ADOBE AUDITION 145 User Guide Q (Bandwidth) Tab The Q (bandwidth) window's graph is used to adjust the amount of Q used by the Dynamic EQ effect. The x-axis (horizontal) ruler represents the length of the selection, while the y-axis (vertical) ruler represents the frequency that's boosted or cut. Spline Curves Check this box - which appears in each of the Gain, Frequency, and Q (bandwidth) tabbed windows - 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. Instead, 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). Flat Press the Flat button - which appears in each of the Gain, Frequency, and Q (bandwidth) tabbed windows - to reset the curve to its default state of an unchanged signal, removing all Control Points. Filter Type Three types of filters are offered: • Low Pass passes the low frequencies while rejecting (or removing) high frequencies. • High Pass passes high frequencies and removes low frequencies. • Band Pass: This mode preserves a range of frequencies (that is, a band) while removing all other frequencies. Loop Graphs When this box is unchecked, the graphs are the same length as your selection, so the dynamic changes to your equalization are graphed across the whole selection. If you check Loop Graphs, the graphs are only as long as specified in the Graph Duration field (which is enabled when Loop Graphs is checked), so they loop repeatedly over the course of the selection. Presets Adobe Audition comes with several Dynamic EQ 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 Dynamic EQ 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. Automated When using Dynamic EQ as a real-time effect in Multitrack View, it supports parameter automation. • Check the Automated box in the Gain section of the Multitrack View version of the Dynamic EQ dialog to draw the Gain curve using a yellow envelope on waveform blocks. • Check the Automated box in the Frequency section of the Multitrack View version of the Dynamic EQ dialog to draw the Frequency curve using a pink envelope on waveform blocks. Note: You must have View > Show FX Parameter Envelopes in Multitrack View turned on in order to use parameter automation.
