7.2.6 Trace screen tone audible Graph playback
Tone audible Graph playback (TAGP) refers to the announcement of the graphs
in the form of audible tones. TAGP is applicable only when Tone mode is
selected and the active screen on the TI-84 Plus is in Trace mode. Tone mode is
when each plotted point of an equation is made audible with a tone
corresponding to its Y-coordinate. As you navigate (trace) the plotted graph of
the equation, tones are issued for each point. Alternately, the entire graph for an
equation can be heard by pressing both Orion Playback Pref. key and the Shift
key at the same time.
Details are as follows:
•
The frequency of the tone generated corresponds to the Y-coordinate
values of the plotted points of an equation.
•
The balance between the left and right speaker represents the X-
coordinate value. (The left-most point plays only in the left speaker. As the
X-value increases, the location of the sound moves from the left speaker
to both speakers, and then finally to the right speaker only.)
•
The duration of the tone played for each point can be adjusted from the
Preferences menu. The default setting is 1 second.
•
For negative values of the Y-coordinate, white noise is mixed with the
tone. This setting can be changed in Orion Preferences.
•
For playback of the entire equation, tones are generated in sequence
starting from the minimum X-coordinate value to the maximum X-
