Import the song
Drop in an MP3, WAV, FLAC or M4A — or a video, whose audio track is pulled out first. Nothing is uploaded.
Five-stem separation
A finished mix is one file. Jambox opens it into the five parts a band is made of — vocals, guitar, piano, drums and bass — on your own computer, so you can hear the part you are learning and drop the rest.

The model splits it
Five stems come back with their own faders, names and waveforms, each one soloable and mutable on its own.
Play against them
Mute the guitar and play it yourself, or solo the vocals to learn the melody. Every stem can be exported as a file.
What you get
- Five stems: vocals, guitar, piano, drums and bass
- A WAV of the whole mix, or a ZIP of every track
- Chords, key and tempo read from the same analysis
Where it stops
Separation is limited by the song length your machine can hold in memory — five minutes on an 8 GB laptop, up to eleven on a 16 GB desktop. The model runs locally, so the work is your own CPU’s.
Questions
Is the song uploaded anywhere?
No. The file stays on your computer; the only thing that ever reaches a server is your account, never the audio.
Which formats can I import?
MP3, WAV, FLAC, M4A, AAC, OGG, OPUS and AIFF, plus video files — a video contributes its audio track and nothing else.
Can I keep the stems?
Yes. The menu on any song exports every track into a folder named after the song, as WAV files.

Chord recognition
JamAI, our own chord engine, transcribes the progression and shows it in sync with the song.
Key detection
The analysis works out which key the song is in and prints it — “detected: A minor”, the line the app shows under its transpose slider. That reading is the zero point: the song opens in its own key, and every semitone you shift is counted from there.
Key-change detection
When a song moves to a new key, the analysis finds the bar where the tonality changes and raises a gold flag on the chord track, with the new key written on it. The place your chart stopped making sense is the place you can see.
