Example of loading audio file and playing audio in MATLAB (2017a): % Read the audio file and store the audio in data and sampling rate into fs [data, fs] = audioread ('test3_Q3.wav'); % Play audio file. player = audioplayer (data,fs); play (player); a.) Use the DFT to figure out the tone frequencies (at least approximately).

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.
