Supertone Air 1.0.1 — Mac version

Supertone Air works at three sample rates — 44.1 kHz, 48 kHz and 96 kHz — all inside Pro Tools AudioSuite as an offline processor. It listens to a snippet of reference dialogue, learns its acoustic fingerprint, then stamps that same room tone and tonal colour onto a dry recording. The engine underneath is a neural-network process the developer calls Acoustic Scene Transfer.

• Reverb match on three fronts. Air splits the captured space into direct, early and late reflections. You can pull each fader independently — push the early reflections for presence without washing things out, or pull back the late tail when the original room was too splashy.
• EQ character, not just ambience. The plug-in grabs the tonal imprint of the source recording alongside the reverb. That means the matched result carries the same mic distance, body resonance and high-end roll-off as the reference, not just the echo.
• Profiles you can share. Captured spaces are saved as Air profiles. Export one, hand it to a collaborator on a different machine, and they import it — same match, no re-recording.
• WAV export of the space. Air can render a captured acoustic scene out as a WAV file. Useful if you want to drop the impulse-like capture into a different plug-in or archive it for a later project.
• Offline by design. The plug-in only runs in AudioSuite, so the processing happens offline. That keeps the session responsive while Air does its analysis and rendering in the background.

It is built for Intel and Apple Silicon Macs running macOS 10.13 or later. If you have ever wrestled with matching ADR to location sound by stacking three reverbs and an EQ, Air reduces that to a few clicks.

Mistakes worth avoiding early on

A short reference clip works better than you think. Three or four seconds of clean production dialogue with nobody overlapping is usually enough. Beginners sometimes feed Air a noisy tail or a section where the boom mic moved mid-sentence — the neural network will try to match that, and you get a wobbly result. Pick a moment where the actor is speaking steadily and the room tone is consistent.

The other common slip is leaving the late reflections fader at full tilt on a dry studio booth recording. Air captures the space faithfully, but if the source was a tiled hallway, the tail will sound out of place on a close-miked line. Pull it back until it sits behind the words rather than wrapping around them. Use the proximity control to nudge the sense of distance without altering the reverb character — small moves there stop the matched line from feeling pasted on.

One more: forgetting that Air matches EQ as well as reverb. If you apply it twice — once for space, then a separate EQ match from another plug-in — the tonal curve gets doubled and the dialogue turns boxy. Let Air handle both jobs in one pass, then make gentle trims afterwards if you need to.

AAX, VST3 and AU — it loads in more than just Pro Tools

Does it only work inside Pro Tools? The plug-in ships as AAX, VST3 and AU, so it shows up in Logic, Nuendo, Reaper and other hosts. The AudioSuite workflow is where it feels most at home — offline rendering means no real-time CPU strain — but the VST3 and AU versions let you work in your usual session without switching DAWs.

What sample rates are supported? 44.1 kHz, 48 kHz and 96 kHz. It will not open in a 192 kHz session, so check your project settings before you go hunting for it in the insert list.

Does it need an internet connection for the neural processing? No. All the machine-learning inference runs locally on your machine. Air does not phone home to process audio, and captured profiles stay on your drive.

Ten-second clips finish in a few seconds on Apple Silicon

Processing speed depends on clip length and sample rate, but on an Apple Silicon Mac a ten-second clip at 48 kHz renders in a few seconds — fast enough that you stay in the flow rather than staring at a progress bar. On older Intel machines it is steadier than you might expect for a neural plug-in; the offline design means it does not fight for resources with the rest of your session.

Stability has been uneventful, which is exactly what you want from a tool you reach for during tight deadlines. The 1.0.1 update fixed a naming conflict with another plug-in, and since then there have been no odd crashes or dropped activations worth mentioning. Memory use stays modest because Air loads a profile, analyses the clip and finishes — there is no persistent background process hanging around after the render.

In daily post work, the real win is not having to chain three reverbs and an EQ just to get ADR to sit right. You capture the location space from a reference clip, apply it to the studio line, tweak the decay and damping in one window, and move on. The plug-in's single-minded focus on dialogue means it does not try to be a general-purpose reverb — it does one job and gets out of the way. If you have been looking at Supertone Clear Mac discussions or grabbed a Supertone Air torrent to try before committing, the offline workflow and modest system footprint make it a practical addition to a dialogue editor's toolkit.
