Phần 1: Giới thiệu Âm Thanh.
Introduction to Audio
This beginner-level tutorial covers the basics of audio production. It is suitable for anyone wanting to learn more about working with sound, in either amateur or professional situations. The tutorial is five pages and takes about 20 minutes to complete.
What is “Audio”?
Audio means “of sound” or “of the reproduction of sound”. Specifically, it refers to the range of frequencies detectable by the human ear — approximately 20Hz to 20kHz. It’s not a bad idea to memorise those numbers — 20Hz is the lowest-pitched (bassiest) sound we can hear, 20kHz is the highest pitch we can hear.
Audio work involves the production, recording, manipulation and reproduction of sound waves. To understand audio you must have a grasp of two things:
- Sound Waves: What they are, how they are produced and how we hear them.
- Sound Equipment: What the different components are, what they do, how to choose the correct equipment and use it properly.
Fortunately it’s not particularly difficult. Audio theory is simpler than video theory and once you understand the basic path from the sound source through the sound equipment to the ear, it all starts to make sense.
Technical note: In physics, sound is a form of energy known as acoustical energy.
