Functional Description
Real-time plot of the second audio input
versus the first audio input.
For stereo inputs,
each channel is displayed in a separate plot.
NOTE: The name "Phase-Space Scope" is borrowed from dynamical system theory where
a plot of this type is commonly used for plotting the trajectory of one dynamic state (e.g. position
of an object) versus another (e.g. velocity of the object). Such plots can often reveal
useful information about the nature of the underlying dynamical system (e.g. the classic
"Butterfly pattern" of the famous chaotic Lorentz Attractor, see
[Gl] p. 114).
The plot properties are adjusted via the Parameter Window, as summarised
in the following table.
| Parameter | Purpose |
|---|
| "Number of points" slider | Sets the
number of samples in the "snapshot" buffer.
The "Reset" button restores
the default setting.
The plot is updated whenever the snapshot buffer is re-filled. The time elapsed between
successive
updates is displayed as the "Refresh period".
|
| "Plot scale" slider | Adjusts
the scale of the plot (the plot is symmetric so the X- and Y-scales are adjusted together).
The "Reset" button restores
the default setting.
|
| "Freeze/Unfreeze" button |
Freeze-frame toggle control. When the plot has been frozen, it is not updated again until it has
been unfrozen (even after the "stop" button has been pressed).

Signal Implementations
| Audio signals | Control signals | Description |
|---|
| Single input mono | n/a | Single plot displays second mono signal versus first mono signal. |
| Single input stereo | n/a | The "Left channel plot" displays the left channel
of the second stereo input versus the left channel of the first stereo input.
The "Right channel plot" displays the right channel
of the second stereo input versus the right channel of the first stereo input. |
