Performing an echo
Echoes are useful effects which are often difficult to record naturally.
Using Audio Editor, however, you can overcome such recording
limitations and produce echoes that sound as if you are in a canyon or at a
baseball game.
To create an echo quickly, click either one of the Echo commands available
in the Effect menu. Or, to customize one of those commands, click Effect:
Echo. This opens the Echo dialog box which allows you to define the three
characteristics of each echo command: Delay, Decay, and Bound. Delay is
the length of time that passes before you hear an echo, while Decay
accounts for the loss of sound in each repetition. Bound determines the next
round of repetition and is repeated until the echo fades away entirely. Below
is a description of the characteristics for each of the echo commands:
• Long Echo has a long delay and a strong decay which results in longer
repetitions, though it fades away faster.
• Long Repeat has a short delay and weak decay, therefore making the
echo last longer (though each repetition comes in faster cycles).
• Resonance has a short delay with little decay and a very short bound.
This results in a quick and fast echo, sort of like an "audio shadow."
• Stadium echo is very similar to Long Echo but starts sooner and ends
faster.
