MVSEP

MVSEP is an audio-separation service for musicians, editors and developers working across web, mobile and API workflows. It is particularly well suited to users who need many specialist stem and speech models rather than only a vocal remover. The free tiers are unusually usable for routine work, while longer tracks, higher-quality exports and automation make Premium credits a more deliberate purchase.

Overview

MVSEP separates recordings into voice and music components, then extends that core job with vocal removal, karaoke creation, stem splitting, speech isolation, noise removal, reverb removal and audio upscaling. Its stem coverage includes vocals, instrumental, bass, drums, piano, guitar, lead and backing vocals, choir, synth, percussion, strings, wind, brass, woodwind, speech, music and effects. That range suits production and cleanup projects that outgrow a simple two-track split.

More than 100 AI models cover vocals, instruments, speech processing, transcription, MIDI extraction and voice generation. This breadth is the service's main differentiator, but selecting among models is part of the workflow. Premium also unlocks Ensemble models, and credit consumption varies by model type.

Key features

• Broad processing set: Karaoke, stem extraction, speech isolation, denoising, dereverberation and upscaling make MVSEP useful for both music production and spoken-audio repair.
• Flexible output: MP3, WAV, FLAC and M4A are supported. Free accounts receive 16-bit WAV and FLAC; Premium raises these to WAV 32-bit float and FLAC 24-bit, which matters for subsequent editing and mastering.
• Credit accounting: Credits are prepaid. Standard models charge the full audio duration, Ensemble models multiply the minutes, and every job costs at least one credit. Frequent users therefore need to estimate model-dependent usage rather than budget by track count alone.
• Developer access: The API can create separations, retrieve results, inspect algorithms and queues, manage users and access separation history. Regional endpoints are provided in Germany, Germany 2 and Singapore; the Hong Kong endpoint is deprecated.
• Batch and desktop options: Premium includes batch processing. MVSEP also supplies a Windows EXE for its API examples that needs neither Python nor an installation, reducing friction for Windows developers.
• Data 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. Upload pages use Cloudflare Turnstile, with no analytics cookies; traffic statistics come from server logs.

Pricing

Unregistered — free: This tier allows files up to 10 minutes and 100 MB, 50 separations daily, one concurrent job and access to 100+ AI models. MP3 is the export, queue priority is low and a captcha is required. It is suitable for occasional, short jobs, but the single job and MP3-only output constrain serious editing.

Registered — free: The same 10-minute, 100 MB and 50-daily-separation caps remain, as does one concurrent job and 100+ model access. Registration removes the captcha, raises queue priority to medium, adds limited API access, and permits MP3, WAV, FLAC and M4A, with WAV and FLAC at 16-bit. This is the practical free choice for regular users who need lossless-format exports or basic automation.

Premium — custom pricing: Premium is prepaid, credit-based and non-recurring unless otherwise stated for direct website payments. It accepts tracks up to 100 minutes and 1000 MB, removes the daily separation cap, permits unlimited concurrent jobs, adds Ensemble models, high queue priority, batch processing and full API access. It also provides the higher-resolution WAV and FLAC formats. The trade-off is that the price is not published and credit use changes with the chosen model, so it is best for users with predictable, sustained workloads rather than someone seeking a simple monthly allowance.

Platforms

MVSEP runs on web, Android, iOS and Windows, and exposes an API. The iOS app and updated Android app are live. Its maximum upload is 1000 MB and maximum track length is 100 minutes, although free tiers impose the shorter 10-minute and 100 MB limits.

Who it's for

Choose MVSEP for detailed music stem work, speech-focused cleanup, model experimentation or an integration that needs separation history and queue information. Registered users get a capable no-cost starting point, while Premium fits studios, developers and batch-oriented workflows. It is less suitable when you want a clearly priced subscription, a very simple fixed model, or unrestricted long-track processing without tracking prepaid credits.

Pros and cons

• Pro: More than 100 models and extensive stem types cover specialized music and speech jobs.
• Pro: The registered free tier offers 50 daily separations, four formats and limited API access without a captcha.
• Pro: Premium combines 100-minute, 1000 MB uploads with unlimited daily and concurrent processing, batch jobs and full API access.
• Con: Free users are limited to 10-minute, 100 MB files and one concurrent job.
• Con: Premium pricing is custom, and Ensemble or model-specific credit multipliers make costs harder to predict.
• Con: Unregistered processing has low queue priority and requires a captcha; Premium is needed for the highest-quality WAV and FLAC exports.

Alternatives

Browse AI Stem Splitters or Stem Separation Software for a wider category comparison. Pick LALAL.AI instead if you need Linux or macOS support and are comfortable with a free Starter tier that limits relaxed-queue use to 10 minutes and 200 MB, with previews but no full downloads. Pymss is the better fit for an open-source, locally running free tool. Choose Moises for a simpler mobile and desktop service whose free plan allows five uploads per month, five-minute files and limited stem options. Fadr suits remixers wanting MIDI detection and Remix Maker on its free Basic plan. BandLab Splitter is preferable for unlimited uploads under 15 minutes and four stems, while Sonura targets loop and one-shot creation. Suno is an alternative for generative music workflows, and StemRoller for a free, open-source desktop option on macOS and Windows.

Verdict

MVSEP is a strong choice for musicians, audio editors and developers who value model variety, broad stem coverage and an unusually generous registered free tier. Its API, batch tools and long-track Premium limits reward structured, recurring workflows. Look elsewhere if you need transparent Premium pricing or a simpler, fixed-cost experience, because prepaid credits and model-dependent multipliers require active cost management.
