About this document
Audio Feature Extraction Techniques by Rodrigo Sánchez Mariño is a document available to read on EtoBox.
This document summarizes an audio processing and analysis lesson that discusses: 1) Representing audio signals in both the time and frequency domains, including using the discrete Fourier transform (DFT) and fast Fourier transform (FFT) to obtain a frequency-domain representation. 2) Computing spectrograms, which provide a two-dimensional time-frequency representation of audio by applying short-time FFTs over windows of the signal. 3) Code examples for calculating the FFT of a simple test signal, compu
