JUCE features and specs

  • Cross-Platform Capabilities
    JUCE allows developers to create applications that run on multiple platforms, including Windows, macOS, Linux, iOS, and Android, from a single codebase, which significantly simplifies the development process and reduces maintenance costs.
  • Comprehensive Audio Tools
    JUCE offers powerful tools and libraries for audio processing, making it particularly suited for developing music and audio applications. This includes support for MIDI, virtual instruments, digital signal processing, and more.
  • Extensive Documentation and Community Support
    JUCE provides extensive documentation and a robust community, making it easier for developers to learn and solve problems. New users can find tutorials, forums, and a wealth of examples to assist them in development.
  • Prototyping and GUI Designer
    JUCE includes a GUI editor, the Projucer, which allows developers to easily design interfaces and iterate on them quickly, streamlining the prototyping phase.
  • Open Source
    JUCE is open source under the GPL license, allowing developers to use and modify the source code freely under the terms of this license, fostering innovation and collaboration.

Possible disadvantages of JUCE

  • Licensing Costs
    While JUCE is free for open-source projects under the GPL, commercial use requires a paid license. This can be a drawback for startups or individual developers with limited budgets.
  • Complexity for Beginners
    For developers new to C++ or audio applications, JUCE might have a steep learning curve due to its comprehensive feature set and complexity.
  • Limited Visual Tools
    Though JUCE offers a GUI editor, it may not be as feature-rich or intuitive as some other dedicated UI design tools, which can limit the ease of creating complex user interfaces.
  • Performance Overheads
    High-level abstractions and cross-platform support can introduce performance overheads, which might be a concern for applications requiring highly optimized performance.
  • Updates and Maintenance
    Relying on an external framework like JUCE means dependency on their updates and maintenance schedule, which can sometimes introduce issues or delays for your project.

QuickJS features and specs

  • Lightweight
    QuickJS is designed to be lightweight with a small footprint, making it easy to embed in applications and suitable for resource-constrained environments.
  • Fast Startup Time
    QuickJS offers very fast startup times, which can be beneficial for applications that require quick script execution without a long initialization period.
  • Full ES2020 Support
    QuickJS supports the full ES2020 specification, providing modern JavaScript features and syntax, which is advantageous for developers who want to use the latest JavaScript features.
  • Embeddability
    Being easy to integrate into other applications or systems, QuickJS provides a simple C API, which facilitates embedding it in various software and platforms.
  • Single File Distribution
    QuickJS can be distributed as a single file, simplifying packaging and distribution without needing external dependencies.
  • Memory Efficiency
    Its memory efficient design allows QuickJS to run scripts in environments with limited memory resources, making it suitable for IoT devices and embedded systems.

Possible disadvantages of QuickJS

  • Limited Ecosystem
    QuickJS, being a relatively new and niche project, has a smaller ecosystem compared to more established JavaScript engines like V8, which means fewer libraries and community resources are available.
  • Performance
    While QuickJS is efficient, it may not deliver the same high-performance execution as more mature engines like V8, especially in applications requiring intensive computational processing.
  • Lack of Long-term Support
    QuickJS may not have the same level of long-term support and ongoing development as larger projects maintained by large companies or communities.
  • Single-threaded
    QuickJS runs in a single thread, which can be a limitation for applications that require multithreading support for parallel processing.
  • Limited Debugging Tools
    Compared to more popular JavaScript engines, QuickJS has fewer debugging tools and integrations, which might make development and troubleshooting more challenging.

  • Show HN: I made an additive synth with 10k oscillators
    It's called Sine Machine and it has 20 voices of 511 (don't ask) time-domain oscillators. By "time-domain," I mean actual oscillators. A lot of additive synths are essentially iFFT engines and offer "partials" whereas Sine Machine literally provides 10,000 free running oscillators (and 20k lfos to control pitch/vol of each). Having this kind of full control over these offers a lot of fun ability to arpeggiate and... - Source: Hacker News / 9 months ago
  • Python Audio Processing with Pedalboard
    Related discussion with comments by the author: https://news.ycombinator.com/item?id=28458930), a comprehensive C++ library for building audio applications. We at Spotify needed a Python library that could load VSTs and process audio extremely quickly for machine learning research, but all of the popular solutions we found either shelled out to command line tools like sox/ffmpeg, or had non-thread-safe bindings to... - Source: Hacker News / 12 months ago
  • C++ Is an Absolute Blast
    The amount of high performance, production grade, massively tested libraries written in C++ is unbeatable. I will be honest here, it's easier to improve C++ security by implementing a compiler that produces safer C++ (like Typescript to Javascript) than rewriting everything in any other language (Rust, Zig, Odin, whatever). I mean, could you estimate the cost ($ and time) it would take to rewrite the best audio... - Source: Hacker News / over 1 year ago

    That's a fun project - got any interest in a port to JUCE? https://juce.com/. - Source: Hacker News / almost 2 years ago
  • 3rd Edition of Programming: Principles and Practice Using C++ by Stroustrup
    Personally, I started by writing externals for Pure Data, then started to contribute to the care. Later I took the same path for SuperCollider. The more typical path, I guess, would be to start with simple audio plugins. Have a look at JUCE (https://juce.com/)! Realtime audio programming has some rather strict requirements that you don't have in most other software. Check out this classic article:... - Source: Hacker News / about 2 years ago

  • Vim 9.2 Released
    You don't need V8 for running JS for scripting, you have quickjs[1] or mquickjs[2] for example. You might have problems importing npm packages, but as we can see from lua plugins you don't even need support for package managers. Performance is not as good as luajit, but it is good enough [1]: https://bellard.org/quickjs/ [2]: https://github.com/bellard/mquickjs. - Source: Hacker News / 5 months ago

  • Building a JavaScript Runtime from Scratch using C
    For those who would like a true "from scratch" implementation of JavaScript, Fabrice Bellard's QuickJS [1] is clean, readable and approachable. It's a full implementation of modern JavaScript in a straightforward project, not nearly as complex or difficult as V8. [1] https://bellard.org/quickjs/. - Source: Hacker News / 9 months ago
  • The many, many, many JavaScript runtimes of the last decade
    I see a few mentions of QuickJS, but they all refer to the fork of Bellard's QuickJS https://bellard.org/quickjs/, which I think deserves a mention. It seems to be still active (last release 2025-04-26, GitHub mirror at https://github.com/bellard/quickjs shows some activity). - Source: Hacker News / 12 months ago
  • SQLite JavaScript: Extend your database with JavaScript
    This is a fantastic approach. BTW, it looks like the js engine is "QuickJS" [0]. (I'm not familiar with it myself.) I like it because sqlite by itself lacks a host language. (e.g., Oracle's plsql, Postgreses pgplsql, Sqlserver's t-sql, etc). That is: code that runs on compute that is local to your storage. That's a nice flexible design -- you can choose whatever language you want. But quite typically you... - Source: Hacker News / about 1 year ago
