ADOBE AUDITION 121 User Guide By reducing the delay times further down into the 1-14 millisecond range, you can spatially locate a mono sound (a sound with the same information for both the left and right channels) so that it appears as though the sound is coming from the left or the right side, even though the actual volume levels for left and right of the wave are identical. Delay These sliders allow you to adjust the desired delay for both the left and right channels up to plus or minus 500 milliseconds. Entering a negative number means that you can move a channel ahead in time instead of delaying it. For instance, if you enter 200 milliseconds for the left channel, the delayed portion of the affected waveform will actually be heard before the original part. Mixing Move the Mixing sliders to set the percentage of Delayed (wet) signal and unprocessed Original (dry) signal to be mixed into the final output. A value of 50 will mix the two evenly. Invert If this box is checked, the positive values of the selected waveform become negative. This means that cancellation will occur when you mix the inverted and original waveform. Inverting the delayed signal can be used for special effects, such as creating a quick-and-dirty comb filter. Presets Adobe Audition provides several Delay presets. More information on presets can be found in the "Looking at the Work Area" chapter. Preview Press the Preview button to audition the current Delay setting before you apply it to the waveform. The selection is looped until you press the Stop button. Since Adobe Audition's Previews are dynamic, this gives you the opportunity to make and hear processing adjustments as the selection is continuously played. Check the Bypass box to hear the waveform without any applied Delay effects for a quick "before and after" comparison. Make sure there is enough silence at the end of the waveform for the delay trails to complete. If the delay abruptly cuts off before it fully decays, undo the Delay effect, add several seconds of silence using Adobe Audition's Generate > Silence command, and rerun the Delay effect. Dynamic Delay Dynamic Delay allows you to change the amount of delay over the length of the waveform. For instance, for the first five seconds of an audio file you can have a 2 millisecond delay, for the next 15 seconds you could have a 20 millisecond delay, for the following 10 seconds the delay could be at 7 milliseconds, and so on.
