MVSEP is an online platform that performs audio source separation and related audio processing tasks using a large collection of AI models. The site provides many specialized models and ensembles for separating vocals, drums, bass, piano, guitar, wind, strings, percussion, keys and other instruments, plus multi-singer, choir (SATB), karaoke, crowd removal, and multichannel extraction. MVSEP also offers restoration and super-resolution algorithms, ASR and TTS models, audio-to-MIDI transcription, and experimental generative audio models. The service is aimed at users needing high-quality stem separation and related audio processing—from hobbyists using free separations to registered and premium users who get lossless exports, higher priority in queues, and additional formats.

MVSEP separates music into vocal and instrumental stems with AI and supports audio-to-text transcription. Mvsep is a AI Tool featured on Dang.ai. Learn more about Mvsep's AI tool.

Use Cases

Vocal/instrument separation and stem extraction

Extract vocals, instrumental, or detailed stems (vocals, drums, bass, piano, guitar, etc.) for remixing, karaoke, or analysis using specialized models and ensembles.

Karaoke and lead/back vocal isolation

Dedicated karaoke and vocal-extraction models (MVSep Karaoke, MDX-B Karaoke) for creating backing tracks or isolating lead vocals.

Audio restoration and upscaling

Use super-resolution and denoising models (AudioSR, Apollo Enhancers, DeNoise, Reverb Removal) to restore quality of compressed or degraded audio.

Transcription to MIDI and music analysis

Convert singing or piano performances to MIDI (SOME, Transkun, Basic Pitch) for notation, arrangement, or production workflows.

Cinematic audio separation (DnR) and SFX isolation

Cinematic models (BandIt, MVSep DnR v3) split speech, music and effects, and models for isolating specific FX (Braam, Risers).

Voice cloning and TTS generation

Generate synthetic speech or clone voices using VibeVoice and Qwen3-TTS variants for narration, dialogue generation, or voice design.

Noise/crowd removal for live recordings

MVSep Crowd removal model removes applause, clapping, whistles and other crowd noises from recordings.

Integrations

Whisper

Automatic speech recognition model available on the site for ASR and speech translation.

VibeVoice

Limitations

Some higher-quality encodings and bit depths (wav/flac 16/24/32-bit) are gated to registered or premium accounts.
Processing is queued and subject to GPU availability (site shows 'Unprocessed files in queue' and 'Currently processed with GPU').
Specific models (example: HeartMuLa) may struggle to follow tags and are computationally heavy, requiring significant VRAM.
