Wildstar audio format

[Voxx]

Hello!
I tried to export the music files from the new MMO PC game called Wildstar. Seems they use BNK extension to store the music files. I successfully extracted the Music.bnk file from th archive with their own tool (Wildstar Studio) and then extracted the files from the .bnk container with "bnkextr.exe" but I received RIFF files in an unknown format. Tried to convert them with various converters with no success. No tools knows this format yet. The last tool I tried called "ww2ogg" gave me an error message at least: "parse error: RIFF truncated"

I uploaded a sample of the audio files to here:
http://mediafire.com/download/n4n2lcxlfcaf72s/.002.wav

From MediaInfo:

General

File size : 2.72 MiB
Duration : 1mn 24s
Overall bit rate : 271 Kbps

Please take a look and see if you could identify the format / recommend a converter. Thank you in advance!

Tried open with any audio editor? Like goldwave or/and audacity.

There are a few articles on the internet about BNK audio. I can't read them while I'm at work due to restrictions (we can't go to any gaming websites), but just putting something like this:

BNK audio

in a Google search gave me a few articles that seemed promising about working with the audio from the brief summaries I could read. Please don't be too lazy to do a simple internet search.

Try decoding the BNK files with ffmpeg. BTW: not all audio codecs are well-supported in the WAV container.

It is a WAV file, but ffmpeg can't decode it. That's why the publisher uses that particular codec. To make it harder for you to rip off their audio files.

The BNK file itself is not an audio file, it is a container used by many game developer companies to store their data:

I believe this is it or something similar:

With bnkextr.exe I managed to extract this soundbank (.bnk) file already and I received a couple of wav files. The download link on my first post contains one of those WAV files to let you able to inspect the format because I couldn't find any editor / converter program that actually knows this wave format.

FYI --- WAV is a (RIFF-based) container as well.

Besides, http://wiki.multimedia.cx/index.php?title=TwoCC says:

If I were you, and as a last resort, I would send an e-mail to Kostya:
