Preface

What is audio?


Audio is "sound" which is detectable to the human ear. Sounds are pressure waves of air that we hear because our ears are designed to be sensitive to these waves.

For humans, hearing is usually detected between the approximate range of 20 Hz and 20 kHz (20,000 Hz). 20 Hz is the lowest pitch (bassiest sound) we can interpret 20 kHz being the highest. It is recognized that as humans get older, the higher range of our hearing perception can often deteriorate.

In a computer environment, audio is often used to describe the sound system that is included with (or can be added to) a computer system, providing the processing and playback of audio files. Audio which is recorded or played back through a computer system is digital audio.
