Center Frequencies and High/Low Frequency Limits for Octave
Octave Bands: The audio spectrum from ~ 20 Hz to ~ 20 KHz can be divided up into ~ 11 octave |
What happens if you convert a narrow frequency band to octave?
An important part of the information is however lost when converting results from narrow frequency bands to octave or one-third octave frequency bands. Narrow frequency bands are bands with a constant frequency step much smaller than the frequency spectrum.
How do I design a full octave-band Filter?
Design a full octave-band filter using octaveFilter. BW = "1 octave"; % Bandwidth N = 8; % Filter order F0 = 1000; % Center frequency (Hz) Fs = 48000; % Sampling frequency (Hz) of = octaveFilter (FilterOrder=N,CenterFrequency=F0, ... Bandwidth=BW,SampleRate=Fs); Visualize the magnitude response of the filter.
