[. . . ] 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. 178 CHAPTER 8 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. To get the curve closer to a control point, click to create more control points near the point in question. The more control points there are clustered together, the closer the spline curve will be to those points. Use Spline Curves when you want very smooth curves instead of straight lines (with their discontinuities at the control points). Presets Adobe Audition comes with several Distortion 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 Distortion 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. Music Adobe Audition's Music function can use any highlighted selection as a "voice" to synthesize music or harmonize a wave using a particular chord. [. . . ] In this case, the term usage is referencing sound waves, and is being used in an acoustical sense. Waveform Block Any waveform entry in the Multitrack environment. A Waveform Block may be an actual represen- tation of a waveform, an Image (a pointer to another waveform block), a copy of another waveform, a spliced section of another Waveform Block, etc. You can right-click on a Waveform Block for a menu containing editing commands, or double click on it to "jump into" its source in the Edit View. Wave Display The Wave Display is the part of Adobe Audition's Edit View in which you view and manipulate audio data. By default this audio material is in the shape of a waveform, but it can be displayed as spectral data by choosing the View > Spectral View option. [. . . ]
