Most AI audio tools (LANDR, eMastered) master a finished stereo file. Bandmixr starts one step earlier: it mixes your raw multitrack stems. It balances levels, applies genre aware EQ, compression and panning, resolves frequency clashes between instruments, then masters the result. It's built for bands recording rehearsals and live sets, not for engineers. Plus one free no signup tools that runs fully in your browser.
I play in a band, and like most bands we recorded every rehearsal. Those recordings mostly sat on a hard drive forever, because turning raw stems into something you'd actually share means hours in a DAW or paying an engineer per song.
Bandmixr is my attempt to fix that. You upload your stems, it analyzes each track, balances levels, applies genre aware EQ, compression and panning, resolves frequency clashes between instruments, and masters the result. A few minutes later you have a streaming ready song.
A few things that matter to me:
• There's a free tier, so you can mix a song and judge the result before paying anything.
• One tool is completely free with no signup: a Rehearsal Cutter that splits a 2 hour session into individual songs. It runs entirely in your browser, your audio never leaves your device.
• Your music is never used to train AI.
It's built for bands and home recording musicians, not for engineers.
