sorry, i have a few questions today, i know it's bad from to ask them
all in one thread, but i don't want to start too many threads.
question 1)
how do you multiply a signal by a power of n ? can you do it with expr~?
do you mean take a signal to the nth power?
to square a signal (ie signal^2) do this:
[osc~]
|\
| \
[*~]
|
[dac~]
to cube the signal, take the output of the [*~] above and pass it through
another [*~] which takes the original signal [osc~] as its other input.
question 2)
is there a list of the functions that i can use with expr~ (and expr)
? i have seen many of these functions in other peoples patches, but
can't find them in pd's documentation.
i'd be interested in this myself..
question 3)
i want to insert a percentage of random noise into a signal. ie, for
every oscillation of an [osc~] i want 25% of the samples to be
converted into noise. the level and position of the noise should be
random, but 25% of the samples in each oscillation must be be
converted into noise.
any idea how to do that?
i'm not sure i understand what you mean by 25%. do you mean you want to mix
an osc~ signal and a noise signal with the noise being 25% of the amplitude
of the osc~ signal? or do you want to have an osc~ signal interspersed with
noise such that the noise occurs 25% of the time and the osc~ the other 75%?
