[chuck-users] something new to think about.

[David Elkin-Ginnetti]

How about defining the threshold initially as a greater frequency and then only allowing it to deviate a specified number from the original frequency? That way it won't always increase as quickly. So, I'm thinking, in the beginning, instead of 0 => float threshold, replacing that with

200 => float threshold;

and then instead of both instances of Std.rand2f(1, 15000):

Std.rand2f( threshold-300, threshold+300 );

That way the frequency couldn't go up more than 300 hz (or some other number) at a time. Does that sound more like you were thinking? Warning: code also hasn't been tested.

peace,
David Elkin-Ginnetti
