New file location on In-game Sounds??

Hello! I use to mod a lot of the LoL in-game sounds with customs sounds like: Custom champion voices, Custom announcers, and I was just curious if it is still possible to mod them. I use to mod the file "VOBank_en_US" with a fsb extract and simply replace the the sounds I wanted with new ones and the compile them and bam! I was curious if this is still possible and if there was a new file that I could mod just so I could hear some of my custom sounds.

Hope someone could shed some light so I can share all my custom announcer voices with you guys!
