[PS4] Dissidia Final Fantasy NT (.wbh/.wbd)

[DeathChaos]

So I recently dug out a dump for this game hoping to be able to dump the audio clips, but sadly they're in a file format I've never seen before, and research has yielded very little results. 

There was another game that used a similar format, Fatal Frame, but the quickbms script posted for that game did not work.

It seems the audio clips are grouped together in a .sed container file (might be a common format among newer Koei Tecmo games like the Switch versions of Hyrule/Fire Emblem Warriors?)

Here is a sample file for anyone who is interested in poking around;

Any help on this would be greatly appreciated.

Edit: Turns out using a bms script made for Fatal Frame (and changing the endianess from Big to Little) successfully unpacked the sed files, however this leaves me with a wbh and a wbd file, so we are back to where we started, except now I don't know how to open wbh/wbd files as opposed to .sed

Edit 2: Seems that the bms script doesn't quite unpack the .sed files correctly, but there ARE wbd and wbh files in here, wbh seems to have about 4 sections?
I think they might be headerless at9 files (standard PS4 sound files), with the info being stored in wbh, probably block size and such, any help here would be appeciated.

Sample wbd with the correct wbh files;
