You should know that posting in a mastering forum. |
First of all, no need for this tone, alright!
So, sure if I save the file as 24 bit *after* the 80db reduction it would destroy the dynamic range. What I meant is that in Audition, it doesn't matter what you start with, you can apply dramatic amplification operations and the internal 32 bit floating point will take care of it for you.
In fact, I just repeated the test and here is what I got (see attachments).
Now back on topic - if you work in Audition, the default saved format is actually 32 bit floating - unless you explicitly tell it to save as 24 bit interger, it won't. So in this case, you are absolutely fine!
Even if you did save as 24 bit - don't sweat over it - I am sure your Normalization operation had absolutely no practical implication about the quality of your audio.
