Frequency and amplitude: Foundations of Digital Audio

Matt shares that frequency and amplitude are two of the fundamental aspects of sound. Frequency, measured in Hertz (Hz), refers to how often the waveform moves up and down, and amplitude, referred to in decibels (dB), means how far it moves up and down. He explains that decibels are not units, but a way of expressing a ratio; however, they can be used as units of measurement if compared to a reference point like SPL (sound pressure level).
