Lowpass-filter signals - MATLAB lowpass
https://www.mathworks.com/help/signal/ref/lowpass.html
y = lowpass(x,wpass) filters the input signal x using a lowpass filter with normalized passband frequency wpass in units of π rad/sample. lowpass uses a minimum-order filter with a stopband attenuation of 60 dB and compensates for the delay introduced by the filter. If x is a matrix, the function filters each column independently.

https://stackoverflow.com/questions/21935871/low-pass-filter-in-matlab-returning-nan-values
I've been able to load some audiofiles into MATLAB, play them, mix them and synthesize signals. Now, however, I want to extract the base similar to an equalizer or a low-pass filter in an audio editing program. I know MATLAB has a lot of filters and built-in filter design tools; I just want to add a simple low-pass filter, though.

Low pass filtering. In low pass filtering, we assume that our signal has been contaminated by the white Gaussian noise and it can be reduced by this low pass filter. Matlab code for low pass filter (LPF) We import the audio signal into Matlab by executing the code below:

This resides in the low frequency range of the spectrum, whereas the voice has a more higher frequency. As such, we can apply a bandpass filter to get rid of the low noise, capture most of the voice, and any noisy frequencies on the higher side will get cancelled as well. Here are the steps that I did: Read in the audio file using audioread.
