AIVoiceSeparator
What it is
AIVoiceSeparator separates songs into vocal and instrumental stems for backing tracks or clean-vocal use. Its Studio pipeline combines BS-Roformer, Mel-Roformer and MDX23C, then applies EBU-R128 loudness normalization. The maker reports SDR 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, including MP3, WAV, M4A, FLAC, OGG, WebM, Opus and MP4/MOV. YouTube and SoundCloud links can also be submitted; 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 the two stems. The maker says processing runs on its own GPU in Thailand, uploads and results are deleted within 24 hours, and audio is not used to train AI models. Free plan: free, with three songs per month when signed in. Credits start at $0.50, paid once; Pro is $30 a month.
