Filtering out a Specific Sound from a Audio File
https://www.mathworks.com/matlabcentral/answers/336881-filtering-out-a-specific-sound-from-a-audio-file
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.

The following is the syntax for using fir2: [h] = fir2 (m, [0,lowF,highF,1], [dcA,lowA,highA,nyqA]) Input Variables: m – filter order, length of impulse response. Example: 10. lowF, highF – normalized cut-off frequencies. dcA, lowA, highA, nyqA – linear amplitude for corresponding frequencies. Output Variable:

In this video, some basic processing of Audio signals is presented. Here, it will be shown that how one can implement an FIR low pass filter to remove white Gaussian noise present in an audio signal. Also to produce various sound effects such as Pop, Rock, Jazz etc., a graphic equalizer is implemented. Few other popular sound effects such as Echo, Flange and Reverb …
