Multi-Band Dynamics |
The Multi-Band Dynamics plug-in is essentially a compressor that only affects certain frequency bands. The possibilities for this type of compressor are endless, but the most common uses are for reducing sibilants (S sounds) and plosives (popping P sounds) or to tighten the bass in a mix without using EQ.
When
using this effect in applications that support multiple property
pages, users gain the ability to edit a total of four distinct bands.
Host applications will provide a means to switch between pages
enabling the user to custom define and bypass any of the bands.
Open the Sonic Foundry Multi-Band Dynamics dialog.
Choose a preset from the Name drop-down list, or adjust the controls as desired:
a. Drag the fader to set the level at which the dynamics processor begins acting on the signal. The selected frequency band will be compressed when it exceeds this level. You can select the Capture threshold check box to detect and update the threshold automatically.
You
will not be able to control the threshold when Capture
threshold is selected.
b. Drag the Amount slider to set the compression ratio applied to a band when it is above the threshold level. A high compression ratio means more gain reduction will be applied.
c. Drag the Gain fader to set the overall gain applied to a band after it has been compressed. Set the fader above 0 dB to compensate for the level lost due to compression.
d. Drag the Attack time slider to set the time, in milliseconds, required for the dynamics processor to start acting on the signal when the input level rises above the threshold.
e. Drag the Release time slider to set the time, in milliseconds, required for the dynamics processor to stop acting on the signal when the input level drops below the threshold.
f. Choose a setting from the Type drop-down list to specify the frequency band type:
Low-shelf |
Frequencies below the cut-off frequency will be compressed when using a low-shelf filter. When you select Low-shelf, drag the Below slider to set the cut-off frequency. |
Band-notch |
Frequencies surrounding the center frequency will be compressed when using a Band-notch filter. When you select Band-notch, drag the Center slider to set the center frequency, and drag the Width slider to set the frequency range of the band. |
High-shelf |
Frequencies above the cut-off frequency will be compressed when using a High-shelf filter. When you select High-shelf, drag the Above slider to set the cut-off frequency. |
When the Capture threshold check box is selected, the threshold for the current band is automatically detected and updated during preview. You will not be able to control the threshold when Capture threshold is enabled.
When the Band x bypass check box is selected, the current band will be grayed and will not affect the source material.
When the Solo check box is selected, the signal will be processed by the current band only, bypassing the processing parameters for other bands.
When a band is not bypassed, the meters represent the previewed audio passed through the filter. The red Gain Reduction meter shows the difference in gain between the input and output for each band.
Click the Input/Output button to toggle between monitoring the input or output signal of each band.
You
can right-click on any of the meters to change the selected dB range.
