My question is, how does voice tracking work?
Jimme, I get the idea you have little or no technical vision of how Voice Tracking works. Do you know how to make audio recordings on your computer and then play them back? If not, find a Nerd that does and let them demonstrate for you the marvels and mysteries of .wav files and .mp3 files.
I suspect a lot of people use two terms interchangeably but to me the two terms have slightly different meanings. The first one is AUTOMATION. The programming you hear on any radio station today has a high probability of originating in an AUTOMATION MACHINE. The early versions (starting somewhere around the late 1950s) used tape recorders with large, large reels of music. Various devices were used to play-back commercials, station breaks, etc. There were mechanical timers that looked like they had been born in a washing machine factory. You could set a timer so that the promo, station ID or whatever was on the device tied to that timer held up it's hand and told the music tape (once every 15 minutes) "I need to run when you get to the end of the current track... probably a music track." Another timer might be set to hold up it's hand every 5 minutes and and say to the music tape: "I need to run when you get to the end of the current track,."
The first automation machine I ever saw had a Seeburg jukebox "guts" that played 45 RPM records for music content and had one big spool of tape where every announcement, commercial, PSA or whatever was on that tape in the order it was to play back. No last minute program changes with that thing. (Gates Nightwatch).
Today the whole process lives inside a computer. (Multiple computers can be networked together.) The washing machine timers are gone. Programmers create machine logic that can consider anything you want to use in deciding WHEN a give audio file will play. I guess someone somewhere has included logic to consider the phase of the moon in decided what to do next. There must be 15 or so vendors selling competing, highly sophisticated software to make decisions and make them happen the way a live person would have years ago.
Some specialty programming, some types of music programming just grind out. Small markets in particular. Play the music. Play the commercial. Repeat as necessary. But in major competitive markets where they want to capture certain aspects of the concept of a host or a DJ, VOICE TRACKING takes place. A person of talent sits down somewhere, gathers his/her show prep, and records customized short voice segments that will follow a given music recording. If a station plans to do this type of programming, they will look at all the competing automation machines available and select one that has all the capabilities they want for their style of programming. And the software vendor will include a program that can be on another computer in the next room, in the talent's apartment across town, or in a location seven states away, and as the host/dj/personality records all the little drop-in tid-bits of voice, they are give file names, inaudible beeps and tones, so that the VOICE TRACK recordings can be identified by the master automation machine and played back BY THE COMPUTER in such a way that it comes out sounding like the person is right there and is live.... if the PERSON has the right talent to pull it off.
If you want to understand it all better, there are some automation software packages that can be downloaded for free, or for a limited time trial period. You can put one on your computer, load in 10 or 15 music recordings, a dozen fake commercials, create something that sounds like a station promo, and you can have your home computer sounding like a little radio station.
Radio stations do not appear to be as "visitor friendly" as they once were, but if you live in a smaller market, you may find that your local radio station would let you come in and see what they use, allow you to sit in the studio while someone prepares program content and then when you get home you can HEAR what you saw IN THE MAKING.
