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 ...

The spectrogram application is a simple program that computes the spectrograms of a set of audio files. It is designed to be fast and easy to use. It relies on the spectrogram module of the FFFT ...

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 ...
