Thanks for finding that, I checked my Reaper source files and it's using wma and I have the Audiophile with wma/flac
I don't know what the main Biab app is using, it has *.WAV in the path in a frozen SGU so it could also be using wma rather than flac ?

In Reaper you can use https://stash.reaper.fm/v/47910/Change-selected-realtrack-source-file-type.zip this should fix the issue for now.

I used to beta test but now I test on release as there don't seem to be many testing the Plugin.
