type

Summary

The type of BiquadFilterNode (filtering algorithm) the node is implementing.

var result = BiquadFilterNode.type;
BiquadFilterNode.type = value;

Returns an object of type unsigned shortunsigned short

Uses one of the following constant values:

LOWPASS (0) (default), a standard second-order resonant lowpass filter with 12dB/octave rolloff;
HIGHPASS (1), a standard second-order resonant highpass filter with 12dB/octave rolloff;
BANDPASS (2), a second-order bandpass filter;
LOWSHELF (3), a second-order lowshelf filter;
HIGHSHELF (4), a second-order highshelf filter;
PEAKING (5), a boost (or attenuation) to a range of frequencies;
NOTCH (6), restricting a set of frequencies;
ALLPASS (7), a second-order allpass filter.

var audioCtx = new AudioContext();
var biquadFilter = audioCtx.createBiquadFilter();
biquadfilter.type = 'lowpass';
