From the course: Digital Audio Foundations
Welcome
- Hi, I'm Matt Mayfield, and welcome to foundations of digital audio. Digital audio is the basis for practically every sound recording in the 21st century. This course was designed to introduce you to the concepts that underlie audio engineering, music production, and sound recording of any kind. First, I'll give you an overview of the essential concepts of what sound is, examine the way our ears hear sound, and break down the three domains of audio: acoustic, analog, and digital. Then, we'll look closely at the analog signal path which all digital audio is built upon, including, analog connections, gain stages and metering, and I'll show you the differences between mic-level, line-level and speaker-level. Next, I'll demonstrate how the digital domain is built on top of the analog domain, and explore digital concepts like the sampling process, dither, and common file formats. (electronic music) After that, I'll define the five main types of digital audio workstation, give you an overview of effects plug-ins and virtual instruments, and offer some rules of thumb to help you determine exactly what computer hardware you need and what you don't. Then, you'll see what MIDI is. How it compares to digital audio, the way that it captures the performance, but not the sound, and how MIDI can give you incredible creative flexibility. Finally, we'll examine how digital audio can be processed and mixed using tools like automation, equalization, compression and more. By understanding the principles digital audio is based on, you'll be well prepared to accomplish anything you set your mind to in terms of recorded sound. So if you're ready to go, let's dive in to Foundations of Digital Audio.
