As I expected, the file has BNK files inside in addition to usual WAV files. And that's why all extractors fail with it.

I can't download the file to the end yet, it's slow and always fails in the middle.

can you maybe give us a sample?

I have a feeling that none of these will be able to decode all sounds. You can have most of 17000 files working with Wwise_PCK_Decoding, but still will be missing some 1000's of them.

What's the total size of sounds_sfx.pck ?

Just use another one of those 3.

What did you use to extract them?

In short: you extracted these files wrong.

I think you don't understand how wwise banks work. From these 5 files, 4 files are proper 6-ch music files, all converted ok with OLD codebooks. And the first file is probably the result of your attempt to extract the prefetch data from the sound bank. This contains about 300 prefetch blocks, combin...

if you need it, i can convert these 63 banks for you. Is that all of the banks?

I don't know what is MFaudio, but these banks contain the most usual PS 4-bit ADPCM sounds, which are convertable with vgmtoolbox. I think there must be some tutorials on that, because 100's of games use this.

Can you post a sample of such file?

I found that is because of a problem with BMS script. It will be corrected soon.

So was it helpful? Do you need any more info on this game or engine format?

Tell us some more about them.

stereo = 2 channels

you can play genh with VGMStream (or convert to wav)

Choose GENH, then RAW PCM and the parameters I mentioned. Also "no loops", then you'll get the file playable with VGMStream
