Granular synthesis is a form of musical sound generation
where what is heard is constructed out of very brief sound fragments.
These fragments are called
and have a duration of 100 to 1 ms.
A question that is relevant to the real-time control of granular synthesis is:
“At what level of detail could the state of ongoing sound generation be displayed via touch?”
A pilot experiment indicates that this is possible
at the level of individual grains
It seems that force pulses applied to the human fingerpad
may display grain state,
via their presence, duration, amplitude, and vibrational content.
Moreover, this can happen
at the same timescale as that of sonic grains
