What counts as a choir

A choir is a group of singers performing together, usually in parts. Think of a gospel choir behind a soloist, a church or school choir, the wall of voices in a film cue, or a big layered "ahh" pad in a pop song. The model is trained to find that group sound and separate it from everything else.

A single singer with a few backing vocals is not really a choir. For that, use Separate Lead and Backing Vocals.

Who uses it

Choir singers and directors hear their own section against the rest by pulling the choir out and playing along. Film and game composers study how a layered choir is arranged in a cue they admire. Producers sample a choir swell to drop into a new track. Video editors remove the choir from a piece of music so dialogue can sit on top.

What works well, and what leaves traces

Choirs are a hard target because they sit in the same range as lead vocals and strings. A choir singing alone with an orchestra or organ usually works well. A choir that has a lead soloist in the same range may leave bits of the soloist in the Choir file. Dense orchestral cues can leave some string sound with the choir. Heavy reverb, common in churches, adds a tail that may stay in both files.

Once you have the Choir file, you can split it into parts with the SATB Splitter. If you want every voice gone from the song, use the Vocal Remover.
