Bandmixr
ChatGPT pluginMix stems and master songs
Bandmixr mixes and masters music you recorded yourself. It is made for musicians, bands and home producers.
Check a finished song: drop it into the chat and see its loudness, peaks, stereo width and tonal balance with plain-word verdicts, then hear a 30-second mastered preview next to the original. The song is measured in your browser.
Mix your stems: upload the separate tracks of a song (vocals, drums, bass, guitars, keys and so on). Bandmixr recognizes what is on each stem, you check the labels and confirm them with one tap, and the mix and the master then run on their own. Listen to the original, the mix and the master side by side in the chat.
Change the mix in words, for example "vocals a bit louder, less reverb on the guitar, mute the shaker", and Bandmixr makes the mix and the master again. You can also set each stem's volume, mute, reverb and pan in the studio.
Master a finished song in one of three styles: Streaming, Standard or Loud.
Mixing and full-song masters need a Bandmixr account; checking a song does not. Downloads happen on the song's page on bandmixr.com. Bandmixr processes your own recordings: it does not generate music or voices. Supported files: WAV, AIFF, FLAC and MP3.
