By happenchance I noticed that Windows Media Player was displaying a real-time oscilloscope display (and a static URL) whilst playing back a particular .MP3 file. (An amazing Safri Duo almost-tribal drumbeat, but it’s not relevant.)
I’ve seen static images embedded before (using MP3-tag programs) but… real-time oscilliscope display?
How is this done?
(Mods – Feel free to move if I’ve posted in wrong area, ‘cos this seems to be more about the MP3 format than the display app)
