screen. An imaginary cursor moves from left to right and plays average
pitch of each column.
Important Note:
When using
Graph screen Sonograph mode
, all information
present in the sweep region is included in the sweep sound. To avoid
nongraphical information (axis, coordinate information) in sweep sound, select
Axis Off
, and then
Coord Off
from the
Format menu
. To avoid nongraphical
information (cursor) in sweep sound, press the
Graph
or
Enter
keys.
When using Sonograph for either Density or Average, there are four possible
sweep region cursor sizes:
1. Full
2. One-half
3. One-fourth
4. One-eighth
The corresponding amount of the screen from top to bottom will be swept
depending on the size of sweep cursor chosen. Move the sweep cursor by
pressing the Orion
Up
and
Down
arrow keys. If you are at the bottom of the
screen and the bandwidth is set to one-forth screen, the sweep cursor moves by
fourths. If you press the Orion
Up
arrow key, it moves up by one-forth from the
bottom. If you press the Orion
Down
arrow key, the sweep cursor will wrap to the
top and sweep the top one-fourth of the screen. Once you move the sweep
cursor, the graph will be swept and the region selected will be played.
For smaller and bigger bandwidths, you can resize the bandwidth by pressing the
Orion
Left
and
Right
arrow keys, respectively.
Variable Band Location
is another way to move the sweep location. Pressing the
Home
key will move the sweep cursor to the point where the calculator cursor is
and the width of the band at that location will be swept and played.
