AIVoiceSeparator separates songs into vocal and instrumental stems for backing tracks or clean vocals. Its Studio pipeline combines BS-Roformer, Mel-Roformer, and MDX23C models, followed by EBU-R128 loudness normalization. The maker reports an SDR of 12.97 dB and says that is about 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 are accepted; TikTok clips must be saved and uploaded. Optional Whisper transcription produces SRT, LRC, and TXT files and adds about 30 seconds to processing. Its REST API accepts a URL or file and returns both stems. The free plan provides three songs per month for signed-in users. Credits cost $0.50 per purchase, while Pro is $30.00 per month. The maker says audio is processed on its own GPU in Thailand, deleted within 24 hours, and not used to train AI models.
