Instrument separator

How to isolate an instrument from a recording

Six stems are built for a band. A big band, a string quartet or an orchestra is mostly "other" to them. The instrument separator is a bank of 25 extractors, one per instrument or family, and you can either name the ones you want or let it listen and return whatever is there.

1. Add your recording: Drop a WAV, AIFF, MP3, M4A, FLAC or OGG.
2. Pick the instruments: Tick the ones you want from the 25. Each is pulled out by its own extractor.
3. Take the tracks: One track per instrument, in time with the recording. Export them, or transcribe each into its own part.

The 25 extractors

Each is its own model, trained to pull one instrument or one family out of a mix.

An instrument with no extractor of its own is heard through the nearest one: timpani comes out with percussion, a celesta or harpsichord with piano, a piccolo with flute, an English horn with oboe. Both violin sections of an orchestra come out as one violin track.

• Name it, or let it listen

  Custom takes the instruments you name and extracts exactly those. Orchestra runs the whole bank behind a presence gate, which decides what is actually playing before anything is returned, so a recording with no harp does not come back with a silent harp track.

• Sections and single instruments

  Brass, woodwinds and strings each exist twice: as a section, and as the instruments inside it. Ask for brass and the horns come back together; ask for trumpet and trombone and they come back apart. When several players share one instrument, a voice split deals that track into chairs.

• Priced by how much you ask for

  Each extractor is a model that has to run, so a wide request costs more than a narrow one: the price rises with the number of instruments and is shown before the run starts. Asking for the two instruments you need is cheaper and faster than asking for everything.
