3. In the selection status fields on the playbar (at the lower right-hand side of
the data window) you should see the values of 0, 220,506, and 220,507.
This means that the first selected sample (Selection Left) is sample 0, the last
selected sample (Selection Right) is 220,506, and the total number of samples
in the selection (Selection Length) is 220,507.
4. Now select the Time option from Status Format under the Options menu.You
will see that all these values change to values specified in hours, minutes,
and seconds rather than samples. You can see that a sound containing
220,507 samples with a sample rate of 44,100 Hz will play for about 5.0
seconds. You can experiment with each of the status formats to see how
each format is displayed.
CONFIGURING FRAMES AND MEASURES & BEATS
When setting the status format to Frames or Measures & Beats, you customize how
these values are displayed.The Edit Frame Rate dialog in the Special menu allows
you to change the frames per second. In the Edit Tempo dialog from the Special
menu, you can specify the Beats per minute and Beats per measure values used to
calculate measures and beats. The default values for Frames and Beats are set on
the Status page in the Preferences folder (Options menu).
MAGNIFICATION AND ZOOMING
When sound data is drawn on the screen, it is necessary to represent many
samples of data for each horizontal point on the screen. There are almost
always many more samples in a sound file than there are horizontal points
(pixels) on the screen. Depending on the editing operations you need to use,
you may want to view the entire file at once, or you may want to look at only
a small portion in greater detail. This is where the magnification, or zoom,
ratio comes in.
TIME RULER ZOOMING
In the bottom right corner of the data window, just above the data window
playbar, is the current time magnification ratio. The Zoom Ratio defines how
many samples of sound data are squeezed into each horizontal point on the
screen. This setting is shown as a value of 1:XX , where XX is the number of
samples represented by each horizontal point on the screen.
