Hello everyone,

I have obtained spectrogram image from an audio using following code. Need to find the signal from the spectrogram image. Since the process is two sided, it should be possible but I am not sure how can I do that. Link for the guide: https://www.mathworks.com/help/signal/ref/stftmag2sig.html

clear all
close all
clc
[y,Fs]=audioread('audio2.wav');
sound(y,Fs) %To hear the sound
ty = (0:length(y)-1)/Fs;
wind = hamming(128);
olen = 64;
nfft = 1024;
stft(y,Fs,'Window',wind,'OverlapLength',olen,'FFTLength',nfft);
s=stft(y,Fs,'Window',wind,'OverlapLength',olen,'FFTLength',nfft);
