class:: PV_MagFreeze
|
|
summary:: Freeze magnitudes.
|
|
categories:: UGens>FFT
|
|
|
|
Description::
|
|
|
|
Freezes magnitudes at current levels when code::freeze:: > 0.
|
|
|
|
|
|
classmethods::
|
|
|
|
method::new
|
|
|
|
argument::buffer
|
|
|
|
FFT buffer.
|
|
|
|
|
|
argument::freeze
|
|
|
|
If > 0, then magnitudes are frozen at current levels.
|
|
|
|
|
|
Examples::
|
|
|
|
code::
|
|
|
|
s.boot;
|
|
