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?

Are you sure about Audition doing something at 32 bit with 16 bit files? With Cool Edit, if I open a 16 bit file, all operations are done in 16 bit. This is preferable. It gives me control of what is done.

I can convert the data to 32 bit after opening, or have the program automatically convert upon opening, but then I no longer have a 16 bit file. It stays 32 bit until explicitly converted to something else.

Are you sure...

Not at all I was just thinking I read that somewhere but I could be completely full of s___. (I haven't been feeling all that well lately so I may not be thinking too clearly.)

I'm hoping that promised documentation from Adobe is coming any day now.
