Hi list, i'm trying to study fft in Pd and still don't
understand the numbers produced by the analysis.
I'm on Pd "vanilla" 0-40.2 in debian. I just patch
this:
[float]
| \
| \
[osc~] \
| \
| [bang]
| /
[rfft~] / |
\ \ |
\ / \ |
\ / [print~ imaginary]
[print~ real]
and then type "0" and "1" in float box and this
analysis came to terminal:
real:
