The segments were ex-tracted manually and labeled by experts as containing vibrato or not. All opera segments are sung with vibrato while the percentage of vi-brato segments is approximately 2/3 for pop and 3/4 for jazz. The WebSTFT is a well-known technique in signal processing to analyze non-stationary signals. STFT is segmenting the signal into narrow time intervals and takes the Fourier transform of each segment. In Dewesoft’s FFT setup you can set FFT’s resolution, Window, and Overlap and for better understanding what that means, let’s look at the picture below.
