This is not evident on our demo but we've engineered the ability for you to get waveform data and visualize that as you like. Right now we visualize equalizer data but it would be trivial to create a visualization for realtime waveforms etc..
Couldn't agree more. I work on Clyp (formerly Audiour) and I think one of our core differentiators is the time we spend on having a good looking soundwave. This is one of the main reasons we try to put it front and center on the player page.
