Audio visualizer

[Meekdai]

Feature Proposal

I found that in the examples/player, the waveform(siriwave.js) did not follow the music. Is there a way to achieve this which shown in the link below

https://foobar404.dev/wave.js/

Possible Implementation

1. Does howler.js have an API that can obtain the amplitude and frequency of the current music? So that I can provide it to siriwave.js.

2. Using wave.js requires an audioElement, which I cannot get in howler.js.

I have read the following links #771 , but there is no good solution

I also need to provide new apis to help me visualize the audio.

same problem.

Regarding Workaround 2 (wave.js), you can get the audio element with:

var node = audio._sounds[0]._node
//node is an HTMLAudioElement
