AIVoiceSeparator vs VocalDrop

AIVoiceSeparator separates songs into vocal and instrumental stems for backing tracks or clean vocals. Its Studio pipeline combines BS-Roformer, Mel-Roformer, and MDX23C, then applies EBU-R128 loudness normalization. The maker reports an SDR of 12.97 dB and says this is roughly 3 dB above the open Demucs baseline. The web app accepts audio and video files up to 100 MB and 20 minutes in formats including MP3, WAV, M4A, FLAC, OGG, WebM, Opus, and MP4/MOV. You can submit YouTube or SoundCloud links; TikTok clips must be saved and uploaded. Optional Whisper transcription returns SRT, LRC, and TXT files and adds about 30 seconds to processing. A REST API accepts a URL or upload and returns both stems. The free plan allows three songs per month when signed in; pay-as-you-go credits cost $0.50. The maker says uploads and results are deleted within 24 hours and audio is not used to train AI models.

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.
