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.
