A little experiment with the first of the Toulon Library recordings where it was played on the Windows Media Player with the 'Rhythmic Colours' visualization.
I've then recorded that playback as a video before attaching the original (better quality) recording as audio. Finally, the imagery has been filtered/pixelated so that it makes a more grid-like approximation of the sound visualization as coloured squares that actually grow in size as the video progresses. At times, the seemingly random colour combinations prove interesting.
It's a relatively quick exercise (even with the Youtube upload) but I'm wondering about its application as a more fully realised and perhaps sharper visual project that takes on new meaning without the audio track. (Obviously, an idea of how this might work is achieved by simply muting the volume.)
