Highpass-filter the signal to separate the melody from the accompaniment. Specify a passband frequency of 450 Hz. Plot the original and filtered signals in the time and frequency domains. hong = highpass (song,450,fs); % To hear, type sound (hong,fs) highpass (song,450,fs) Plot the spectrogram of the melody.
High-Pass Filter - MATLAB & Simulink - MathWorks
https://www.mathworks.com/discovery/high-pass-filter.html
Design high-pass filters using MATLAB. A high-pass filter attenuates signals below a cutoff frequency (the stopband) and allows signals above the cutoff frequency (the passband). The amount of attenuation depends on the design of the filter. High-pass filters are often used to clean up low-frequency noise, remove humming sounds in audio signals, redirect higher …

Matlab code for low pass filter (LPF) We import the audio signal into Matlab by executing the code below: % Program to implement a LPR(FIR) with cutoff 8kHz to denoise audio signal. [fileName, pathName] = uigetfile('*.*', 'select the input audio'); [x, Fs] = audioread(num2str(fileName)); % x is the audio samples and Fs is the sampling rate.

I am trying to process an audio file in Matlab by filtering out all frequencies except those within $\pm 25\ Hz$ of $523\ Hz$ (as well as its harmonics up to the Nyquist). The resulting waveform should look like the green wave displayed below (blue being the original): However, my resulting waveform is entirely zero: Here is the simple code I ...
