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.

1. Create a DataAcquisition with directsound as the vendor and add an audio output channel to it. dd = daq ( "directsound" ); nch = 6; addoutput (dd, "Audio2", 1:nch, "Audio" ); 2. Update the generation scan rate to match the audio sampling rate. dd.Rate = Fs;

Edited: W. Owen Brimijoin on 20 Jan 2015. Simple mixing is just adding. y3 = y1 + y2; If you want to control the level of each within the mix, then you need to adjust them as follows: y3 = (y1*y1_level) + (y2*y2_level); where yx_level is …

How to add an echo effect to an audio signal using Matlab
https://ashanpeiris.blogspot.com/2015/03/how-to-add-echo-effect-to-audio-signal.html
Write a function called echo_gen that adds an echo effect to an audio recording. The function is to be called like this: output = echo_gen(input, fs, delay, amp); where input is a column vector with values between -1 and 1 representing a time series of digitized sound data. The input argument fs is the sampling rate.

Use the command clear sound to end playing your chosen audio file/signal. File_Name = "Audio.mp3"; Audio = audioread(File_Name); Original_Signal = Audio(:,1); Signal_To_Noise_Ratio = 20; Noisy_Signal = awgn(Original_Signal,Signal_To_Noise_Ratio); %Playing back at the sampling frequency, Fs% Fs = 44100; sound(Noisy_Signal,Fs);
How to concentate multiple audio signals in to one instance
https://it.mathworks.com/matlabcentral/answers/1614235-how-to-concentate-multiple-audio-signals-in-to-one-instance
signalvec = [signal1, signal2]; now I could go: concattedsignal = cat (2,signalvec (1),signalvec (2); but it doesn't help me if the array gets bigger. I tried: for i = 1 : length (signalvec) concattedsignal = cat (2,signalvec (i)); end. but this will always just give me the last instance of the array.
