One of the most common complaints from “project studio artists” is that their mixes don’t 

sound loud enough. You burn a CD of your mix, put in your CD changer, and it just can’t 

compete in rotation with the commercial CDs you have. You turn it up, and it just overloads. 

What’s going on here? 
 

The secret is a loudness maximizer. And of course, Ozone provides you with one Like all 

Ozone modules, it uses 64-bit processing and proprietary algorithms that can boost your 
overall level without overloading, and still sound natural.  

 

A loudness maximizer can do more than just push more volume into the signal. In subtle 
amounts, it can add fullness and depth to the music. Unfortunately, commercial CDs have 

recently been focused more on the loudness than the fullness, and the overall level of CDs in 

recent years has really reached an extreme. If you feel the need to compete on this front, we 

do understand, and with Ozone you have the tool to sound as “hot” (level-wise, at least) as 
anything in rotation. We just wanted to mention that you can use the Loudness Maximizer in 

subtle amounts to add fullness and body to the music, in addition to just putting the Ozone 

pedal to the metal and making your CD louder than Everclear’s latest CD (which you also have 
the ability to do with Ozone) 

 

Most sound editors have a Normalize function. What this does is that it looks at your entire 

mix, finds the highest peak, and adjusts the level of the entire mix so that the highest peak in 

the mix is at 0 dB (the verge of clipping) and the rest of the music is adjusted in level by the 
same amount. But all that does is makes the single highest peak on the verge of clipping. In 

fact, you can cut out or limit short peaks and in general you won’t even hear the difference. 

 

 

 

 

 

 

 

 

 

 

 

 

 

Bonus Tip: Ozone does have an "autonormalize" function which 

allows you to play your mix and automatically set the input 
and/or output gain so the mix peaks at 0 dB (or whatever peak 

you want). You can access this feature from the level meter 

option menu (right click on the level meters) then click the 

"Auto-Normalize" button. 
 

 

 
 

 

 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

So the principle behind a loudness maximizer is that you can limit the peaks above a certain 
point (the Threshold parameter) and then bring up the rest of the mix to a maximum dB. The 

bulk of the mix can be brought up since the peaks are cut down, so nothing overloads 0 dB. 

 
The trick is developing an algorithm that limits the peaks without creating artifacts in the 

sound. The Loudness Maximizer in Ozone has strong but natural algorithms that can let you 

bring down the peaks and bring up the heart of the mix for a fuller sound, or in extreme cases 
just a louder master.
