Demixr vs VocalDrop

Demixr is a web service for processing audio, with tools for separating vocals and instruments, removing reverb, marking speech, and analyzing BPM and key. Its Pro 1.5 vocal separation has Voice mode for complex mixes, live recordings, or speech over music, and Music mode for songs and covers or separating vocals from accompaniment. A separate stem tool uses Demucs to split music into vocals, drums, bass, and other parts. For dereverb, Demixr recommends isolating vocals first; applying the effect to a mixed track can cause artifacts or distortion. VAD provides editable speech-segment markers and batch export, though detection may be inaccurate with quiet vocals or noisy recordings. BPM analysis includes tempo, key, and Camelot values, with optional tap-to-sync. The free plan costs nothing and includes 10 minutes of audio monthly, a 10 MB upload limit, two VAD uses, queued processing, and no WAV downloads. Paid one-time plans start at $4/mo, without automatic renewal. Uploads and outputs are deleted within 24 hours by default.

VocalDrop is a free desktop app that uses AI to separate vocals from songs stored on a computer. A separation can produce both an isolated vocal and an instrumental stem, for uses such as sampling, remixing, editing, or karaoke. Fast and Max modes use RoFormer-family models, with different models available for some hardware. The app can also extract audio from video, separate it, and place a selected stem back into a synchronized video. Users can paste links from YouTube, SoundCloud, Vimeo, TikTok, and more than a thousand other sites for fetching. Optional processing includes denoising, AI vocal restoration, silence removal, and audio-format conversion. The maker says track contents are processed locally and not uploaded. Separation can run offline after the required model download; enabling NVIDIA acceleration also downloads a one-time CUDA package. A command-line interface with JSON output supports pipelines. VocalDrop runs on Linux, macOS, and Windows, and its free plan lists no track limits, watermark, account requirement, or feature paywall. The maker says current builds are not code-signed or notarized and provides SHA-256 checksums for release assets.
