I haven't blogged for ages (tsk tsk) been busy as usual and the months just seem to slide by.... Anyway - I have been interested in the relationship between sound and vision for a very long time now and have a backlog of demos and concepts that I shall try to dig out and publish. One of these recently surfaced and I thought I would share it.

Essentially, the audiovisualisation uses an audio track's overall volume to modify a complex geometric structure built from triangles. Nothing much new there although some pleasing shapes and reactions created by fine tweaking of the algorithms used. Perhaps the more interesting part is the use of colour which is directly based on the volume of individual frequency bands. As discussed elsewhere on this blog, it seems that the human brain is constantly trying to build relationships between sensory events in an attempt to make sense of environments and objects. When viewing this audiovisualisation it seems natural that the movement, form and colour tone are all directly related to the audio track.

It would be interesting to develop an alternative demo where there is no actual relationship and try to understand whether the brain tends to form one anyway! This was an old trick back in the days of live video mixing without sync when VJs would cut between a slow unsynced video track to a fast unsynced video track. When put to music it often seems that the video is actually entirely synced - although some of this can be put down to the human factor and knowing when to cut between tapes.

Anyway here it is. I will publish the code as soon as I have chance to tidy it up :-)



Incidentally, the track is one I've created myself as my alter ego 'Wah Wah Rabbit'. You can check out more like this here.
