Description: Learn the nature and science of musical sound, audio, and perception in this course from audio engineer Joe Albano. This is the first course in our “Audio Concepts” series, covering the fundamentals of sound and audio. It covers all the concepts and terminology audio professionals need to know as they delve into everyday studio work. This includes the physical properties of sound waves: amplitude, frequency, and waveform, which are elements of sound that can be creatively manipulated during recording and mixing.
What is sound and audio? How can we measure it? Why do we perceive it the way we do? Learn the nature and science of musical sound, audio and perception in this pro-level audio course by sound engineer, Joe Albano.
This first course in our Audio Concepts series, is all about the basics of sound and audio. It touches on all the concepts and terminology that audio pros need to know as they dive into typical, everyday studio activities. This includes the physical properties of sound waves: Amplitude, Frequency and Waveshape which are the elements of sound that are creatively manipulated in recording and mixing.
It also covers sound measurements and demystifies the terminology and acronyms you see in plug-in graphs and mixers, like Hz, kHz, dB and dBfs, that help us find just the right settings for particular tasks. There’s even a section on how our human hearing works. This is the basis for understanding the psychoacoustic perceptions that underpin many classic studio techniques and effects. Then there’s a very brief but serious look at hearing protection which is a very important but often overlooked topic.
