ABSOLUTE ZERO

Now in Beta — Free to use. Serious limiting tools shouldn't require serious money.

Get dual-pass processing, multiband control, and lab-grade visualization and metering at a price that doesn't exist elsewhere.

Build exactly the chain your material needs. Four algorithms per pass. Instant or windowed detection. Multiband mode. Soft safety. Hard safety. In isolation or all together.

WHAT IS ABSOLUTE ZERO?

A modular limiter designed for research and real-world production. Achieve deep gain reduction while preserving clarity and musicality.

Dual-Sidechain Processing: Two independent sidechains analyze the signal in parallel—Pass 1 computes main gain reduction, Pass 2 analyzes post-reduction and applies secondary limiting.

Get the analytical benefits of cascaded limiting—without the cumulative artifacts and phase shifts.

SEE WHAT YOU HEAR

Absolute Zero exposes the signal processing visually—so you can link what you hear to what you see.

Eight independent metering windows, each available as standalone windows you can dock anywhere on your screen.

The embedded limiting test confirms your limiter is actually limiting—watch how envelope and lookahead settings shape the output waveform.

Dual ITU-R BS.1770 loudness meters with delta display show the difference between input and output in real-time.

MORE COMING SOON
We're finishing ARIA first. After that, we'll add:

The four algorithms — what each one does and when to use it

Multiband mode — four bands, five reconstruction methods, tone balance

Detection modes — instant vs. windowed, same algorithm, different feel

Safety stages — soft catches overshoots, hard guarantees the ceiling

Transparent parameters — what you're actually controlling

Curve editor — draw your own threshold-to-drive mapping

Preset system — full state, per-algorithm, dual-sync

Verification tools — how we prove limiting works before trusting it

Who it's for — mastering, mixing, broadcast, research

Roadmap — Input Adaptive Gain, mobile, AAX, more algorithms

Until then: User Manual — or just download and try the beta.
