About this document

Audio Sampling and Frequency Analysis by Azfar_Nazim_6025 is a document available to read on EtoBox.

This document contains code to record audio using the wavrecord function at different sampling frequencies, and then play it back using wavplay at different sampling frequencies. It records audio at 11 kHz, 8 kHz, 16 kHz, and 32 kHz, and plays it back at 8 kHz, 16 kHz, and 32 kHz. It also takes the FFT of a recorded voice signal to analyze its frequency content, plotting it from 0-16 kHz and showing that most of the voice signal exists between 0-3.4 kHz.
