefer 4.5, and optimised sync...
Byron T. 5/5 Verified
It’s a great tool; I also have Melda MCompare—that one is just as good, plus it has a spectrum analyzer. Thanks a lot!
Vasya S. 5/5 Verified
Very useful tool to see in What frequencies I should revise.
Rodrigo M. 5/5 Verified
I've been loving this product so much since I got it. It's very straightforward to use, and the auto-gain compensation makes comparing my mix with my reference track such a breeze. I love how intuitive the plugin is to use!

True AB became essential to me in no time. It offers what metric ab is still missing.
Mccdusk 5/5 Verified
Truthfully, I have only used it on 3 projects that I am currently working on, but am seeing a big benefit so far. It is very promising given the fact that even though it is rough drafts that I have used it on, my car test is pretty spot on,so far.
Sebastian R. 5/5 Verified
Not yet in reference stage but the layout and flexibility is very good.
Phil L. 5/5 Verified

True A B plug-in is amazing. Super helpful to make your mixes sound like pros. Thanks to the Rapidflow team for making this tool available for free.
Emrah Ö. 5/5 Verified
i think this is great tool. but maybe this tool need one more feature like ability to show the width by frequency band or show dunamics by frequency band. forgive me for my english is not my native language.
Tim K. 5/5 Verified
It's nice to have an alternative to the old industry standard, metric AB. It was even cooler of Rapid Flow to give this out as a freebie to folks! Thanks guys!
Adam R. 5/5 Verified
Looks great but still trying to figure it out. A tutorial for beginners would be greatly appreciated.

Mitsuhiko Y. 5/5 Verified
It's everything one could wish for in a referencing A-B plugin!. I must be honest ! I am new to referencing and comparing my mixes with pro mixes, but it is so intuitive and easy to do that I now use it all the time. I now feel more confident with my musical output!! Thanks for a great tool!! And it was free!! ;-)))
