Wwise/Crankcase REV bank with unknown codec by TheAdmiester at 7:11 PM EDT on September 18, 2023
Hi, I have a Wwise audio bank that was extracted from a car in The Crew Motorfest which has the usual BKHD header and appears to contain Crankcase REV (ADM3 header) WEM files.

I can extract the WEMs just fine with bnkextr.exe, and VGMStream thinks it can read them as Apple IMA audio, but what comes out is garbled. If I import as raw in Audacity as VOX ADPCM @ 48000Hz, it's still very noisy but I can just about hear car sounds underneath.

From what I can see from VGMStream's code ADM3 should be a Crankcase version similar to that used in Cyberpunk, and the format of the file I have seems to be the same (chunks of various RPMs, then a acceleration sweep, then more RPM chunks, then a deceleration sweep, then the idle sound), and I can see similar headers to the Cyberpunk files - I'm just stumped getting those sweeps to actually play back.

Sample file here

Side note: in case it's useful for these WEMs - 24 bytes after the end of the GRN1 header you have two floats, these are a granular synth "clock" that you multiply by 120 to get engine RPM, so in the first WEM of this file we have 7.49 (898.8rpm) and 56.47 (6776.4rpm)

Header looks mostly the same but it's now v7, maybe they swapped the codec.

Looks like some ADPCM/IMA, post other samples and the exe (and .dlls related to Crankcase / Wwise if there are some)

Thanks for the response. As far as I'm aware the actual exe is protected so here is a link to a dumped copy.

Wwise/Crankcase seems to be statically linked as there are no dlls that seem to relate to either in the game's folder. Here are two more samples, which I believe are the engine and exhaust sounds for one car.
Sample 1
Sample 2

Fixed those, also ADM3 in bnk now play but can only use the first subsong for technical reasons.

Just grabbed the latest version and it works perfectly, thanks.
