Audio signals include speech but also music and all types of sounds. On a compact disc, the audio signal is limited to a maximum frequency of 20 kHz. It is sampled at 44.1 kHz and each sample is coded on 16 bits. The bit rate of the resulting PCM code is 706 kb/s.

The audio signal is an analog signal that is electrically correct for an audio signal. The frequency range normally heard by humans is between 20 and 20,000 Hz, approximately equivalent, almost at 10 octaves. Audio Formats A digital audio file is a sound or sound sequence that has been converted into a digital format for storage on a computer.

We are plotting frequencies ranging from 0 to 8kHz because our signal was sampled at 16k sampling rate and according to the Nyquist sampling theorem, it should only posses frequencies ≤ 8000Hz (16000/2). Strong frequencies are ranging from 0 to 1kHz only because this audio clip was human speech.

Audio signal can be any frequency that contains audio information. So, let’s take AM radio. Those signals are modulated with audio information by changing the RF signal’s amplitude. Audio frequencies are the actual base band information. Those frequencies for humans range from 20 Hz through 20,000 Hz, sent via acoustic waves.
