Senseless Behaviour

I managed to get an 18000+ line text file from the audio clip, which I’ve been playing around with in various ways and have now ended up with a huge hex dump that has a PNG signature, IHDR chunk and IEND chunk… but I can’t figure out how to view it as an image, and can’t find any useful looking strings in it.

Am I on the right track with this or have I gone way off course or even been trolled by the creator? Could use a nudge either way…

What tool did you use ?
