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 the 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. The tool called "ww2ogg" gives me the error message: "parse error: RIFF truncated" I uploaded one of the audio files to here: mediafire.com/download/n4n2lcxlfcaf72s/.002.wav From MediaInfo: General Complete name : D:\GAMES\UJ\2\.002.wav Format : Wave File size : 2.72 MiB Duration : 1mn 24s Overall bit rate : 271 Kbps Audio Format : In Development Codec ID : FFFF Duration : 1mn 24s Bit rate : 271 Kbps Channel count : 2 channels Sampling rate : 48.0 KHz Stream size : 2.72 MiB (100%) Please take a look and see if you could identify the format / recommend a converter. Thank you in advance!
