Stem Capture

Stem Capture is an AI stem separation app that splits a song into vocals, drums, bass, and other instruments. It also automatically detects the BPM (tempo) and generates a metronome (click track) — perfect for music practice, transcription, karaoke, and remixing.

All processing runs entirely on your device. Your audio is never sent to external servers, so it works offline and keeps your privacy safe.

■ Key features
• AI stem separation: split a song into 4 tracks — vocals / drums / bass / other
• Mixer: adjust volume and mute each part (remove or isolate a specific part)
• BPM detection & click track: detect tempo automatically; adjust BPM and start position manually
• Tempo / pitch control: change speed without changing pitch, or shift the key up/down
• A-B loop: repeat the section you want to practice
• Record & import: microphone recording, capturing audio from other apps, and importing WAV / MP3 / M4A
• History: save separated songs and play them later

■ Great for
• Removing or isolating a specific part for instrument practice
• Removing vocals to create a karaoke track
• Practicing drums along with a click
• Transcribing or arranging music by ear

■ Privacy
Audio and files are processed and stored only on your device and are never transmitted externally. No ads, no tracking.

■ Premium
Core features are free. An in-app purchase (one-time) expands limits such as the number of saved history items.

* Due to advanced AI processing, separation may take some time depending on your device's performance.
