Open Rehearsal CutterOnline mixing & mastering, answered
Bandmixr is an automatic online mixing and mastering platform built for musicians and bands. Upload your raw stems, choose your genre, and get a professional-sounding mix, all from your browser. Already have your own mix? You can upload it directly for mastering only. Bandmixr is expanding its toolkit with additional tools designed for musicians, like the Rehearsal Cutter.
Upload your individual stems (drums, bass, guitar, vocals, etc.), pick a genre, and Bandmixr takes it from there. Every stem is analyzed individually, and a custom mix plan is built based on what each track needs and how it fits with the rest. Frequency clashes between instruments are resolved automatically so nothing fights for the same space. The result is a balanced, polished mix shaped by your chosen genre.
After your final mix is created, you can apply mastering with one click. Choose between three presets: Streaming (optimized for platforms like Spotify and Apple Music), Standard (a balanced middle ground), or Loud (maximum punch and density). You can also upload a reference track to guide the mastering toward a sound you like. If you already have your own mix, you can skip the mixing step entirely and upload it straight to Bandmixr for mastering only.
Bandmixr currently supports Rock/Indie, Pop, Acoustic, Punk, Metal, Jazz, Blues, Funk/Soul, Reggae/Dub, Hip Hop, and Electronic. If your genre is not listed, choose "General / Not sure" and Bandmixr will apply a balanced, genre-neutral mix.
You can create projects, upload stems, and generate mixes on the Free plan, and your first song download is free. After that, downloads start at $5 per song, or go unlimited with the Creator and Pro plans. The Rehearsal Cutter and the Mix Analyzer are completely free for everyone, with no account needed, since they run entirely in your browser.
Cut individual songs out of long rehearsal or jam session recordings. Drop in hours of audio and the Rehearsal Cutter detects the silence between songs and splits your band practice recording into separate tracks automatically. Works with multitrack stems and simple stereo or phone recordings. Everything runs locally: Your files never leave your device.
You do 100%, always. Bandmixr claims zero rights to your stems, mixes, or masters. There is no licensing, no usage clause, and no transfer of ownership. Your music is your intellectual property, and using our tools does not change that in any way. We never share or sell your files, and never use them to train machine-learning models. When you delete a file, it is permanently removed from our servers.
