Features and specs

What each product offers, as listed by its team.

React-Ionic 5 features
StemX App 12 features
  • Cross-Platform Development
    React-Ionic allows developers to build applications that run on both iOS and Android platforms using a single codebase, effectively saving time and resources.
  • React Ecosystem
    Integration with the React ecosystem provides access to numerous libraries and tools, allowing developers to use familiar technologies and streamline the development process.
  • Ionic Components
    Leverages Ionic's UI components that are designed to look and feel native on both iOS and Android, providing a consistent and polished user experience across platforms.
  • Live Reloading
    Features like live reloading and hot module replacement can speed up the development process by allowing developers to see changes in real-time.
  • Community Support
    Being part of the larger React and Ionic communities, developers can tap into extensive community support and resources to help solve issues and improve their applications.

Possible disadvantages

  • Performance Overhead
    Applications built with React-Ionic may experience performance overhead compared to fully native apps, which can be a concern for performance-intensive applications.
  • Learning Curve
    Developers new to the ecosystem might face a learning curve due to the combination of React and Ionic concepts and components.
  • Platform-Specific Customization
    While React-Ionic provides cross-platform functionality, achieving platform-specific look and feel or leveraging native features can require additional customization and work.
  • Ecosystem Dependence
    Reliance on both the Ionic framework and React means developers must stay current with updates and changes in both ecosystems, which can cause maintenance challenges.
  • Bundle Size
    The inclusion of both React and Ionic libraries can lead to larger application bundle sizes, which might impact load times and performance on lower-end devices.

Questions & Answers

As answered by people managing React-Ionic 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.
