Getting Optimum Results
with SoundReplacer
Getting optimum results with SoundReplacer
generally means making sure that the audio
events in the replacement audio file have accu-
rate timing in relation to the source audio. The
techniques given here help ensure this.
Using Peak Align in
SoundReplacer
Proper use of the Peak Align feature can signifi-
cantly improve the results of sound replace-
ment. Since turning Peak Align on or off con-
trols how SoundReplacer aligns the replacement
audio with the source audio, it will significantly
affect the timing of audio events in the replace-
ment file.
In general:
 Turn on Peak Align if you are replacing drum
or percussion sounds whose peak level occurs at
the initial attack.
 Turn off Peak Align if you are replacing
sounds whose peak level occurs somewhere after
the initial attack. Peak Align should also be
turned off if the sounds you are replacing are not
drum or percussion sounds.
To illustrate why Peak Align makes a difference,
look at the following two illustrations.
The first figure shows a fast-peaking kick drum
whose peak level occurs at its initial attack.
The second figure shows a slower-peaking kick
drum whose peak level occurs after its initial at-
tack.
If you turn on Peak Align and attempt to replace
the fast-peaking kick with the slow-peaking kick
(or vice-versa), SoundReplacer will align their
peaks—which occur at different points in the
sound. The audible result would be that the re-
placement audio file (slow-peaking kick) would
trigger too early.
