Many creatives find spatial positioning in audio daunting—but it doesn't need to be. This video explains the way audio recording and output with multiple channels can create the experience of spatial locations for sound sources, while breaking down the technology to its simplest components. Once you understand the way audio channels combine, you can understand the use of any number of channels for even the most complex of sound mixes.
- [Instructor] Our brains do a lot of calculating for us…before information reaches our consciousness.…For example, you've probably had the experience…of being in a conversation at a party…and suddenly hearing your name spoken from across the room.…Somehow, in amongst the noise of everyone speaking,…you managed to hear just your name.…This isn't actually what happened.…In all likelihood, your brain was listening…to everything in the room all at once…and filtering out noise that didn't seem important.…But someone saying your name is important,…and so that part came through.…
The filter was removed on purpose…without your conscious mind knowing anything about it.…This is one of the many so-called autonomic processes…in your body,…like breathing when you're not thinking about it.…But of course, now you are.…When we hear a sound, we quickly build an image or a model…of the source of the sound in our minds.…This is possible partly…because there's so much information included with the sound,…like the location relative to us,…
Get ready to remove the mystery behind terms you've encountered. If you work in a creative profession, this can enhance your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo should be supplied in vector or bitmap form, and more.
