Sonura vs Ultimate Vocal Remover

Sonura is an artist-led AI music studio for making loops, vocals, one-shots, stems, and full tracks in a browser or DAW. Its Sonura Split tool separates an uploaded mixed track into vocals and instrumental, or into six stems: vocals, drums, bass, guitar, piano, and other. It accepts WAV or MP3 uploads and returns stems in either format. Sonura says most tracks finish in under a minute, while longer files and six-stem splits can take a few minutes; processing runs on its machines. The page directs users to check the app for the current file-size limit but does not state the limit. For DAWs, Sonura Flow is a VST3 and AU plugin for Ableton Live, Logic Pro, FL Studio, Studio One, Bitwig, Cubase, Reaper, and GarageBand. It is available for macOS 12 Monterey or later and 64-bit Windows 10 or 11, and needs an internet connection while creating sounds. Sonura says stem splitting is cleared for commercial use if users own or have permission to use the recording. The free plan includes daily creation allowances; paid plans start at $20/mo.

Ultimate Vocal Remover is a free desktop application for separating audio sources and removing vocals from audio files. It uses deep neural network source-separation models and supports batch processing. Exports are available in WAV, FLAC, and MP3, with stem choices including vocals, instrumental, other, bass, drums, guitar, piano, synthesizer, strings, woodwinds, brass, and wind instruments. The project describes itself as fully open source and free to use and modify. Its GUI code uses the MIT license, while developers using the models are asked to credit UVR and its developers. UVR runs on Linux, macOS, and Windows. Windows installation targets Windows 10 or newer and requires the main C: drive. macOS downloads target Big Sur or newer and distinguish Apple Silicon from Intel. Linux instructions cover Debian- and Arch-based systems. FFmpeg handles non-WAV files, and Rubber Band supports time-stretch and pitch-shift tools.
