Feature request: Audio input uniform variable about glslviewer HOT 6 CLOSED

True! Thanks again. For those interested please read https://github.com/patriciogonzalezvivo/glslViewer/wiki/Compiling-with-Audio-and-Video-support

from glslviewer.

shadertoy.com has more audio input data in its uniforms than just 4 numbers. See:
https://www.shadertoy.com/view/Xds3Rr

shadertoy also lets you write sound shaders that generate audio. Click on the "Sound" tab to see the sound shader with its mainSound entry point:

I think it would be good to replicate the shadertoy interface. Then we could run the shaders I linked to in glslViewer. We'd need to select a good cross-platform audio library to support this, as you mention.

What about the possibility to link OSC messages/events to uniforms?
Trying to find ways to get more "life" data to GLSLViewer for VJing... in a flexible way.

OSC would be a killer feature! I imagine the perfect setup with shaders, rpi and touchOSC on a phone.

For each frame, I'd like to sample the live audio stream for dominant frequencies and amplitude data, so my shader can react to the music.
The audio data doesn't have to be precise so could perhaps be input by a cheap microphone.
Then turn it into a varying vec4 or mat4for example...? Would this be feasible?

I guess we can close this issue, what do you think @patriciogonzalezvivo ?
