A conservator’s workflow

Useful restraint, measured in three passes

Generic enhancers hide their choices. Choir Cleanup ties each adjustment to a passage, preserves the source, and writes down exactly what changed.

  1. 01

    Place the sources

    Open the recording and a MusicXML or PDF score map. MusicXML rehearsal marks become editable timing suggestions.

  2. 02

    Rule the passages

    Drag over the waveform, name sections in choir language, and compare source with restrained cleanup.

  3. 03

    Seal the pack

    Confirm rights, then export labeled WAVs, a machine-readable manifest, and a plain-language edit receipt.

A clear boundary

No invented voices.
No black-box “restoration.”

This app uses ordinary, inspectable audio filters: rumble roll-off, a small presence lift, gentle dynamics, optional hum notches, and a soft hiss ceiling.

It does not clone singers, reconstruct lost sound, or promise SATB isolation. It makes an honest rehearsal aid from what is actually on the tape.

Desktop app / private by default

Bring the workbench to the archive.

Runs on macOS, Windows, and Linux. No account is required for the complete import, cleanup, and export workflow.
