Each horizontal slice of the spectrogram therefore represents ~94 Hz of bandwidth. You can increase resolution by using a larger FFT size (e.g. 1024, 2048), which allows for finer frequency detail ...

Create a spectrogram from a audio signal. n_mels (int, optional): Number of mel filterbanks. (Default: ``128``) sample_rate (int, optional): Sample rate of audio signal. (Default: ``16000``) f_min ...

Abstract: The concept of the two-dimensional spectro-temporal modulation filtering of the auditory model is implemented for the FFT spectrogram. It analyzes the spectrogram in terms of the temporal ...
