WebA spectrogram is a two-dimensional representation of the square of the STFT X(m,k) X ( m, k), and can give us important visual insight into which parts of a piece of audio sound like a buzz, a hum, a hiss, a click, or a pop, or if there are any gaps. The Mel Scale WebSep 19, 2024 · There are three types of chromagrams: Waveform chromagram – it is basically a chromagram that is computed from the power spectrogram of the audio files. It classifies the waveform of the sound in different pitch classes. Constant-Q chromagram – it is a chromagram of constant-Q transform signal.
