What are the features of audio?

There are, in general, two types of audio features: the physical features and the perceptual features. Physical features refer to mathematical measurements computed directly from the sound wave, such as the energy function, the spectrum, the cepstral coefficients, the fundamental frequency, and so on.

What is spectral bandwidth audio?

Spectral Bandwidth

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.

What is acoustic feature extraction?

The purpose of feature extraction is to illustrate a speech signal by a predetermined number of components of the signal. This is because all the information in the acoustic signal is too cumbersome to deal with, and some of the information is irrelevant in the identification task [7, 8].
