How to separate a choir into its parts

A singer learning the alto line wants to hear the alto line, and a recording of a choir gives them all four parts at once. Choir separation turns that recording into a track per part, so one section can be soloed, turned up against the rest, or muted to sing against.

  1. Add your recording: Drop a WAV, AIFF, MP3, M4A, FLAC or OGG of the choir. With an accompaniment, the voices are separated from it first.
  2. Choose the number of parts: Four for SATB, up to eight for divided sections. Say whether the file is the choir alone or has an accompaniment.
  3. Download the parts: Each part as its own file, in time with the others, fifteen seconds a pass. Play one to rehearse it, or all but one to sing against.

Questions about the choir separator?

We have answers.

Can I separate a choir recording into SATB?

Yes. Choose four voices and the recording comes back as four tracks, one per part, in time with each other.

How many parts can it separate?

Two to eight, so a divided choir with two soprano and two bass lines can be split as well as a plain four-part one.

How long a passage can it split?

Fifteen seconds a pass, today. A longer file comes back as its first fifteen seconds, and the tool says so. For a whole song, run it a passage at a time: trim to the chorus or the phrase you want and drop that.

Is it free?

Yes, to start. A free account comes with 120 credits a month and separating a song is 20, with no card needed to start. Pro has 2,000 a month.

Can I get sheet music for each part?

Yes. A choir can be transcribed as an ensemble, one part per voice, and engraved as a score with a stave for each.

Does it work with piano or organ accompaniment?

Yes. Separate the voices from the accompaniment first, then split the vocal stem into parts.

  • A part is a line of notes, so the split starts there

    Four sections of human voices do not differ in timbre the way a trumpet differs from a cello. What tells them apart is what they sing. The recording is transcribed first into a chart with one line per part, and the separator is then steered by that chart, one mask per line.

  • Rehearsal tracks from a performance

    The usual way to get a rehearsal track is to have someone play each part on a piano. A separated recording gives you the part as it was sung, with the words, the phrasing and the breaths, in time with the full choir so that you can bring the rest back in whenever you like.

  • Rooms, unisons and big sections

    Choirs are recorded from a distance in reverberant rooms, and reverb smears every part into the others, so a close, dry recording separates better than a cathedral. When sections sing in unison there is one line to find, and they come back together. The split is by part, not by singer: thirty sopranos are one track.
