What is the Web Audio API and how can I use it?

The Web Audio API is a powerful tool for processing and synthesizing audio in web applications. It allows you to create complex audio applications, including games and music visualizations.

Can you give me an example of how to create a simple sound using it?

Sure! You can create a simple sound by using the AudioContext and OscillatorNode. Here's a basic example:

const audioContext = new (window.AudioContext || window.webkitAudioContext)();
const oscillator = audioContext.createOscillator();
oscillator.type = 'sine';
oscillator.frequency.setValueAtTime(440, audioContext.currentTime);
oscillator.connect(audioContext.destination);
oscillator.start();
oscillator.stop(audioContext.currentTime + 1);

What types of audio processing can I do with it?

You can perform various audio processing tasks such as filtering, spatialization, and effects like reverb and delay. The API provides nodes for each of these functionalities.

Are there any good resources to learn more about the Web Audio API?

Yes! The Mozilla Developer Network (MDN) has excellent documentation, and there are many tutorials available online that cover different aspects of the API.
