Digital Audio (1 of 3): Sound Basics, Audio Recording and Sound Effects

The next unit is "Digital Audio." Before you start working on the assignments, you will first explore the basic science of sound and audio recording.

The platform used for the videos is EdPuzzle. You can download the EdPuzzle app if you are using a smartphone (Android and iOS). CLICK HERE for more information.

A sound wave can be represented as a waveform which graphically describes the shape of the wave.
Sound waves can be either Non-Periodic or Periodic.

Non-Periodic consists of a single wavefront that quickly dies out (for example, a hand clap).
Periodic sound waves are created by the vibration of an object (for example, a guitar string or tuning fork)
