Interpolation of Clipping and Bit-Rate Questions., Adobe Audition Help for a Noob. Options

[Engelsstaub]

I've been testing out the trial of Adobe Audition and have noticed that it is a bit more detailed in analyzing and manipulating peaks and "clips" than Audacity. My immediate example is a needle-drop of Krisiun's "The Great Execution." (One track--1st illustration below.) The CD and iTunes Matched AAC files are a complete mess in that most of the entire recording is clipped or squashed or whatever. (Same track--second illustration below.) (Krisiun is a Brazilian "death metal" band, so there's quite a bit of sound anyway!)

LP Rip @ 16/44.1


iTunes Matched AAC file



If you look at the needledrop in the first illustration you'll notice five places (bottom/right channel) where the sound clipped for a small fraction of a second. I was thinking of zooming in and doing a simple "auto heal" on those as I'm very pleased with the sound of this album when burned to Redbook CD-R. You'll also notice that, if you look at the bottom-right of both illustrations, that Audition is working at 16-bit for the vinyl rip (recorded at 16/44) and 32-bit float for the iTunes AAC file.

Some questions: will working on those few clipped samples and exporting the results at the same bit-rate reduce the quality of the original recording? Why does Audition indicate that it is working at 32-bit float for a 16/44 AAC file while it remains at 16-bit for the FLAC?

The documentation is awkward.
What is "best audio quality"? The quality Audition assigns to everything it does or what it uses when the user in some manner requests "best" or what it uses when the input is 32 bit?
What did the writer mean by "transforms"? by "in 32 bit"? by "saves"? Converts the entire input to 32 bit and only reconverts to the original bit depth when the file is put away? Converts that part of the data it uses for any particular operation to 32 bit and reconverts to the original bit depth as it "saves" the result? Nothing there is specific enough to assure one and only one reasonable interpretation: poor documentation.
