I asked this on the Nyquist mailing list about a week ago, but it
appears that no-one knows, so I'm hoping that an Audacity developer may
be able to shed some light.
I notice that the word "rate" can be used as a parameter with slider
for example, the following plug-in will display the current sample rate:
;action "show ..."
;info "Show Sample Rate"
;control n "Sample Rate" int "Hz" rate 0 1000000
Is this documented anywhere?
Are there any other "keywords" that can be used in this way?
Perhaps there are some comments in the source code about this, but I
don't know what part of the source code is responsible for this, so I
don't know where to look.
(I will be happy to write something up on the Audacity wiki if anyone is
able to provide definitive information about it).
