Syntax

visualize(equalizer)
visualize(equalizer,NFFT)
hvsz = visualize(___)

Description

visualize(equalizer) plots the magnitude response of the graphicEQ object, equalizer. The plot is updated automatically when properties of the object change.

visualize(equalizer,NFFT) specifies an N-point FFT used to calculate the magnitude response.

example

hvsz = visualize(___) returns a handle to the visualizer as a dsp.DynamicFilterVisualizer object when called with any of the previous syntaxes.

Examples

Open Live Script

Create a default graphicEQ System object™ and then call visualize.

equalizer = graphicEQ;
visualize(equalizer)

Set the gains of the graphic equalizer to new values. The visualization of the magnitude response updates automatically.

equalizer.Gains = [-1,1,2,3,3,2,-10,5,5,-10];

Input Arguments
