A function featured in electronic music visualizers and media player software that creates animated graphics based on a piece of music is known as music visualization. The picture is frequently created and presented in real-time, in a fashion that is coordinated with the music as it is played.
The Web Audio API is used to handle audio operations inside an audio context and was created with modular routing in mind. Audio nodes are joined together to form an audio routing graph and are used to conduct basic audio operations. Even within the same context, many sources with various channel configurations are permitted. This modular architecture allows you to easily construct sophisticated audio functions with dynamic effects.
Note: You are expected to know the basics of javascript and three.js before getting started with this project.
The Web Audio API involves handling audio operations inside an audio context and has been designed to allow modular routing. Basic audio operations are performed with audio nodes, which are linked together to form an audio routing graph. Several sources — with different types of channel layouts — are supported even within a single context. This modular design provides the flexibility to create complex audio functions with dynamic effects.
The audio pipeline starts by creating an audio context. It should have at least a single audio source — which can be thought of as an entry point for external files, mic input, oscillators, etc. Once we have a source in place, the signal is processed and moved ahead in the pipeline using audio nodes. After processing, the signal(s) are routed to the audio destination, which can only be a single one in the whole context.
The simplest illustration has a single source and a destination, without any effects or processing, inside the context. Why would anyone use this? Maybe they just want to play the sound without any changes.
On the left is an example of a much more complex setup, which can also be made using this API.
