Audiola vs StemDeck

Audiola is a free desktop audio studio for Windows, macOS, and Linux. It separates songs into vocals, drums, bass, guitar, piano, and other stems with Demucs running locally, without cloud processing or uploads. The multitrack studio supports cutting, moving, fading, looping, undo history, snapping, and effects. Karaoke view shows lyrics and the original melody, scores singing, and can tune a recorded take toward that melody. Mastering tools provide EQ, compression, EBU R128 loudness targeting, live A/B comparison, and 14 profiles. Users can create local or ElevenLabs voice profiles, swap a clip’s voice, and generate speech from text; the maker advises using only owned or licensed voices. Tracks can be placed in a 7.1.4 spatial bed, which the maker says can be exported. Exports include WAV, MP3, and AAC-M4A. A contact form accepts questions and reports without an account.

StemDeck separates songs into stems for practice, study, transcription, remixing, and other creative audio work. Its Demucs htdemucs_6s model separates vocals, drums, bass, guitar, piano, and other sounds. Files accepted include MP3, WAV, FLAC, OGG/Opus, MP4, and M4A, and songs can also be supplied by YouTube URL. The workspace provides waveform lanes, mute and solo controls, volume adjustment, and looping; users can export individual stems or a custom mix in WAV or MP3. Song analysis includes BPM, key, scale, confidence, integrated LUFS, and sample peak level. StemDeck says audio processing runs locally and the app does not transmit, store, cache, or redistribute audio. Internet access is needed for YouTube downloads and an initial model fetch of about 170 MB, which is cached afterward. The project documents Docker and Unraid deployment, source-based web-server use, and a local REST API. It is free, with no account, quota, uploads, or subscription, but handles one job at a time, supports up to six stems, and has no mobile app.
