Chapter 12: SoundReplacer 109
If you change the audio selection on the source
track, click Update to update the waveform dis-
play. If Auto Update is selected, SoundReplacer
automatically updates the waveform display
each time you make a new selection or begin
playback.
Trigger Threshold
The color-coded Trigger Threshold sliders set a
total of three amplitude zones (one for each re-
placement audio file) for triggering replacement
samples:
• The yellow slider represents amplitude zone 1,
the lowest-level trigger.
• The red slider represents amplitude zone 2,
the middle-level trigger.
• The blue slider represents amplitude zone 3,
the highest-level trigger.
With a replacement sample loaded, drag the
Threshold slider to the desired amplitude level.
Color-coded trigger markers will appear in the
Waveform at points where the source audio sig-
nal exceeds the threshold set for that amplitude
zone. The replacement sample will be triggered
at these points.
The color of the Trigger markers correspond to
the matching Threshold slider. This allows you
to see at a glance which replacement samples
will be triggered and where they will be trig-
gered.
Load/Unload Sound
Clicking the Load/Unload Sound icons loads or
unloads replacement samples for each of the
three trigger threshold amplitude zones. Click-
ing the Floppy Disk icon loads a new sample (or
replaces the current sample). Clicking the Trash
Can icon unloads the current sample.
If you frequently change selections or start
and stop playback, turn off Auto Update to
prevent too-frequent redraws.
Threshold controls
If you zoom the waveform display below a
specific Trigger Threshold slider’s ampli-
tude zone, the slider will be temporarily un-
available. To access the slider again, zoom
back out to an appropriate magnification
level.
Load/Unload Sound
SoundReplacer does not perform a sample
rate conversion before loading replacement
samples if they are at a different sample
rate from the session. Replacement samples
should be at the same sample rate as the
session, otherwise they will playback at the
wrong speed and pitch.
