Audiola vs Fadr

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.
