Piano Extractor
Separate piano from the rest of the song
Upload a track and Lacuna's AI piano extractor pulls the piano out as its own stem. Solo it to hear chords and voicings, or remove the piano and play the part yourself.
How it works
Turn a mixed song into a focused piano stem
1STEP 1
Upload the song
Add an MP3, WAV, FLAC, AAC, M4A, or OGG file up to 50 MB and 12 minutes.
2STEP 2
Select piano
Piano is already selected. Lacuna separates it from vocals, drums, bass, guitar, and the remaining audio in a six-stem split.
3STEP 3
Preview and export
Solo the piano, compare it with the original mix, or mute it and export a remix without it. Download as MP3 or WAV.
What you get
A piano extractor for the part inside the arrangement
Piano shares its range with guitars, vocals, and pads, so an EQ cannot lift it out. AI source separation estimates the piano part itself and returns it as a stem.
An isolated piano stem
The piano lands on its own track, apart from vocals, drums, bass, and guitar. Chords, inversions, and fills are easier to pick out.
Remove the piano for a backing track
Mute the piano in the mixer and export the remix as a version of the song without it. Play the part yourself over the original band.
Compare with the original mix
Switch between the separated stems and the source recording. Solo or mute any part, and set volume and pan before you export.
MP3 or WAV for the next step
Download the piano stem as MP3 or lossless WAV for your DAW, or take it to MP3 to MIDI and turn the part into editable notes.
Who it's for
Make the harmony easier to hear and work with
The output reflects what the separator identifies as piano in the original recording; overlapping keyboard textures can affect the result.
02
Play-along practice
Remove the piano and play the part against the remaining stems, or keep the original quiet in the mixer as a guide.
03
Producers and arrangers
Take the piano stem into a DAW or an audio-to-MIDI workflow as an editable reference for a remix or a new arrangement.
04
Singers and accompanists
Rehearse with a piano-only version of the song, or with a piano-free version when you supply the accompaniment yourself.

Piano extraction questions
Upload the song, keep piano selected, and start the separation. When it finishes, solo the piano stem in the mixer to check it, then download it as MP3 or WAV.
It returns one piano stem estimated from the finished mix, with the original and other separated stems available for comparison.
Yes. Mute the piano stem in the mixer and use Export remix. The file keeps the vocals, drums, bass, guitar, and other audio, which works as a backing track for piano practice.
Not always. Layered keyboards, processed piano, guitar-like attacks, and dense arrangements can create overlap or place some sound in another stem.
Yes. Download the isolated stem and use the MP3 to MIDI tool. A focused piano stem usually gives transcription a clearer input than the full mix.
You get monthly credits free to start. Each separation shows its estimated credit cost before you run it, and you can top up when you need more.
