I suggest you do some experiments before you give a talk. At 4 Hz you
won't be able to hear anything, you won't even be able to reproduce a
4 Hz sound with common speakers.
You took me quite literally, [I did put the vibrate into quotes :-) ]
Let me spell out the experiment in more detail:
Say I have a rhythm in 4/4 time -- 4 even quarter notes, bar repeating every second played by say a click. [What kind of click I am not very sure; sharp with few harmonics would be best I expect]
Now if there were some (realtime) way of sliding the tempo from 1 sec to millisec I expect the separate clicks would vanish into a hum at some stage.
This (and other such experiments) is what I want to demo.
Ive started looking at chuck.
How does it compare with puredata?

puredata springs to mind, it's easy to use and has everything you need.
