2 summary:: A nice wrapper for FreqScope
4 related:: Classes/FreqScope
7 FreqScope shows the frequency spectrum of the specified audio bus. The scope will remain active after a command-period. To turn it off you must either click off the 'Power' button or close the window.
11 ## Power || Turns the scope on and off. This is useful for freezing the signal on the display or for saving CPU.
12 ## BusIn || The audio bus to be analyzed.
13 ## FrqScl || Determines the mapping of frequencies on the x-axis. Can be linear (lin) or logarithmic (log). Logarithmic is equal spacing per musical octave.
14 ## dbCut || Determines the lowest decibel shown on the y-axis.
25 The number of the audio link::Classes/Bus:: to be monitored.
27 An instance of link::Classes/Color::. The drawing color of the scope.
29 An instance of link::Classes/Color::. The background color of the scope.

53 subsection:: Subclassing and Internal Methods
55 The following methods are usually not used directly or are called by a primitive. Programmers can still call or override these as needed.
58 Returns a link::Classes/Boolean::, whether the scope is open.

67 Returns the window in which the FreqScope view is placed.
