The final pass before release.

Drop a WAV. Hear what's actually harsh. Clean the sheen, try a mood, level the album — then export a file you'd be willing to put your name on.

See it

Sheen score, problem regions, and frequency lanes so "too bright" has a location. Band Solo lets you loop a range and hear one lane in isolation.

Try it

Loop a selection. Clean only the air. A/B at matched loudness. Commit when it earns it.

Ship it

Print a WAV. Match album levels. Queue the rest of the EP.

What LaunchTone is

Release-prep for finished stereo WAVs
On-device analysis and processing
A producer-style second opinion (Fresh Ears)
Selection-based cleaning and named moods
Album loudness planning and batch queue

What it isn't

Not a DAW — no MIDI, plugins, or multi-track mixing
Not cloud mastering — your file stays on your Mac
Not a music generator
Not iOS or Windows (macOS only for 1.0)
Not MP3/AAC ingest in 1.0 — WAV only

Built for the last listen

The session is closed and the WAV is sitting on your desktop — bright, a little glassy, not quite ready for the world. LaunchTone is for that moment.

Sheen Cleaner

Maps glassy, fizzy high-frequency artifacts and lets you try a clean on a loop — or only on Presence, Brilliance, or Air — before you print the full track.

Fresh Ears

A second opinion on your mix. Recommended treatments, optional ideas, and a clear list of what to leave alone. Sometimes the honest move is to do nothing.

Mood Maker

Polish, Character, or Warp. Named mix treatments you can apply to the whole song, a highlighted moment, or a single frequency band.

Track Leveler

Measure your album together, propose who should come up or down, and export with a true-peak ceiling so the record feels like one record.

Band Solo

Loop a range and hear one frequency lane in isolation — the fastest way to confirm where a problem actually lives before you fix it.

Track Editor

Split, fade, move, and EQ without reopening the DAW. Graphic EQ with labeled frequency ranges for the trims that shouldn't require a full session.

Join the closed beta

FAQ

Is this AI mastering?: No. LaunchTone analyzes your WAV on your Mac and applies DSP you can A/B. It does not upload your master to a cloud engine and it does not generate music.
Do I need a DAW?: Not for LaunchTone. You need a finished WAV.
What files does it accept?: WAV. Stereo or mono.
Does my audio leave my computer?: Core processing is on-device. Your file stays on your Mac.
