Moises
Moises is an AI-powered music practice and creation platform that has rapidly become one of the most popular audio separation tools in the world. Originally focused on musicians who want to isolate instruments for practice and transcription, it has expanded into a comprehensive music toolkit used by DJs, producers, music educators, and content creators.
The flagship feature is AI audio separation. Users upload any song, and Moises' neural network models decompose it into individual stems — vocals, drums, bass, guitar, piano, strings, and other instruments. The separation quality is among the best available in consumer tools, producing clean stems with minimal artifacts. Unlike simple EQ-based isolation, Moises uses genuine source separation AI that can distinguish overlapping sounds in the frequency spectrum.
For DJs, Moises provides several valuable tools beyond stem separation. The key detection engine identifies the musical key of any track, essential for harmonic mixing. The BPM detection is highly accurate, even with tracks that have tempo fluctuations. The chord detection feature identifies chord progressions in real time, displayed alongside the audio waveform. Smart metronome generates a click track that follows the song's actual tempo, including subtle tempo changes.
The pitch and speed adjustment tools allow users to change the key or tempo of any track (or individual stems) without affecting the other parameter. DJs can use this to create custom edits — changing the key of a track for harmonic compatibility, creating instrumental versions, extracting acapellas for mashups, or adjusting tempo for specific DJ sets.
Moises includes practice features that benefit musician-DJs: loop points for practicing specific sections, a musical notepad for annotations, and integration with various instruments. The social platform allows users to share separated stems and collaborate on projects. Available on iOS, Android, and web, Moises offers a freemium model with a generous free tier (limited separations per month) and a premium subscription that unlocks unlimited separations, higher quality processing, and additional features.
