Following the conversation on the other forum, one user has noticed that these files all start with 0x 09 00 00 03, this string also appears in normal wma files at the beginning of the data area. Another user first identified them as wma according to a 'format tag' acquired somewhere, possibly in the container file.
Of course that doesn't guarantee the data after that string can be assumed to be a regular wma file but it would seem that the headers have been chopped off at the very least... given that the game has a mix of pcm wavs and this 'wma' format and given that the files are bundled in what appears to be standard 'Xbox wavebanks' (.xwb) and given the game is only available for PC and Xbox 360 and given that the textures have already been identified as standard DirectX textures minus the header, then there is probably a strong possibility that it is indeed something pretty standard.
If Omo hadn't beaten me to it I would have requested someone take a look into it as well :)
you means its 96kbps? The guys that converted a song to mp3 was 96kbps... If they were 96khz they'd be really large right? :-) How is the playback of the D0A4 WMA so far? Curious :P
Well they say it is - by the time I've converted it to wav it's standard 44khz stereo pcm and I don't know how to play the .xwm files if that's even possible.
