How to remove or isolate the bass in a song

Bass players ask for this in both directions: the song with the bass gone, to play it themselves, and the bass alone, to hear what the player actually did under the band. Both are the same separation, and the bass is one of the stems it gets most right.

  1. Add your song: Drop a WAV, AIFF, MP3, M4A, FLAC or OGG.
  2. The bass is separated: BS-RoFormer splits the mix into bass, drums, vocals, guitar, piano and the rest, each on its own track.
  3. Download both: The song without its bass, mixed in your browser from the other stems, and the bass line alone. Play over the first; learn from the second.

Questions about the bass remover and isolator?

We have answers.

How do I remove the bass from a song?

Drop the song on this page. The song without its bass is the first file in the results.

Can I isolate the bass line to learn it?

Yes. The bass stem is in the results beside the bassless mix, in time with the song. It can also be transcribed, which writes the line out as notes.

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.

Does it work on upright bass?

Yes. Upright and electric both come out in the bass stem, and the instrument separator can isolate a double bass on its own.

  • Why the bass comes away cleanly

    Most of what a bass plays sits below everything else in the band, and it plays one note at a time. That gives a separator less to untangle than a guitar or a piano does. What it shares the bottom with is the kick drum, and that boundary is where a little of one can stay in the other.

  • From the stem to the notes

    An isolated bass line is a single melodic line, which is the case transcription handles best. The stem can be read into MIDI with a pitch tracker that is told which register to listen in, so low notes are not written an octave up.

  • Upright bass in a band or an orchestra

    The six-stem split treats bass as one stem, electric or upright. For jazz and orchestral recordings the instrument separator has a separate double bass head, apart from the cellos above it.
