create pkf files for multichannel wav
Only having a rudimentary knowledge that .PKF files are metadata used for display caching purposes (opening and displaying WAV files more quickly), I was wondering why multichannel WAV files can't have this? I have a multi-track recorder that saves the data as single, multi-channel WAV files. I have noticed that, when opened, no PKF file is generated, and when opening a session, it takes ages to open and display, as the large files have to be re-scanned every time the session is loaded. I have wondered this in regards to loading other file formats as well. Why can't metadata be created to describe the files as well, and not just WAV files?
Kindly note: I'm not looking for hypotheses here. I only desire facts from staffers/engineers or simply to request the feature, if possible.

Hey Matt Stenger,
This is a multi-channel WAV file. And I already did check those boxes and the drives, as you can tell by the fact I noticed PKF files generated for certain WAV files, but not the multi-channel ones. How large of a file can I attach here, or do I need to submit a file a different way for analysis?

Audition does save peak files for uncompressed formats such as WAV and AIFF. This includes Multichannel audio files.
From what you are describing, it appears that you have the peak file generation turned off in the Audition preferences.
You can double check by making sure that there is a check box next to "Preferences>Media & Disk Cache>Save Peak Files..." Be default it is turned on.
If you check that on peak files will be generated for media as it is imported.
If you have that checked on and there are no peak files being generated, then you might be opening files from a disk that is unwritable (that you do not have permissions to write to), or the file needs to be conformed in some way (file is video or compressed audio).
The multitrack recorder you mention might be generating some sort of compressed format. Posting an example will help us determine if this is the case.
