AIVoiceSeparator vs Vocly

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.

Vocly is an Android app that uses on-device AI to separate phone audio and video into vocal and instrumental tracks. Standard mode separates vocals and instrumental; Advanced mode also separates drums, bass, and other sounds. It accepts MP3, M4A, WAV, FLAC, and OGG audio. The mixer can mute, solo, balance, loop, change tempo from 75–125%, shift pitch by ±6 semitones, and compare with the original. Users can add and synchronize lyrics for karaoke. Imported MP4 or MOV video can be exported with vocals or music while retaining its picture. Audio exports include M4A, WAV, and FLAC, with individual stems or custom mixes. Separations are saved locally, and a batch queue handles multiple files. After a one-time model download, processing works offline. The Free plan costs nothing and includes ads, separation, mixer, karaoke mode, and a stem library. Pro monthly and lifetime plans have prices not listed.
