MATLAB: How to add single quotes ‘ ‘ in a string

signal processing

I am trying to add into my signal 2 quote marks. for example:

signal.wav and I would like to change it likes this: 'signal.wav'

I have done this so far:

a=strcat(signal_data,'.wav'); which gives me a=signal.wav

bear in mind that the signal name is keep chaning as it is in loop.

signal.wav

fun.wav

example.wav

Not sure why you would want something like that. Following works

signal_data = 'signal';
a=strcat('''', signal_data,'.wav''');

Result

>> disp(a)
'signal.wav'

Hi Adnan,

You can accomplish this with the reverberator object in Audio Toolbox:

https://www.mathworks.com/help/audio/ref/reverberator-system-object.html

Here is an example where you read a signal from a file and add reverb to it:

[audioIn, fs] = audioread('speech_dft.mp3');
r = reverberator('SampleRate',fs);
audioOut = r(audioIn);
sound(audioOut,fs)

See the ref page for information about reverberation parameters you can set.

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.
