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?
I am preparing to give a talk on the wider
ramifications of music.
One of the things I wish to demonstrate is that things that look
different
are merely analogs but at different scales.
eg if something vibrates at 400Hz we hear a sound of A-flat. If it
'vibrates' at 4 Hz we hear a beat.
In the same analogy a 2 vs 3 poly-rhythm (should?) change to a do-so
chord.
And so on.
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.
Is there some
kind of software where I can make a 4 Hz beat and pull a
slider or a freq text box entry until it sound like a A-flat note?
puredata springs to mind, it's easy to use and has everything you need.
Regards,
Philipp
