MVSEP vs Ultimate Vocal Remover

MVSEP separates audio into voice and music parts and offers tools for vocal removal, karaoke creation, and stem splitting. Its extraction options include vocals, instrumental, bass, drums, piano, guitar, and other listed stem types; it also provides speech isolation, noise and reverb removal, and audio upscaling. The service lists more than 100 AI models for vocals, instruments, speech processing, transcription, MIDI extraction, and voice generation. It is available on the web, Android, iOS, and Windows, as well as through an API for creating separations, retrieving results, checking algorithms and queue information, managing users, and accessing separation history. Exports include MP3, WAV, FLAC, and M4A, and batch processing is available. The free Unregistered and Registered plans each allow 50 daily separations, tracks up to 10 minutes and 100 MB, and one concurrent job. Registered users also get additional output formats, medium queue priority, no captcha, and limited API access. Premium uses prepaid credits, supports tracks up to 100 minutes and 1000 MB, and offers full API access. Standard models charge by audio minutes; Ensemble models multiply minutes, and every job costs at least one credit.

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.
