Paragraphic EQ |
The Paragraphic EQ is a set of six very flexible parametric filters. Four independent band filters allow you to boost or attenuate specific frequency ranges. In addition, two shelving filters let you control the amount of low and high frequencies in your recordings. A Gain vs. Frequency graph shows the overall effect of the combined filters, making it easier to visualize the final sound.
Removing
very low and inaudible frequencies after recording eliminates any DC
offset and gives your sounds more headroom for audible frequencies.
Open the Sonic Foundry Paragraphic EQ dialog.
Choose a preset from the Name drop-down list, or adjust the controls as desired:
a. Drag the Dry Out fader to set the level of the unprocessed signal mixed into the output.
b. Drag the Wet Out fader to set the level of the processed signal mixed into the output.
c. Drag the Gain fader to set the amount of boost or cut for the band. To quickly disable a band, set the Gain to 0.0 dB by double-clicking on the fader handle.
d. Drag the Width slider to specify the number of octaves (centered on the selected frequency) that will be affected by the filtering. Use a high value to affect a greater range of frequencies and a low value for a more selective (notch) filter.
e. Drag the Center frequency slider to specify the center of the selected frequency band.
f. Select the Enable low-shelf check box to attenuate or boost frequencies below the low-shelf cutoff frequency. The low-shelf cutoff frequency and gain are determined by the sliders to the right of the Enable low-shelf check box.
g. Select the Enable high-shelf check box to attenuate or boost frequencies above the high-shelf cutoff frequency. The high-shelf cutoff frequency and gain are determined by the sliders to the right of the Enable high-shelf check box.
