As the delays shorten, the fundamental will rise into more realistic pitch ranges. Having a working tool will allow us to probe network conditions under which the delays become shorter. Tactile audio feedback is the idea of returning the audio signal to a haptic controller device in the hands of the user. Other timbres based on waveguides including percussion, woodwind instruments, simulations of instrument bodies, etc. can be added to the synthesis choices for the application. Singing voice is also a possibility in this case, the glottis becomes the delay-based element and the particular vocalization could be mapped to other QoS parameters.
Reverberation based on interconnections between multiple machines is an intriguing possibility.
Imagine a mesh of connections which is an assortment of delay paths between a number of sites. Change the absorption characteristics of such a reverberator and the circuit becomes a 2-D drum surface which is topologically like the reverberation case, but now a connection mesh which can also be impulsively excited to sound like a drum, gong or cymbal stroke.
