Description

AudioFilter adjusts the frequency content of audio streams. It provides one Input pin and one Output pin which can be connected to/from by Wires. AudioFilter uses its FilterType, Gain, and Q properties to determine what to do around a particular cutoff Frequency.

FilterType

TypeDefault
AudioFilterTypePeak

The type of frequency response curve that will be used to filter the audio signal. Each type of curve affects the frequency content of the audio in different ways.

History 1

Frequency

TypeDefault
float2000

The central frequency in hertz of the curve represented by the filter. Generally, adjusting this value up or down corresponds to a horizontal shift in the overall frequency curve. Ranges from 20 to 22000.

Gain

TypeDefault
float0

The gain value in decibels used to determine the volume level of the curve represented by the filter. Only applies when the FilterType is Peak, LowShelf, or HighShelf. Ranges from -30 to 30.

GetConnectedWires

Parameters (1)
pinstring
Returns (1)
Instances

Returns an array of Wires that are connected to the specified pin. AudioFilter has one "Input" pin and one "Output" pin.

GetGainAt

Parameters (1)
frequencyfloat
Returns (1)
float

Returns the gain value, in decibels, of the frequency response curve represented by the filter at the given frequency, in hertz. This can be used to sample the exact shape of the filter in key places or as a whole.

Q

TypeDefault
float0.707000017

The quality value used to determine the slope or resonance of the curve represented by the filter. Only applies when the FilterType is Peak, Lowpass[x]dB, Highpass[x]dB, Bandpass, or Notch. Ranges from 0.1 to 10.

For FilterType values of Lowpass12dB and Highpass12dB, a Q value of sqrt(2) / 2, or 0.707, corresponds to a flat filter at a 12dB/octave slope.
