Ace Combat 7 Wwise IMA ADPCM(?) audio files

Post by Bitter_Tango »

Grettings! Since there's no way to extract data from the *.pak files yet (they are encrypted and require a key to be unpacked), I did a memory dump of the game and was able to extract a lot of *.wav files using AlphaTwentyThree's WAV scanner script.

Since the game uses Wwise as its audio engine I figured the files would work with ww2ogg, but they are actually IMA ADPCM files. I tried to use HCS's ima_rejigger5 tool, but when the files are converted, the output files' duration are ~1-3 seconds long, although they are still audible.

Here are some samples varying in size for if somenone wants to take a look. Thank you in advance for any help!

Do you plan to submit them to the Sounds Resource? If so, make sure they are playable with proper names,

Not interested in doing that, sorry. My intention was to extract the music since there are some tracks that are not included in the game's sound player, althought if a working tool or script is provided, someone else can upload the sounds to that place.
