Rapid Flow Drops True AB: Free Mix Referencing Weapon or Hype?

Rapid Flow’s Erik isn’t here to sell snake oil—he’s giving away True AB, a referencing plugin designed to keep your mixes honest. Forget paying €95 for another plugin that just flashes pretty lights. True AB lets you A/B your tracks against real-world references, matches loudness automatically, and even throws in a delta view to show you exactly where your frequency sins lie. The video’s a tour of practical, sweat-proof mix checks—across club rigs, grottboxes, and even that crusty old phone speaker. If you’re chasing pro sound without the pro price tag, this one’s for you.

True AB: The Free Street Weapon

Let’s get this out of the way: True AB is free, and Rapid Flow’s Erik wants you to stop mixing in a bubble. This plugin is built for referencing—A/B your own track against a proper mix, fast, and actually hear the difference before your ears numb out. We’re talking pro-level referencing here, not just flicking between two volume-fudged WAVs.

What sets True AB apart isn’t just the price tag (zero), it’s the way it makes referencing dead easy for the rest of us. Load your track and a reference, flip between them, and boom—your dodgy EQ moves are exposed. Erik’s approach is all about getting your mix closer to release-ready, not just impressing your mates on Discord.

We get used to something sounding a certain way in our room very quickly.

Loudness Matching: No More Cheating

Automatic loudness matching means you’re not fooling yourself. True AB levels your mix and the reference so you’re comparing apples with apples—not apples with a cranked limiter. It’s proper A/B, not a loudness war.


Delta View: Find Your Mix Crimes

This is unique, I don't think I've seen any plug-in do this.

True AB’s spectrum analyzer and delta view aren’t just for looking clever—they actually show you where your mix and your reference part ways. Want to see if your bass is eating up the subs or your highs are missing in action? The delta view paints it in blue and green, so you can’t hide from your own mistakes.

This isn’t just eye candy. It’s a reality check for anyone who thinks their bedroom mix is ready for Berghain. The plugin’s zoom and loop tools let you zero in on tricky sections, revealing whether your hats slap or your kick’s just flopping about. If you want forensic detail, you’ll have to watch the video—some of these visual tricks need to be seen and heard in action.

Mix Checks Across the Rave Jungle

Here’s where Erik gets dirty: club systems, cars, mono grottboxes, ancient nearfields, and even your phone—all modelled, all A/B’d. True AB lets you check your mix as it’ll sound in the wild, not just on your overpriced headphones. The car preset is based on his real motor’s response, so if your bass is blowing out the boot, you’ll know before your Uber driver does.

Whether you’re chasing punch in the club or clarity on a crusty kitchen radio, this plugin’s got you covered. There’s a whole section on referencing low-end with tracks from Stefan Botzin and Jan Blomqvist—choose your target, loop the part, and spot-check until your bass is tight and your vocals actually show up. Don’t expect a step-by-step handhold: the video’s got the gritty details, and some of these tricks are best felt with your own ears.

I went through the trouble of sampling the response of my car.

Referencing: The Only Mix Habit That Matters

Don't underestimate the power of referencing.

Rapid Flow hammers it home—referencing isn’t optional if you want pro results. True AB gives you the tools, the workflow, and the reality check, all for the price of signing up to a newsletter. If you’re not referencing, you’re mixing blind. Erik and crew are basically handing you a club-sized flashlight—don’t sleep on it.
