File Has Large Size But No Audio

Last night I recorded and edited an audio file in Adobe Audition and RX8, I made sure to save it, as that was also needed to port it over into the RX software, after that, I properly shut down my computer only to find today that I can't play the file back and that it also does not automatically get recovered using Audition as it has many times before. I went looking for the original files, but they seem to have disappeared.

I did not change anything or delete them and I made sure that the file would be saved to a directory that I recall.

As of now, the file reports to have a size of 435 MB, but does not play back using any software. The peak file is also available.

TLDR:

i have a 400mb audio file i've recorded and saved from audition. whenever i try to preview it in any software, nothing seems to play. is this file corrupt, and if so is there any way i can salvage it?
