Music and audio workflows

Start with what you want to do

Choose a real music or audio task, then follow a focused workflow using the right free or AI-powered tools.

Free workflows for everyday music tasks

Analyze key and tempo, transpose songs and slow down practice tracks with tools that run locally on supported browsers.

Plan harmonic DJ mixes with key, BPM and Camelot code

Analyze your tracks, identify harmonically compatible neighbors and decide where tempo or key adjustment can support a cleaner transition.

Move a song into a key that fits your voice

Transpose a backing track by semitones without changing its tempo, preview the result and compare versions before you export.

Slow down difficult music without changing its pitch

Practice a passage below performance tempo, keep every note in the original key and increase BPM in controlled steps.

AI workflows for audio separation

Use credit-based AI processing when the task requires source separation, such as creating karaoke tracks or extracting stems.

Turn a finished song into a karaoke backing track

Separate the vocal and instrumental, audition the backing track and optionally transpose it into a more comfortable singing key.

Extract a vocal stem for a remix workflow

Separate vocals from the backing mix, inspect exposed phrases and prepare a stem you can align, transpose or process in your production session.

Split a song into practice stems

Hear parts in isolation, mute the part you are learning and build a focused rehearsal mix from a finished song.
