StemLab splits any song into six stems: drums, bass, vocals, guitar, piano, and other instruments.
Slow down difficult passages or speed up for a challenge. Real-time time-stretching that keeps audio sounding natural.
Transpose any song up or down by semitones to match your instrument or vocal range, without affecting tempo.
Isolate any combination of stems. Mute the vocals to sing along, or solo the bass line to learn it note by note.
All processing runs locally on your Mac. Your music never leaves your computer. No internet required.
Export individual stems or custom mixes as high-quality audio files. Perfect for creating backing tracks.
Import any audio file — MP3, WAV, FLAC, AAC, and more. StemLab handles the rest.
StemLab splits your song into six individual stems in under a minute. No internet connection needed.
Solo, mute, adjust volume, change tempo, shift pitch — all in real time. Focus on exactly what you want to learn.
