Features and specs

What each product offers, as listed by its team.

Moises 5 features
StemX App 12 features
  • Audio Separation
    Moises offers advanced AI-driven audio separation, allowing users to isolate vocals, drums, bass, and other instruments from any song, which is particularly useful for musicians and producers.
  • User-Friendly Interface
    The platform is designed with a user-friendly interface that makes it easy for even non-technical users to navigate and utilize its features effectively.
  • Practice Tools
    Moises includes tools like tempo change, pitch shift, and metronome, which aid musicians in practicing and mastering songs at their own pace.

    Moises is available on various platforms, including web, iOS, and Android, offering flexibility in how and where users can access the service.

Possible disadvantages

  • Subscription Cost
    While Moises offers a free version, many advanced features are locked behind a subscription model, which might be a barrier for some users.
  • Internet Dependency
    Since Moises relies on cloud-based processing, a stable internet connection is necessary. This might be problematic for users with limited or unstable internet access.
  • Processing Time
    Audio processing can take time, particularly for longer or more complex tracks, which may cause delays in workflow.
  • Privacy Concerns
    Uploading audio files to the cloud raises potential privacy concerns, especially for users working on sensitive or copyrighted material.

    The app provides limited functionality in offline mode, which may hinder users who need to work in environments without internet access.

Questions & Answers

As answered by people managing Moises and StemX App.

What makes your product unique?

StemX App's answer:

Every model StemX runs is licensed for commercial use, and we publish how accurate each one is. The vocal remover uses UVR's MDX-Net models; our own benchmark measured 11.43 dB SI-SDR on vocals (7-second excerpts of 12 MUSDB18 tracks, a small benchmark, and we say so). The BPM finder is within 4% of the true tempo on 81.9% of 998 test tracks, and the key finder names a key only when it's confident: it answers on about 44% of songs and is right about 80% of the time when it does. If a result isn't reliable, StemX says so rather than guessing.

Why should a person choose your product over its competitors?

StemX App's answer:

You can try it before you commit: upload a song and hear a free 60-second preview of the vocals and instrumental without creating an account. The BPM and key finders are free, analyse the whole song rather than a clip, and show half and double time. Because the models are licensed for commercial use, developers and businesses can build on the API without licensing questions. Uploads are deleted automatically, after 1 hour for anonymous previews and 3–30 days for full splits depending on plan.

How would you describe the primary audience of your product?

StemX App's answer:

Singers and karaoke fans who want an instrumental of a song, producers and DJs who need acapellas, instrumentals or a track's tempo and key for remixes and sets, musicians making practice and backing tracks, and developers who want to add vocal separation or key/BPM detection to their own apps through an API.

What's the story behind your product?

StemX App's answer:

We set out to build a stem separator we could stand behind: one that only uses models whose licences allow commercial use, and that states its accuracy openly instead of making marketing claims. That's why StemX offers two stems (vocals and instrumental), not four. We couldn't find commercially licensed weights for the models that split further, so we ship what we can legally offer and publish how well it performs.

Which are the primary technologies used for building your product?

StemX App's answer:

Python and FastAPI for the API, PyTorch and ONNX Runtime for inference on NVIDIA GPUs, UVR MDX-Net for separation, Beat This! (CPJKU) for tempo and S-KEY (Deezer) for key detection, Next.js for the website, PostgreSQL, and Google Cloud (Cloud Run and GPU VMs). Payments are handled by Paddle.
