I had to do a school project to do a time frequency analysis on audio and chirp signal. This project allows us (if you finish it, and i finished it) to do a Time-Frequency Analysis for evolutionary signals.
/!\ All my comments are not necessarily in english /!\
For this project and all projects, it was obliged to create a demo version (with a chirp signal) and a project version (with an audio file).
To do the analysis, we needed to create an hamming window and shift this window.
It's important to make a matrix filled by the multiplication of hamming vector and our initial signal. Finally, this matrix can be dislayed with the imagesc command.
It was important for the project version to let the user to fill intervals to reduce the initial signal.
The initial signal is received by using my function get_audio_signal and the function audioread.
Finally, the user had to be able to fill the length of hamming window and the length of the increment.
