Generate a Backing Track Without Bass
To turn a song into a bass-free backing track, Jamorphosia's algorithm relies on artificial intelligence: it separates the bass from the other instruments, so you can either remove it or isolate it. Everything runs online, with no software to install.
In just a few clicks, generate a backing track from any file (mp3, wav, wma, m4a, mp4), then download it for free. Ideal for locking your groove with the original drums and working on your timing.
You can also do the opposite: isolate the bass on its own to learn a bassline note by note, slow down a tricky passage, or study a bassist's playing. It's your turn to take their place on real songs.
What can you do with a bass-free backing track?
Play your bassline over it
Take the bassist's place on real songs and lock your groove with the original drums — far more musical than a loop.
Isolate or extract the bass
Keep only the bass track to learn a line or analyze its groove note by note.
Download your backing tracks
Get your bass-free tracks for free to play them anywhere, from rehearsal to the stage.
Find your tracks in your library
Keep all the backing tracks you've created on hand, ready to play again.
What quality can you expect?
AI separation delivers excellent results on most well-mixed modern tracks. On some songs (very deep or prominent bass, old recordings) slight residue may remain. To minimize it, start from the highest-quality file possible: a 320 kbps mp3 or a wav gives a better result than an already heavily compressed file.
