Bandmixr

Bandmixr takes the part of music production that most independent artists find hardest — turning raw multitrack recordings into something that stands up next to commercial releases — and automates it. You upload your stems, label each instrument, and pick a genre. Each stem is analysed for level, tone, dynamics and timing before any processing begins, then a custom mix plan is built around what every track needs and how it sits with the others. Frequency clashes between instruments are resolved automatically so nothing fights for the same space, and the engine applies familiar studio processes like EQ, compression, panning, reverb and saturation.

Once the mix is done you can move straight to mastering, which offers three presets: Streaming for platform-optimised loudness, Standard as a balanced middle ground, and Loud for maximum punch. You can also upload a reference track to steer the master toward a sound you like. Artists who already have a finished mix can skip the mixing step entirely and send it in for mastering only. Finished songs download as WAV, FLAC or MP3, ready for Bandcamp, Spotify or anywhere else you release music. Up to 24 stems are supported per project.

Alongside the core mixer, Bandmixr offers two free browser-based utilities that need no account. The Mix Analyzer gives instant feedback on any mix or master, reporting loudness, true peak, clipping, stereo problems and tonal balance, and offers a free 30-second preview of the enhanced version where mastering would help. The Rehearsal Cutter takes a long rehearsal, jam or live recording and splits it into individual songs by detecting the silence between them, working with either multitrack stems or a simple phone recording. The company states that artists retain 100% ownership of their music and that files are never used to train machine-learning models.
