getFilters

Get crossover band filters

Since R2024b

Syntax

filters = getFilters(crossFilt)

Description

filters = getFilters(crossFilt) returns the individual filter objects for each band in the crossoverFilter object.

Examples

Get Band Filters from crossoverFilter Object

Create a crossoverFilter object with 2 crossovers (3 bands), crossover frequencies at 500 Hz and 1 kHz, and a slope of 18 dB/octave.

fs = 44100;
crossFilt = crossoverFilter( ...
    NumCrossovers=2, ...
    CrossoverFrequencies=[500,1000], ...
    CrossoverSlopes=18, ...
    SampleRate=fs);

Call the getFilters function on the object to get the individual band filter objects.

filters = getFilters(crossFilt)

filters=1×3 cell array
    {1x1 dsp.FilterCascade}    {1x1 dsp.FilterCascade}    {1x1 dsp.FilterCascade}

Use filterAnalyzer to view and analyze the individual filters that make up the crossoverFilter object.

filterAnalyzer(filters{1},filters{2},filters{3}, ...
    SampleRates=fs, ...
    FrequencyScale="log", ...
    FilterNames=["Band1","Band2","Band3"])

Input Arguments

crossFilt — Crossover filter object

crossoverFilter object

Crossover filter, specified as a crossoverFilter object.

Output Arguments

filters — Band filters

cell array of filter objects

Band filters of the crossover filter specified by crossFilt, specified as a cell array of N+1 filter objects, where N is NumCrossovers. The filter objects are returned as dsp.SOSFilter or dsp.FilterCascade objects. See Algorithms for more information about the design of the band filters.
