Masking Audio STFT Matlab - Stack Overflow
https://stackoverflow.com/questions/70556183/masking-audio-stft-matlab
I want to implantation a masking time-frequency audio. In first, I am using the function : S=spectrogram(x,window,noverlap,nfft) on Matlab, to extract the STFT of the noise+target signal (from WAV file). After that, I am forcing on some coefficients of the STFT(S variable) to be zero with decision of some threshold.
Manual Implementation of STFT of an audio signal.

My steps can be mentioned as follows :- a) I take samples out of the file in chunks of 1000 samples each and process them one by one. b) For each chunk , I find its STFT . c) I plot the magnitute squared of the STFT and hold that plot. d) I repeat the whole process again and again till all the samples of the audio file have been used.
Short-time Fourier transform - MATLAB stft

STFT of Multichannel Signals Generate a three-channel signal consisting of three different chirps sampled at 1 kHz for one second. The first channel consists of a concave quadratic chirp with instantaneous frequency 100 Hz at t = 0 and crosses 300 Hz at t = 1 second. It has an initial phase equal to 45 degrees.

I am not too familiar with audio processing, but even if two signals have identical power spectrums, minor changes in the complex phase of the FFT can result in dramatically different signals in the time domain. 2) The syntax seems a bit different from what I am used to in Matlab, but the answer is YES.
