The Sonic De-Scrambler was an audio spectrogram visualisation tool I developed for the TV show Easter Eggs Live, which was broadcast on Channel 4 over easter weekend. Sound recordist Chris Watson was using contact mics to listen to the sounds coming from inside the eggs and the producers of the show wanted to provide a visual display of the sound. The visualisation software was developed in Processing and was based on code written by John Locke and Kyle Janzen. The additional features which I added were:
- Frequency labels
- Ability to view amplitude in dB or linear scales
- Switchable viewing angle
- Fade effect
- Audio signal display
- Discards old data (original version accumulated data which meant the frame rate dropped over time)
- Increased resolution
- Colour fades from red (low freq.) to blue (high freq.)
The code can be downloaded here.
