.pcm is a format type, not a file type as such. All uncompressed audio in Audition is PCM, but if you want to save that, then you have to pick one of the .pcm file types (generally .wav). So if you look in Audition's files list you'll find an entry like this:

and the highlighed line should give you a bit of a clue...

As I said, it's not a file type. If you want to know more about this, look at the libsndfile home page, where you will see a table with various PCM format types down the left hand side, and file systems that can save those formats across the top. You will not find PCM in the top list, because PCM is not a file type; it is a format that can be saved in different configurations. So for instance a wav file could be, for instance, a 32-bit stereo PCM format, or equally well an 8-bit mono one. They would both be PCM files, as would be an .aiff. But PCM cannot be stored without defining the paramaters, and then placing them in a 'container' with a recognised extension. But that extension can't be PCM!

"But that extension can't be PCM!"

 

This is not factual. I have at my disposal several dozen files that are ".pcm" and they are readable in Adobe Audition.

 

This outright proves that .pcm is a file type.

From fileinfo.com:

What is a PCM file?

Uncompressed (raw) digital audio file; a direct representation of the digital sample values (1s and 0s) of an audio recording; stores audio in a format also sometimes used in .WAV and .AIF files.

 

It stands for Pulse Code Modulation. You can call a container anything you like within reason, but that does not make PCM anything other than what it is - a modulation format. If you want, it's perfectly possible to save MP3 files in a PCM container; in Audition libsndfile will interpret it as a PCM format. Oh, and the above information is factual; I'm afraid you have proved nothing. If you want to know more about containers, then look here.
