In their own words
Fadr
Fadr is a music tool for separating vocals and 15 other instruments from songs, making remixes and DJ sets, and creating instruments and drum kits with AI. Fadr Basic offers unlimited stems, remixes, and DJ sets, with high-quality MP3 downloads; song uploads on Basic are limited to 10 minutes. Fadr Plus provides 18 stem types, uploads up to one hour, WAV downloads, plugins, API access, and unlimited storage for $10/mo.
Siren makes playable instruments from words and provides ADSR controls and low-pass, high-pass, band-pass, and notch filters. DrumGPT creates 16-element drum kits from text prompts, with pitch, volume, and amplitude-envelope controls. The Stems Plugin works with major DAWs and other software that supports VST3, with Windows VST3 and Mac VST3/AU support. Siren is available online, as an iPhone and iPad app, and as an audio plugin. The API separates songs into vocals, drums, bass, melodies, and instrumental, and detects MIDI, chords, key, and tempo. API use requires Fadr Plus; its Create Stem Task endpoint costs US$0.05 per minute of audio.
Ultimate Vocal Remover
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.
