Requirements & limits

Windows and a separately obtained binkadec.exe that writes a proper WAV header. This proprietary decoder is not bundled. Running the source requires Python 3.9+; the GUI uses tkinter, and packaging uses PyInstaller.
Inputs are matching .ubulk and .uasset or .uexp files, or a complete .binka file. The wrapper locates the UEBA header, rejoins it with the bulk stream and delegates decoding. Other cooked codecs and inline-only assets are outside the documented scope.
For paired assets, sample-rate and channel mismatches or a duration difference above 2% become warnings. They do not fail the CLI exit code, and --quiet suppresses them. Direct .binka inputs have no original-asset metadata comparison; header checks cover header information, while audio fidelity remains unverified.
MIT covers this repository code, not binkadec or game assets. The README credits FModel, BinkadecWithWavHeader and ue2wav prior art.
