There are many different audio standards and audio types. It is important to legalize your audio levels, especially when you're working with a broadcast network. Why do you need to do this? How do you legalize your audio levels? In this video, learn the importance of legalizing your audio.
- There are many different audio standards and audio types. How do we know what the studio needs and what to deliver? Well in most cases, broadcast houses will have a prepared document that will address most if not all of your questions. Things like what audio levels to use are the ones that are of interest to us in this title. First, let's understand the CALM Act. That is C A L M, the Commercial Advertisement Loudness Mitigation Act requires the U.S. Federal Communications Commission to bar the audio of TV commercials from being broadcast louder than the TV program material they accompany. That's pretty cool. That prevents commercials from being louder than the program. But what that means is that there are audio standards that must be followed if you want to broadcast your program. Most of the time, the audio will need to be between minus 23 and minus 25 LKFS. Go ahead and open Sequence 5.1 while legalize and move your play head towards the beginning. Go ahead and maximize the program panel. You can do that with the grave key and just read what it says. Paid program providers provide a measured average of minus 24 LKFS et cetera, et cetera, et cetera. This is an excerpt of an audio deliverable sheet that I copied just before making this title. I changed some of the words as to not mention any broadcast corporation. Now this says clearly that we have to peak at an average of minus 24 LKFS. So what we need to remember is that most broadcast houses will have these documents. We need to be very clear on what settings to use and we do need to follow all of these guidelines. Getting a program returned because it didn't follow guidelines can be embarrassing. A way to legalize your audio is with a multi-band compressor.
