Finally, if you make volume adjustments within the clip,
the line consists of sloping segments that meet at
volume adjustment handles.
Unlike the waveform graph, or the adjustment lines for
balance and fade (see below), the volume adjustment
line is scaled logarithmically. Perceived volume varies
logarithmically with the strength of an audio signal, so
this feature allows the adjustment line to model more
accurately what you really hear. For instance, an
upward-sloping line segment will produce a smooth,
steady fade up from the starting to the ending level.
The green stereo balance line and the red front-back
balance (“fade”) line work similarly to the volume line,
except that in both cases the neutral position is the
vertical center of the clip, and the adjustment scale is
linear.
Raising the stereo balance line positions the audio
clip’s output further to the listener’s left, while
lowering it positions the clip further to the listener’s
right. Similarly, raising the fade line moves the clip
away from the listener, and lowering it brings the clip
towards the listener.
Note: You can only view and edit a clip’s fade line
when the Volume and balance tool is in surround
mode. The effect of adjusting the line can be previewed
only on systems where surround-sound playback is
available.
