How can I understand in which time position in STFT function output am I?
For example, if I have 3987 time frame in the output of STFT, my window length is 625 (hamming), my hop size is 125 and the length of signal is 2 second.
How can I estimate for example the first 5 milisecond or a window of 10 milisecond in the ouput of STFT? I know that the the number of time frames are calculated by
coln = 1+fix((xlen-wlen)/h);
But how is the equation in my situation?
- Can I say that each time frame has a length of hop size?
