VST3 / AU — Windows 10+ & macOS 11+
Early-access price · One-time purchase · Lifetime updates
Why $69? Perceived Loudness is in early access. A far more advanced perceptual-loudness model is on the way (planned for 2026), and at full launch the price rises to $149. Buy now and you lock in free lifetime updates — including that release. Early adopters never pay the difference.

Is this a subscription?
No. Perceived Loudness is a one-time purchase with a lifetime license. You pay once and own it forever — with free lifetime updates, from bug fixes and OS-compatibility patches all the way up to major engine releases.
What does “early access” mean?
The plug-in you get today is complete and fully functional — every meter listed above works right now. Behind the scenes we’re training a next-generation perceptual-loudness model, planned for 2026. When it ships, the price rises to $149 — but early-access owners receive it as a free update, like every update after it.
Which DAWs are supported?
The plug-in supports VST3 on Windows and VST3 + AU on macOS, compatible with major DAWs including Ableton Live, Logic Pro, FL Studio, Cubase, Studio One, Reaper, and more.
What is the refund policy?
Perceived Loudness includes a 14-day free trial, so you can fully evaluate it before buying. You can request a refund within 14 days of purchase; once a license is activated the sale is final, except if the product is faulty or not as described. All payments are processed by Paddle (paddle.net). See our Refund Policy for details.
Are there any discounts?
We occasionally run a listening-test event that rewards participants with a discount code. There’s no active event right now — stay tuned for the next round.
Does it replace my existing metering plug-in?
Yes. Perceived Loudness includes all standard metering (VU, LUFS, True Peak, LRA) plus exclusive PLFS and PLD analysis. It covers everything a typical meter does and goes further.
What is PLFS?
PLFS (Perceptual Loudness Full Scale) is a perceptual loudness metric designed to better reflect how loud a mix actually feels to the human ear, going beyond traditional LUFS measurement.
