The Cut block contains one high-cut and one low-cut filter. High-cut and Low-cut filters remove (cut out) frequencies above or below their frequency setting, thereby limiting the upper or lower frequency range. Audio systems typically do not require true 20 Hz to 20,000 Hz frequency response. For example, typical speech has a frequency range of 200 Hz to 4 kHz. Cutting frequencies below 200 Hz eliminates low frequency noise picked up by microphones (HVAC systems, thumps, etc) and helps tame plosives in speech. Cutting frequencies above 4 kHz helps remove unwanted high frequency noise, such as white noise from fans and fountains.
note: A bypassed filter’s magnitude/phase response and frequency handle are hidden in the graph. By default the graph only displays the composite magnitude response (the total result of every filter in the block).

|Graphical representation of filters. Shows Magnitude vs. Frequency by default. Use the brown handles to adjust a filter's frequency. Use View options to change graph content.|
|View options||Selecting Magnitude (selected by default) displays the filters' Magnitude on the graph. Selecting Phase (deselected by default) displays the filters' phase response on the graph. Selecting Composite (selected by default) displays frequency handles for both filters on the graph. Selecting Individual (deselected by default) displays the individual contribution of the selected filter.|
|Frequency control||Displays the current corner frequency of the selected filter. Change the frequency by moving the slider or editing the frequency value in the edit box.|
|Type and Slope/Order||Displays the Type and Slope/Order (alignment) associated with the selected filter. To select a different option, click the down arrow and choose from the list that appears.|
|Bypass (above Table View)||Selecting this checkbox bypasses the selected filter, which effectively turns the filter into a wire.|
|Filter Table View||Displays the Frequency, Type, and Slope/Order for each filter. To select a filter, click its row in the table. You can also bypass a filter by selecting its associated Bypass checkbox.|
|Bypass All||Selecting this checkbox bypasses both filters.|
