I would like to be able to link the soundwave of a recorded sound to a wall :
(sound fit to the lenght of the wall, like an image can fit to a size of a piece of paper)
One part of the wall is activated which activate just one part of the sound,
If your soundwave is long enough you can play a fragment of this soundwave in loop and set the start position of the loop according to the activated part of the wall. You can easily achieve the playback part with the groove~ object.
