Create a song

Describe the vibe, add lyrics if you want vocals, and Stem Cloud writes the whole song with ACE-Step 1.5.

Try something

Songs are generated by ACE-Step 1.5. If the music model can’t be reached, Stem Cloud falls back to a simple in-browser instrumental.

Stem separation

Drop a stereo song to split it into a vocal-forward centre, an instrumental and a low-end stem.

Quick split works from the centre channel, so it’s best for karaoke and acapella passes. Studio-quality six-stem separation needs a provider such as Music AI.

Audio to MIDI

Drop a melody, bass line or vocal. Stem Cloud tracks the pitch and gives you a MIDI file.

Links use ?ref=code. They only carry the code once Stem Cloud is on your own domain, because this preview address drops anything after the “?”.

Vocal lab

Record or upload a vocal, then shape it with studio effects and creative tools.

No vocal loaded yet. Only the first 60 seconds are processed.

Advanced vocal creativity

Switch on any mix of tools, adjust them, then create. Quick starts:

Text to robot voice

This plays through your speakers. Browsers don’t let a page record it into the Library.

Cloud AI vocals

These need a hosted AI model and a backend, so they aren’t live yet. Once the backend exists, they plug in here.

Music video maker

Drop a song and Stem Cloud makes a video that moves to the music.

Add a song to begin.

The video is recorded live while the song plays, so it takes as long as the song. Keep this tab open and visible until it finishes. The visuals react to your music; they aren’t AI-generated scenes.

BPM and key finder

Drop a song or loop and Stem Cloud tells you its tempo and musical key.

Drop a sound hereor click to browse · WAV, MP3, OGG, FLAC, M4A

Works best on a full mix or a melodic loop. Drum-only sounds have no key, and tempo needs a steady beat. Only the first 90 seconds are analyzed.

Studio

Record, import and mix up to 8 tracks. Everything stays in your browser until you export.

0:00.0

Recording starts at the playhead, so you can layer new takes over what’s already playing. Click a waveform to move the playhead. Use headphones to avoid feedback.
