A simple .
Y axis: shows amplitude from -18 dB to 18 dB (displayed linearly with respect to decibels).
Analyze:
In (Button): toggle display of input signal on graph (before signal alterations)
Out (Button): toggle display of output signal on graph (after signal alterations)
You'll notice that there are 8 columns with numbers 1-8, these represent 8 different filters (of 5 filter types) that can be used to alter the input signal.
Row of Knobs:
Top Row: adjusts the Cutoff Frequency of their respective filter
Bottom Row: adjusts the Resonance (Filters 1, 2, 7, and 8) and Bandwidth (Filters 3, 4, 5, and 6) of their respective filters.
1: This is a Highpass Filter, it removes frequencies below the cutoff frequency.
2: This is Low Shelf Filter, it can either boost or reduce frequencies below the cutoff frequency.
3 through 6: These are Peak Filters, they can either boost or reduce frequencies around the cutoff frequency.
7: This is a High Shelf Filter, it can either boost or reduce frequencies above the cutoff frequency.
8: This is a Lowpass Filter, it removes frequencies above the cutoff frequency.
In (Slider): adjusts the gain of the input signal.
Out (Slider): adjusts the gain of the output signal.
X axis: shows frequencies from 20 Hz to 20,000 Hz, divided into (this makes the X axis appear nonlinear).
: toggles their respective filters on/off. (Notice the symbols next to the numbers)
: adjusts slope of Highpass (1) and Lowpass (8) Filters, respective to each filter.
: adjusts gain of Filters 2 through 7, respective to each Filter.
