First load the signal into MATLAB using the command wavread (using older MATLAB versions) and audioread (using newer versions) which you can read more about in the MATLAB help file. Example of loading audio file and playing audio in MATLAB (2017a): a.) Use the DFT to figure out the tone frequencies (at least approximately).

The first step is to design a filter to obtain the A and B vector coefficients.Then use the Butter function, for instance to obtain your signal(type Butter in your Matlab command window and you will find many other type of filters). Once you have obtained the B and A vector coefficients you can filter your signal using the function filter.

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.

Audio Signal Filtering. By Dhruv Lamba. Background. Audio signals in the digital world are simply 1-D signals that contain the values of the sampled sound v/s an index, say k. Consider the diaphragm on a microphone, that vibrates every time a sound impinges on it.
