![]() ![]() This raises the loudness to -20db and lops off a few peaks in the process. I then get into the Waves L2 Maximizer (or Sony WaveHammer) and set the threshold for -7.4db and let it do it's thing. Let's say it's -27.4db with a few peaks to -2db, I subtract 20 from that and end up with 7.4. First, I go to "Process" > "Normalize" and scan the levels, noting the RMS level. Typically, I set all my projects to an RMS "average" loudness of -20db using Sound Forge. But like I said, peak levels are virtually meaningless (well, as long as they don't exceed 0db.) If you're watching a movie on TV and it has some relatively quiet dialog and then a commercial comes on, the commercial sounds louder because it has been heavily compressed in order to raise its average level (and get your attention.) The fact of the matter is that the movie and the commercial probably had the same peak level, it just that the commercial has a much higher average level.Īudio compression and limiting is an art form and it takes a lot of experience to do it "correctly." There are no hard and fast rules to determine the appropriate average level, you'll just have to play it by ear. The "normalize" function in Vegas is useless because it only makes adjustments based on peak levels and that's not they way we hear things. The human ear doesn't determine loudness by the peak level, it determines it by the average (or RMS) level. Unfortunately, peak levels are meaningless when it comes to determining how "loud" your final product is. The "Normalize" function in a lot of programs, including Vegas and probably Real Player, only adjusts the peak audio level to a specific value.
