A Web Audio metronome demonstrating rock-solid audio timing using setTimeout and Web Audio scheduler collaboration.
Metronome is a Web Audio-based metronome application that demonstrates how to achieve precise audio timing in web browsers. It solves the problem of browser timer throttling that can disrupt audio applications when tabs are not visible by implementing a collaboration between setTimeout and Web Audio scheduler.
Web developers and audio engineers building web-based audio applications that require precise timing, such as sequencers, drum machines, or interactive music tools.
Developers choose this project because it provides a working example of how to implement rock-solid audio timing despite browser limitations, with practical solutions for timer throttling issues that affect many web audio applications.

Uses the Web Audio API's scheduler to ensure accurate metronome ticks, addressing timing issues common in web audio apps as highlighted in the README.
Implements a web worker to handle setTimeout throttling when tabs are inactive, a practical solution described in the README to maintain consistent timing.
Linked to detailed articles on web.dev and developer.chrome.com, providing context and learning opportunities for audio scheduling techniques.
Offers a live app at https://cwilso.github.io/metronome/ for immediate testing and understanding of the implementation, making it accessible for hands-on learning.
The README admits the worker thread solution might no longer be necessary due to browser changes, but it hasn't been tested or removed, risking unnecessary complexity.
As an educational example, it lacks advanced features like customizable UI, error handling, or support for complex audio sequences beyond basic metronome functionality.
Relies on Web Audio API and specific browser behaviors, which may not be consistent across all environments or could break with future updates, as noted in the README.
