Hacking Problems with audio files from Shin Megami Tensei V

[Deleted member 575055]

Hello. Recently, me and a friend decided to dump the audio files (songs, voices, etc.) from Shin Megami Tensei V, to publish and document them on GitHub, and we found some things. There were two folders inside a "Sound" folder: Stream and Stream_en. We extracted and converted everything correctly from the Stream folder, no audio files or cutscenes had problems. But we had problems with the folder Stream_en. From what we heard by listening to some files, Stream_en seems to have japanese and english voices audio files, and apparently some cutscenes. The video cutscenes works well, but all the audio files (voices or cutscenes audio) inside the folder have some background noise that makes listening not good. We extracted these audio files and got .bin (apparently hca or adx files) and tried converting them with ffmpeg to flac or mp3, but that didn't work. Did we do something wrong ? Did we miss something in the extracting or converting process ? I attached an .awb file from that folder in case anyone wanna try to do something with it.
