Watch It Find the Gap





Seven Things It Measures. One Word Each.
Under every label on the wheel is a single word saying which way your mix is leaning. Read it as a sentence: your mix is narrower.
Everything You Need to Close the Gap
You decide.
HMD Reference will never tell you your mix is wrong, and it will never tell you what to reach for. Two records can differ enormously and both be finished — a ballad against a programmed-drums record isn't a mistake, it's two different songs.
So it describes the difference, honestly, and stops there. You already know how to fix a mix. This tells you where to look.
Measurement"Your mix has more low-mid weight than the reference." — always true. Never "too much low end."About HMD Reference
HMD Reference
Stop guessing what’s different.
You know the feeling: you pull up a reference record, switch back and forth with your mix, and you can hear that something is different. But figuring out exactly what can turn into an endless guessing game.
HMD Reference was built to solve that.
Load your mix. Load the record you’re chasing. HMD Reference analyzes both and tells you in plain language where they actually differ.
More bass. Less punch. Narrower stereo image. More low mid weight. Smoother upper mids. Whatever the difference is, HMD Reference measures it and puts it into words you can understand.
No grades. No advice. No “your mix is wrong.” It measures. You decide.
Behind the scenes, HMD Reference compares balance, dynamics, punch, stereo image, loudness and more using real DSP running directly on your computer. Your biggest differences are surfaced first, while areas that are already close are shown so you also know where you can stop working. HMD Reference Manual
