Vocal Remover

About Vocal Remover

Turn audio or video you already have into useful music-practice and editing files, directly on your Android device.

Vocal Remover can create:
• Two stems: vocals and instrumental
• Four stems: vocals, drums, bass, and other
• Six stems: vocals, drums, bass, guitar, piano, and other
• Karaoke and acapella tracks
• Custom mixes from synchronized stems
• Automatically generated, timestamped lyrics

Work with every stem
Open Stem Studio to play all stems from one synchronized native mixer. Mute or solo tracks, change each stem's volume and stereo balance, set master volume, seek accurately, change playback speed, and loop a selected section. Save the mix preset, export a WAV mix, or package stems and lyrics in a ZIP file.

Create editable lyrics locally
Lyrics are transcribed from the isolated vocal track—not from an online lyrics database. The multilingual model detects the likely language and creates timestamps. Edit text and timing, replay or loop lines, split, merge, insert, delete, search, replace, undo, and redo. Export corrected lyrics as TXT, LRC, or SRT. Singing is harder than speech, so results may need correction.

Local-first processing
Audio separation, language detection, transcription, waveform generation, and mixing run on your device after the required open-source model packs are installed. Your selected audio is not uploaded to an Old Alex Hub processing server. No account or subscription is required.

Free features and exports
There are no processing credits, daily audio limits, subscriptions, export watermarks, or paid downloads. The app is supported by ads. Ads never unlock a feature and local work remains available if an ad cannot load.

Model packs
The Essential separation and Lyrics packs install automatically on first launch. The optional Advanced pack enables four- and six-stem processing on capable 64-bit devices. It is much more demanding and may be slow; processing speed depends on the device, file length, and selected mode.

Import and export safely
Choose supported audio or video with Android's document picker or share it to Vocal Remover from another app. Originals are never overwritten. Save outputs to a destination you choose or share WAV stems through Android.

Important limitations
Stem quality varies with the recording, mix, effects, and selected model. Six-stem guitar and piano isolation may be less accurate. Automatically generated lyrics are not official lyrics and may require correction.
