Under the hood

Everything technical stays in the background.

You never leave the song to tend to the tool. But for anyone who wants to know, every promise here is something the app measures and does to the signal, not a word we use.

YOUR ACTUAL ROOM · THE WHOLE STORY

The reverb is your real room, measured, not a preset pretending.

Before anything else, the app listens: it plays an exponential sine sweep through the speaker, records it back, and deconvolves the result to recover your room’s real impulse response — decay time from Schroeder backward integration, early reflections from peak-picking.

MEASURED IMPULSE RESPONSE

0 msyour room · RT601.8 s

Sample-locked timing

Part eight, as tight as part one.

Every track is captured against one shared clock and stamped at the instant of capture. A loopback test measures the app’s own round-trip latency and compensates to the fractional sample.

Clean at any depth

Stack eight parts, keep one honest floor.

One read of the room’s noise floor drives both the gate and the reverb fill, and cleanup runs once on the master sum, never per track.

One shared space

Every part lives in the same room.

All tracks feed a single, globally-excited ambience bed instead of each carrying its own mismatched tail. The reverb send is taken pre-gate, never post.

Capture-quality alerts

It warns you before a take is wasted.

A capture-quality classifier flags each input green, amber, or red, surfacing a flaky Bluetooth mic or a bad route up front.

The whole path runs on AVAudioEngine with no third-party audio dependencies, which is what lets every one of these promises actually hold.
