Analog connections are the foundation of a digital studio. Matt compares microphone, instrument, and speaker cables with 1/4" TS and TRS connectors, XLR connectors, and other plugs and jacks. Headphone connectors and other 1/8" plugs are also TRS connectors, where the two signals share a common ground connection.

- All digital audio involves the analog domain as well.…Because of this it's important to be familiar…with analog connections.…Let's talk about physical connectors and cables,…the types of signals passed along those cables,…and some rules of thumb about which connections…are used and when.…There are nearly infinite combinations of these…so we'll only go through a few common examples.…As I discussed in the video about signal flow,…there are three main categories…of the strength or level…of the electrical analog signal.…
Mic level, line level, and speaker level.…Mic level is the weakest of the three.…This is usually somewhere around…a few thousandths of a volt.…Very low voltage.…It can't shock you.…It's less powerful than even a small…watch battery.…For processing and mixing,…the weak mic level signal…needs a microphone preamplifier,…or mic preamp, to boost it up to line-level.…Line-level is still low voltage…and not dangerous but it's a good…deal stronger than mic level.…
It's usually a little less than one volt.…To play through a loudspeaker though,…
The course starts with explanations of what sound really is and how we hear it, including discussions on frequency, amplitude, phase, and psychoacoustics. Matt explores analog audio signal path, explaining connections, gain staging, and metering. Next, he brings the audio signal into the digital domain, discussing analog to digital conversion, digital gain staging, file formats and compression, and dither.
Then the course digs into digital audio workstations (DAWs), explaining the concepts and misconceptions involved in digital recording systems. Matt describes how memory, CPU speed, and storage affect your DAW's performance, as well as how to manage computer resources and understand the plethora of file formats associated with digital recording. He follows with an overview of MIDI: how to generate, store, process, and communicate MIDI data. He wraps up with the audio processors that are often used for mixing in a DAW—including EQ, compressors, reverb, delay, and many others.
