[. . . ] Besides just echoes, you can add filtered versions of echoes by entering the minimum and maximum frequencies to echo. To echo all frequencies outside the range, add a full spectrum echo (e. g. from 0Hz to 22050Hz) at a specific delay, then add another echo at the same delay, but with different minimum and maximum values, and the opposite Left and Right percentages (e. g. at -100% instead of 100%).
· Delay: This parameter sets the amount (in milliseconds) by which samples are delayed. For pre-echoes, place at least
one echo that is full spectrum (Minimum=0Hz, Maximum=22050Hz) at a larger delay (like 1000ms). Then any echo placed before 1000ms will be a pre-echo.
· Left : This setting specifies the left volume (in percent) at which to make the echo or selection being added to the
impulse.
· Right: This setting specifies the right volume (in percent) at which to make the echo or selection being added to the
impulse.
Global Settings These settings effect how the given impulse will be used during convolution. · Volume: If the convoluted audio comes out too soft or too loud, enter an appropriate value to amplify or attenuate
the audio.
· Shift: This value is generally set to one-half the FIR Size when building impulses from scratch, to compensate for the
delay incurred when the minimum delay used was only one-half the FIR size. Adjust this shift setting if you find that the convoluted audio is migrating too far to the right with respect to the original audio.

Effects Menu Edit View
View Settings These settings affect the impulse display. · Left: Select this button to enable display of the impulse for the left channel only. · Right: Click this button to enable display of the impulse for the right channel only. · View: Both Selecting this button enables display of the impulse for both the right and left channels. · Normalized View: If this option is checked, the impulse's amplitude is displayed so that it exactly fits in the display
vertically.
Preview Press the Preview button to audition the current Convolution setting before you apply it to the waveform. Since Adobe Audition's Previews are dynamic, this gives you the opportunity to make and hear processing adjustments as the selection is continuously played.
Distortion
Use this function to create effects such as a blown car speaker, a muffled microphone, and an overdriven amp. (Of course, it's great for adding fuzz to guitar licks to get that "authentic" heavy metal sound. )
Distortion dialog Positive/Negative Tabs You can specify separate distortion curves for positive and negative sample values. Select the tab
corresponding to the distortion curve you want to display. If the Symmetric box is checked, these tabs become inactive (and are marked Symmetric).
ADOBE AUDITION 179 User Guide
Copy from Positive Press the Copy from Positive button (available in the Negative tab) to copy the positive curve to the
Negative window.
Symmetric If Symmetric is checked, the positive and negative curves are identical. To specify separate Positive and
Negative curves, uncheck Symmetric and choose the appropriate tab.
Distortion Graph This graph depicts the input sample value in dB along the x-axis (left and right) and the output sample
value in dB along the y-axis (up and down). A line that flows directly from the lower-left to the upper-right (which is the default) depicts a signal that's been left untouched, since every input value goes to the exact matching output value. Adjusting the shape of this line will adjust the input to output assignments. The readout below the graph displays the current input and output sample values that are under your mouse pointer. Note: For more information about Adobe Audition's graph controls (such as how to add and remove control points), see the "Looking at the Work Area" chapter.
Spline Curves Check this option to generate a smoother, best fit curve instead of a straight line between control points
on the graph. When you use Spline Curves, the line won't ordinarily travel directly through the control points; rather, the points control the shape of this curve. [. . . ] Unity Gain When a device is set to Unity Gain, it means its output will be at its specified line level. Because there are
different line levels (-10 dBV and +4 dBu being the most common), a device could take a voltage of one level, turn it up to a different level, and pass that as its unity gain.
VOC This is the Sound Blaster and Sound Blaster Pro voice file format. Mono files can have a sample rate of up to 44. 1 kHz, and stereo up to 22 kHz. If the file you're loading contains loops and silence blocks, they'll be expanded while loading. [. . . ]
