In-game files (extension ASR) (Sniper Elite V2)

I was looking on the Internet for ways to unpack the StreamingSounds.asr file (it stores the sounds of shots, heartbeats, music ...). Found, like, a way, through "offzip", but either I'm crooked, or this method is no longer working. In general, if someone can unpack this file and pull out sound files from there, I will not be in debt ...
