Hardware-accelerated demixing at the Edge
While Spleeter was groundbreaking for its time, many users now prefer the Demucs AI model for cleaner separation and more flexible stem options. Music Demixer harnesses Demucs in a web-based platform, offering privacy-friendly local processing and continuous updates.
Yes! You can separate stems at no cost using our free plan (up to 3 free jobs with our basic quality model). When you're ready for unlimited high-quality stems and additional features like MIDI transcription, you can upgrade to the PRO plan.
Music Demixer runs the AI processing locally in your browser. Your files never leave your device, keeping your audio private and secure.
Not at all. Music Demixer is fully web-based, so there's no installation or command-line interface required. Simply upload your audio, choose your settings, and let the AI handle the rest.
"The demixing was very good, and much better than I was getting with RX 10. Thank you for giving me this chance to try the PRO version."
"Your platform is the best music score generator I've found, and it keeps getting better with every update."
"I demixed the tracks with your app for my latest production project. The results were fantastic!"

Music Demixer (aka freemusicdemixer.com) is a web-based tool that uses the cutting-edge Demucs AI model to separate music into stems.
In this article, we compare Music Demixer to Spleeter, the AI model developed by Deezer that revolutionized stem separation in 2020.
Spleeter is an AI model, not a consumer website, so it's more fair to compare Spleeter vs. Demucs, which is the core AI technology used by Music Demixer.
However, Spleeter has led to many websites and tools that use it, so we will also do a comparison of Spleeter vs. Music Demixer to account for all of the web-based versions of Spleeter that exist. Out of all of the Spleeter alternatives, we propose that Music Demixer is a great choice for stem separation.
Spleeter, developed by Deezer, pioneered AI music separation as a free, open-source tool. While completely free and capable of 100x real-time processing on GPU, it requires Python installation, command-line knowledge, and 30-60 minutes of technical setup. Most users struggle with the installation process before even getting to the separation quality.
If you're looking for Spleeter but want something easier, you can start using Music Demixer right now - no installation needed. Just drag and drop your audio file above.
Music Demixer, powered by the cutting-edge Demucs AI model, offers superior stem separation with enhanced clarity, fidelity, and ease of use. Let's dive into why Music Demixer is the best choice for stem separation.
There are multiple Spleeter alternatives, and Demucs is one of the best, which is why Music Demixer uses it as our foundation. We have also developed custom ensemble models and strategies to further improve the quality of our stems. Keep reading to learn more about the differences between Spleeter and Demucs.
With Music Demixer, these problems don't exist - it just works in your browser.
Spleeter is powerful and free, but the user experience creates significant barriers:
Music Demixer harnesses the power of Demucs, a state-of-the-art AI model designed for high-quality audio separation. Key advantages include:
Music Demixer uses the latest trained AI models of Demucs that were improved and updated as recently as the 2023 Sound Demixing Challenge, and we are constantly experimenting with improving our algorithms and models.
Several popular tools and websites rely on Spleeter, inheriting its limitations:
If you install Spleeter on your computer, your audio files never leave your computer. However, installing it requires expertise in Python and AI software.
On web-based versions of Spleeter, your audio files are uploaded to a remote server for processing. This can be a privacy concern, especially if you are working with sensitive or unreleased audio.
Music Demixer uses a unique design: it's web-based, but delivers the AI model to your browser and performs the processing locally. Your audio files never leave your computer, ensuring they remain private and secure. Plus, you don't need any special setup — simply open Music Demixer and start demixing. We continuously test and refine it so you always have the latest and greatest version.
Many users search for "Spleeter online" or "Spleeter without Python" - that's exactly what Music Demixer provides. We've taken the complexity out of AI stem separation:
Spleeter's default models discard all frequency content above 11 kHz, while the newer 16kHz versions extend this to 16 kHz. However, the models weren't trained above 11 kHz, so higher frequencies often contain artifacts. This removes much of the "air" and "brilliance" from cymbals, vocals, and acoustic instruments. Music Demixer preserves full CD-quality 44.1 kHz (22 kHz frequency range), maintaining the complete sparkle and presence that makes music sound professional.
In simple terms: Even Spleeter's best configuration cuts off the highest frequencies that give music its sparkle - the shimmer of cymbals, the breathiness in vocals, the presence that makes music sound alive.
Here's a quick comparison of Music Demixer and Spleeter:
| Feature | Music Demixer | Spleeter |
|---|---|---|
| Audio Quality | Clear, artifact-minimized, high fidelity | More artifacts, less precision |
| Stems Supported | Vocals, Bass, Drums, Piano, Melody, Other (e.g. Violin) | Vocals, Drums, Bass, Accompaniment |
| Ease of Use | Web-based, no setup | Requires setup (locally) or reliant on 3rd-party sites |
| Platform Support | Any OS via modern web browser | Varies by Spleeter-based site; local install requires Python |
| Advanced Features | Ensemble models for higher quality | None |
| Extra Features | MIDI transcription (PRO plan) | None |
