Object for recording audio - MATLAB - MathWorks
https://www.mathworks.com/help/matlab/ref/audiorecorder.html
Description Use an audiorecorder object to record audio data from an input device such as a microphone for processing in MATLAB ®. The audiorecorder object contains properties that enable additional flexibility during recording. For example, you can pause, resume, or define callbacks using the audiorecorder object functions.

Create an audiorecorder object. Call the record or recordblocking method, where: record returns immediate control to the calling function or the command prompt even as recording proceeds. Specify the length of the recording in seconds, or end the recording with the stop method. Optionally, call the pause and resume methods.

Looking at the example in the documentation I would recommend trying to call getaudiodata(r) in your loop rather than with the CallBack. So something like this: % assume fs,winsize,winshift is given. T = 0.1; % in seconds samples = cell{100,1}; r = audiorecorder(fs,16,1); k=1; r.TimerPeriod = 0.1; r.StopFcn = 'disp(''Completed sample '', k)'; r.TimerFcn = …

Now, in the start push button callback, we would do something like function recordbutton_ClickedCallback(hObject, eventdata, handles) record(handles.recorder); Since we can access the audio recorder through the recorder field of handles, we do so and start the recording. We would do something similar for the stop button, replacing record with stop.

https://it.mathworks.com/matlabcentral/answers/573193-how-can-i-record-an-audio-from-a-tuggle-button-in-the-guide
I don´t know if I can put the "audiorecorder object" in the handles, the code below is in the CallBack function of tuggle button , when I push the toggle button it gives me an error, it says "record is empty". I use "getaudiodata" because I also have to modify the voice. I need that record the voice, stop the record and save that in a vector.
