An essential concept in capturing audio is to understand signal flow. It forms the foundation of almost everything else in audio production, and particularly in capturing sound on location. In this movie, professor Jeff Jacoby explains the how and why of signal flow, and gets you started on the road to a clear understanding of your audio flow.
In this movie, we'll look at a concept you absolutely need…to understand if you're doing audio on location…or in the studio, for that matter.…It's called, "signal flow."…Signal flow, simply put, is the path…of the audio signal from it's source…to its destination.…Think of a river.…Water, like sound, flows from one place to another.…You can even split it off into tributaries…and send it several places at once.…And we are in fact doing that right now.…Alyssa, our recordist, is capturing the sound…on the recorder, but she's also listening to it…on headphones.…
This is the one concept you need to understand,…and when you do understand it,…less than three minutes from now,…you'll have come a long way…toward understanding all audio systems.…It's not that complicated.…The source of the sound you're hearing right now…is my voice coming out of my mouth.…I know that's obvious, but bear with me on this.…The question is, where does my voice go next?…Into a microphone, right here, a lavalier.…Then it goes down a cable under my shirt…
