MVSEP

MVSEP is an audio-separation and cleanup service for musicians, editors, and developers working with music or speech. It is particularly suitable when you need many specialized stems, model choices, or an API rather than only a vocal remover. The free tiers are unusually usable for short files, while longer tracks, higher-quality exports, and heavier automation push you toward Premium credits.

Overview

MVSEP separates voice and music, then extends that core job with vocal removal, karaoke creation, stem splitting, speech isolation, noise and reverb removal, and audio upscaling. Its stem catalog covers vocals, instrumental, bass, drums, piano, guitar, lead and backing vocals, choir, synth, percussion, strings, wind, brass, woodwind, speech, music, effects, and other parts. That range fits remixing and production projects as well as dialogue cleanup, although choosing among many models may require more judgment than a single-purpose tool.

More than 100 AI models span vocals, instruments, speech processing, transcription, MIDI extraction, and voice generation. Premium adds Ensemble models. Standard models consume credits according to audio minutes, while Ensemble models multiply the minutes used; every job costs at least one credit, so frequent processing needs careful credit management.

Key features

• Broad processing set: Separation, karaoke, speech isolation, noise and reverb reduction, and upscaling make MVSEP useful beyond extracting a vocal track.
• Flexible exports: MP3, WAV, FLAC, and M4A cover common delivery needs. Free accounts receive 16-bit WAV and FLAC; Premium increases those to WAV 32-bit float and FLAC 24-bit, a meaningful distinction for further editing.
• Batch and automation: Premium includes batch processing and unlimited concurrent jobs. The API can create separations, return results, expose algorithm and queue information, manage users, and access separation history.
• Privacy handling: Uploaded files are deleted after one day, working copies after three days, and generated outputs and processing records after three days. MVSEP says uploads and outputs are not used to train, fine-tune, or evaluate machine-learning models.
• Operational safeguards: Upload pages use Cloudflare Turnstile. The site sets no analytics cookies and derives traffic statistics from its own server logs. Email support targets replies within 24–48 hours on business days.

Pricing

Direct website payments are one-time and non-recurring unless stated otherwise. Premium's missing published price makes budgeting harder, and credit use varies by model; it is not a simple unlimited subscription. Free plans are generous for short work but their 10-minute ceiling, 100 MB cap, daily quota, and single-job concurrency rule out sustained long-form production.

Platforms

MVSEP runs on web, Android, iOS, and Windows, and offers an API. Its Windows EXE examples run without Python or installation. Regional API endpoints are provided in Germany, Germany 2, and Singapore; the Hong Kong endpoint is deprecated. The combination suits teams splitting work between a browser, phone, desktop scripts, and hosted workflows.

Who it's for

Choose MVSEP for remixers, karaoke makers, producers, and editors who need more than vocals and instrumental, especially when speech cleanup or unusual instruments matter. Developers benefit from queue and algorithm information, user management, history access, and regional endpoints. It is less suitable for anyone needing a clearly priced unlimited plan, files longer than 100 minutes, or a simple one-click workflow with no model decisions.

Pros and cons

Pros

• More than 100 models and an unusually wide stem and processing range.
• Registered free use includes 50 daily separations, four output formats, and limited API access.
• Premium supports 100-minute, 1,000 MB files, batch work, parallel jobs, and high queue priority.
• Short retention windows and a stated no-training policy reduce exposure for uploaded audio.

Cons

• Free uploads stop at 10 minutes and 100 MB, with only one concurrent job.
• Premium pricing is custom, and credit consumption changes by model, complicating cost forecasts.
• Unregistered use requires captcha and has the lowest queue priority; even registered API access is limited.

Alternatives

LALAL.AI is a better fit if you want broad platform coverage including Linux and macOS, but its Starter tier limits files to 10 minutes and 200 MB, offers previews, and withholds full downloads.

Moises suits a simpler consumer workflow, while its free plan allows five uploads per month, five-minute files, and limited stem options.

Pymss is the alternative for users who specifically want free, open-source software that runs locally.

Fadr is worth considering for MIDI detection and its Remix Maker alongside vocal, melody, drum, and bass separation.

BandLab Splitter fits users wanting four stems and unlimited uploads for files under 15 minutes, with a paid Pro tier.

Sonura is aimed at loop, one-shot, effects, and full-track creation rather than MVSEP's broad separation toolkit.

StemRoller is a free, open-source macOS and Windows option for vocals, drums, bass, other instrumental stems, and an instrumental track.

Suno is the better choice when generative music creation and daily credits matter more than detailed stem extraction.

Verdict

MVSEP is a strong recommendation for musicians, editors, and developers who value model variety, specialized stems, and API access, with a free quota that supports serious short-file experimentation. Look elsewhere if predictable subscription pricing, very simple operation, or longer-than-100-minute files are your priority.
