Area 51 (Xbox) Music files by Anterag at 5:31 PM EDT on April 21, 2019
Hello everyone. I need some help to convert the music files of Area 51 (Xbox version). First, I extracted the content of the MUSIC.000 archive which contains the music package files with a BMS script (http://aluigi.org/bms/area51.bms) The music files are inside the *.AUDIOPKG archives. The sample below comes from this archive: https://mega.nz/#!L5Ei1aoa!8EUkE-l6y_-VC1vSxTRGQP1OJzZPh3A6fQOeSfAT6d0 To extract them, I used AlphaTwentyThree's script https://mega.nz/#!vxdgmCZK!9YG3xc7HQ_OYehgDD72jE6ggk0UKJO87jSr8Gj63Nr8 There's no issue until this point because the problem is to rebuild a correct header in order to play the music files with vgmstream. Apparently, the music uses the Xbox 4-bit IMA ADPCM codec, at 32000Hz, stereo, with a blocksize of 0x8000.
Here's my TXTH script which doesn't work (the music can clearly be heard without any static at the beginning, then garbled noise, then music, etc.)
