Stemora: Stem Splitter Offline

Stem splitter offline on your phone: with Stemora you pick a song and get the vocals and the instrumental as separate tracks, ready to play, mix and export. Use it as a vocal remover for karaoke, a practice tool for musicians, or a quick way to pull a clean vocal out of a mix. The separation runs on your phone, so your songs are not uploaded to split them.

HOW IT WORKS
Open Stemora, choose an audio file from your phone and pick a mode: Vocal remover for two tracks, or 4 stems for vocals, drums, bass and other. The stem splitter AI runs a deep-learning separation model on the device, shows you which section it is working on, and opens the result in the mixer. Every song stays in your library with its stems, mix settings, notes and lyrics, so you can come back to it later.

VOCAL REMOVER FOR KARAOKE
• Remove vocals from songs and keep a clean instrumental backing track
• Keep the isolated vocal to study a melody, learn harmonies or prepare a cover
• Processing shows each stage and its progress, then opens the mixer
• Free: 3 vocal remover splits a day, songs up to 8 minutes
• Need to remove vocals from songs for a party, a rehearsal or a recording session? A free vocal remover for karaoke is the fastest way to get there

FOUR STEMS: VOCALS, DRUMS, BASS, OTHER
The stem splitter AI can also cut a song into four stems: vocals, drums, bass and everything else. Mute the drums to practise with your own kit, solo the bass to work out a line by ear, or drop the vocal to sing along. You can start a 4-stem split from the library or straight from the mixer of a song you already split.

PRACTICE MIXER
• A fader for every stem, plus mute and solo
• Waveforms for each track — tap to jump to any point
• A–B loop to repeat a hard passage until it sits
• Live tempo from 0.5× to 1.5× without changing the pitch
• Key shift of ±6 semitones to fit your voice or tuning
• Notes for lyrics, chords and cues

A good karaoke maker needs more than a missing voice: slow the chorus down, move it into your key, loop the bridge, then sing it at full speed.

EXPORT AND SHARE
• Export the current mix with your levels, tempo and key, or export a single stem
• MP3 and M4A for free; lossless WAV and FLAC with Pro
• Save to Music/Stemora or share to any app

AUDIO TOOLS
• Noise reduction to clean up hiss and hum in a recording
• Tempo & key tool: change speed and pitch independently and save a new file
• BPM finder that reads the tempo of any song

AI LYRICS AND TRANSLATION
Generate the lyrics of a split song and follow them karaoke-style, in sync with playback. Translate them into 9 languages and switch between them with one tap. AI Lyrics is the one feature that uses our server: it sends the vocal stem for transcription and uses AI credits.

HOW TO UNLOCK MORE

WHY MUSICIANS USE IT
Learning a song by ear is easier when you can hear each part on its own. Solo the bass to copy a groove, mute the guitar part you are playing yourself, or take the vocal out and use Stemora as a karaoke maker for your next session. As a vocal remover AI it gives you the instrumental; as a stem splitter AI it gives you the whole band, one instrument at a time.

WHO IT'S FOR
Karaoke singers who need a backing track, cover artists, guitarists, bassists and drummers who learn songs by ear, DJs and producers who want an acapella or an instrumental, and teachers who build practice tracks for students.
