Split a full song into four separate stems, isolating vocals, drums, bass, and other instruments, then mix and record over those tracks on your device. PIONEER SOCIAL MEDIA APPLICATIONS' Android music-radio tool runs its AI locally, so processing and privacy stay on your handset. It pairs a 4-stem separator, one-tap Acapella and Instrumental presets, high-quality exports (WAV, FLAC, M4A), and an integrated video recorder, making it useful for DJs, singers, karaoke fans, and social media creators who need mobile stem editing and performance capture.

What Stem Studio does for creators and performers

Stem Studio splits songs into four stems: vocals, drums, bass, and other instruments, which lets you produce acapellas or backing tracks from existing recordings. The app includes an integrated video recorder that captures performances over custom mixes, so you can record a vocal take with a muted lead, or film a cover while the separated stems play back in sync.

How the app handles formats and exports

The app supports high-quality export formats, including WAV, FLAC, and M4A, so your isolated stems keep lossless or near-lossless fidelity when you save them. Exports come from the on-device processing pipeline, which does the separation locally and then writes the selected file type to storage, enabling downloads in formats commonly used for further production or sharing.

Interface, workflow, and mixing controls

The app offers an advanced stem mixer with per-stem volume control plus mute and solo options, which helps you audition and balance parts before recording. One-tap presets let you switch quickly between Acapella and Instrumental modes, shortening the path from import to performance, while real-time playback and mixing occur directly on the mobile device without routing to external software.

Performance limits and device considerations

All AI processing runs on the device, providing offline operation and avoiding server uploads, but that means the initial AI model must be present on the handset and processing load sits with your device. The app targets Android devices broadly, so actual processing time and responsiveness depend on your hardware, particularly when working with longer or high-resolution audio files.

Good entry point for mobile stem editing with privacy-focused processing

If you want to make karaoke tracks, acapellas, or quick remixes on a phone, Stem Studio offers a practical, privacy-first workflow that keeps audio on-device and combines mixing with a recorder. It suits creators who prioritize local processing and fast toggles between vocal and instrumental modes; note the trade-off that heavy processing is performed by your device rather than offloaded to a server.
