Shoe Tapping Audio/Video Syncing – Max Documentation


Tapping your shoes on the floor has never been so stimulating.  This big, interactive idea encompasses the manipulation of visual display through physical exertion of the feet.


Hit the keys on the in-program MIDI input and you will activate the program’s catalyst. This MIDI input acts as a substitute for the tap of the shoe. It is simply an alternative manual input, in place of shoe tapping, for the patch. Sometimes, creators must compromise certain aspects of their design and a MIDI is a fit compromise. Every note triggers the rest of the patch to activate.

Connected to four separate oscillators that are to be toggled on and off, MIDI notes run through these gated circuits and are manipulated by the oscillation they’re filtered by. Each have a distinct effect on the final audio result.


In having further control, manipulating vertices on the line graph also affects the output to a greater extent, providing different delay and attack values like a mixer would. Delays between each of the value shifts emulate the tapping of a shoe. The graph allows for complete control over every and any value, making the room for variance that much more complex.


In order to hear anything, we have to enable sound to come through by raising our gain. Additionally, we need to toggle on the audio output. This will also allow us to affect our visual display.


And finally, our end result takes the form of visuals affected by waveform. With every note played, or foot tapped, displays and sounds are distorted. Now we have a full system of input affecting output.

Ultimately, a system like this one could have several implications for society. We could see this system being used for the blind as an additional receptor for navigation. As there are plenty of probing canes used already for the blind, audio may also play a small role in the process. Attaching a receptor to the end of the cane can allow for sound to emit from the device, further adding to the identification of barriers and pathways.

For runners, this could allow for a pacemaking machine. As an avid runner myself, I always find myself inconsistent with my mile pacing. If this shoe-laced device was ever patched to headphones in some way, runners could have an auditory representation of their pacing, distributing their velocity among laps.

Whether for the disabled on one side or athletes on the other, this pressure-to-auditory/visual system could come in handy. We should take advantage of these systems in the future and advance further in the realm of patching.
