/* Experience created by Josep Antoni Bover for https://devildrey33.es.
* This Audio shader is a part of my Audio-PlayGround experience :

*
* #7 Floor and bars effect.
* - Play with Audio Strength, Line size, and radius to achieve different effects
* - This script creates an audio data texture with the getByteTimeFrequency values
* on the red channel and the getByteTimeByDomain on the green channel. (Its more easy than creating extra attributes, and looks better)
* - Then this texture is sent to the sunset shader and the sunset depth shader.
* - You can drag & drop any song of your computer to play it.
* - Song name : Alone
* Song artist : Color Out
