10. Click the Sound player’s Play button.
If you have stereo speakers or headphones connected, you should now hear two distinct tones –
a mid-range tone from the left speaker (connected to Output
CH1 ) and a higher pitched tone
from the right speaker (connected to Output CH2 ).
Hint: If you happen to have a ‘surround sound’ speaker setup with front and rear speakers, you
will also hear another even lower tone coming from the rear speakers.
11. The VU meter for Sound in the Internal Audio tab will show matching levels for all four
input channels.
12. Next, drag the Balance slider all the way to the left. As you do so, observe that the level
shown for channel 2 and channel 4 are gradually reduced. At the extreme left position,
these two channels are completely silent. Only the mid-range tone (on channel 1) is
heard (in a stereo environment), and only from the left speaker at that – see Figure 37.
Figure 37
Moving the slider to the right (of center) has the opposite effect, reducing channels 1
and 3 – doing so without any effect on the other 2 channels. At the extreme right
position, only the mid-range tone from the DDR file is audible (and only from the right
speaker).
The lesson here is that – unlike Mono , considered shortly, or Pan – Balance does not ‘move’
audio from one channel to another. You cannot use Balance to ‘blend’ channel 1 with channel 2,
for example. Balance regulates the levels for one pair of channels (1 and 3, or 2 and 4) at a time,
and does not affect the other pair in doing so.
