Set InputDomain to "Frequency" and specify the window and overlap length used to transform time-domain audio to the frequency domain. Set LockPhase to true to increase the fidelity in the time-scaled output. alpha = 0.8; timeScaleModification = audioTimeScaler ( ...

The function is from an audio input which is in mono type chirp signal from 1kHz to 2kHz. I used the following code to import the audio to the workspace and to plot it; [x,fs]=audioread ('signal.wav'); %sound (x,fs); size ('signal.wav'); length (x); %whos x; %whos fs; T=length (x)./fs;%totalTime.
Time-stretch audio - MATLAB stretchAudio

Listen to the modified audio signal and plot it over time. The sample rate remains the same as the original audio, but the duration of the signal has increased. audioOut = stretchAudio(audioIn,0.75); t = (0:size(audioOut,1)-1)/fs; plot(t,audioOut) xlabel( 'Time (s)' ) ylabel( 'Amplitude' ) title( 'Modified Signal, Speedup Factor = 0.75' ) axis tight grid on

Scale data and play as sound - MATLAB soundsc
https://www.mathworks.com/help/matlab/ref/soundsc.html
Sample rate, in hertz, of audio data y, is specified as a positive number from 1000 through 384000. Valid values depend on both the sample rates permitted by MATLAB ® and the specific audio hardware on your system. MATLAB has a hard restriction of 1000 Hz <= Fs <= 384000 Hz, although further hardware-dependent restrictions apply.

The length of frames input to the audio time scaler must be less than or equal to the analysis hop length defined in audioTimeScaler. To minimize buffering, set the samples per frame of the file reader to the analysis hop length. hopLength = numel (aTS.Window) - overlapLength; fileReader = dsp.AudioFileReader ( 'Counting-16-44p1-mono-15secs.wav', ...
