15 Web Audio API Examples
The Web Audio API opens the door to creating complex audio graphs, where sound sources (oscillators, audio files) connect to processing nodes (filters, reverb) and finally to the speaker output. This collection demonstrates how to use the AudioContext and its nodes for low-level DSP (Digital Signal Processing), allowing you to manipulate frequency, amplitude, and spatial position of sound. Explore how to build custom synthesizers and audio effects right in the browser.
