Intelligent Signal Display

I while ago, I came up with an idea for a better way to show audio signals as waveforms on a computer screen.

At the time, I was doing some dialogue editing on a television mini-series, and became increasingly frustrated at the amount of time I had to spend zooming in and zooming out on the waveform. I began experimenting, and Intelligent Signal Display (ISD) was born.

Intelligent Signal Display as an improved waveform display method where the waveform images are shaded to provide more detail. Here's an example image:

When the audio signal 'moves' faster (which happens with higher frequencies) the centre region of the waveform is shaded darker.

When the audio signal moves slower (ie: low frequencies) the centre region is shaded lighter. This actually corresponds to exactly what the waveform looks like when you zoom in on it so far that you can see the individual cycles.
