create an output sound to an input video for a glsl shader
-
Hello
I have made a lot of real time parameters to a glsl shader using sound level but i don't find the way to create a link between sound and video input shader.
Skulpture have made this link on you tube
but i don't understand which kind of channel input he had use
thanks a lot

@Skulpture Any thoughts?

I am pretty sure, what he would have done is used a Sound Frequency Bands or Sound Frequency Watcher actor/s. In live capture settings (input/live capture settings) in Isadora you need to select a Sound Input device, ensure 'Sound Frequency Analysis' is checked, and Start Live Capture. That will provide the audio source to the Sound Frequency Bands or Sound Frequency Watcher actor/s in your scene. These actors allow you to convert audio frequency values into numeric outputs in Isadora. These numeric outputs can then be fed to your GLSL shader actor to control inputs, making the GLSL audio reactive.

Something like that probably.... I think I managed to publish an input in the code. This was 5 years ago... can't fully remember.
