MATLAB: How to play and merge/mix 2 wav files

buttonguimixplaysoundtwowav

Hi,

Basically I want to merge the two wav files so that both music or voice annotates and play the a sound(i.e., you can hear both the voice and the music), and than save as a new wav file.

I am thinking of creating a merge/play button, but I do not know how to go about it. Any help would be much appreciated. Thank you.

Please review http://www.mathworks.com/matlabcentral/answers/313351-how-can-i-merge-two-audio-files-mp3-wav-to-be-able-to-hear-them-playing-both-together-in-the-same for information on merging sounds.

With regards to a Merge/Play button: create the button ahead of time in GUIDE, but set the default properties for it as 'Visible', 'off' . Then, in your code, as soon as you have verified that you have both inputs so the conditions are right for allowing merging, set the button 'Visible' property to 'on'.

MATLAB: Audio file (.wav) being overwritten

You have

speech = ('coch4.wav');
speech2 = speech;

So your speech2 filename is the same as your speech filename.

[y,Fs]=audioread(speech2); %don't use wavread or audioread

So you read from coch4.wav via speech2 filename

audiowrite(speech, speech_trimmed, 44100);

and then you write to the file name given by speech, which is the same as the filename given by speech2, so you are writing to the same file that you read the data from.

MATLAB: Need help with cutting 37 seconds off from start of wav file.

[y,fs] = audioread(filename);
filename = 'C:\Users\ajbaf\Music\mlabpost\wm7001.wav';
y(1:37*fs,:) = []; %% this deletes the matrix elements corresponding to the index range 1:37*fs
y(end-3.65*fs:end,:) = [];
wavFileName = 'C:\Users\ajbaf\Music\mlabpost\wmr.wav';
audiowrite(wavFileName, y,fs);
