Audioduct.com is all about delivering basic knowledge of audio to the novice.
This site is not meant to teach you everything you ever needed to know about audio; but it is a great starting point.
If you want to learn some audio basics in easily understandable language, then you are in the right place!
This site is divided into 3 main sections:
Lessons will take you step by step through some basics in a naturally flowing progression. At the bottom of each lesson page you will find a very short quiz that tests your knowledge of what you just read. There are also navigation buttons to take you step-wise through the lessons.
Topics of Interest are short articles on some peripheral topics that are related in some way to audio.
Ear Training will help you begin to develop some auditory skills that you would need as an audio engineer.
