Rayman Legends PC Audio Container

[!!!!!]

The audio in Rayman Legends on PC uses a PCM & ADPCM container unknown to me. No RIFF header for either however playing the PCM files raw works with clipping in the intro. (Obviously the header) ADPCM though doesn't work even creating a Microsoft ADPCM GENH file.

PCM:


ADPCM:

Have you tried all XORs? You can find the script in my big topic. Cut the header first of course. If you have found out the XOR, just use the same script to process the whole file (explanation inside).

I'm not sure I understand, I've tried the script though I don't think it'll be useful in my hands. I have no idea what to do with it.

Here's a quick rar with 2 audio files, one pcm and adpcm if anyone wants to try their hand.

No XOR needed, PCM files are ok.
Need more ADPCM samples.

Here's 5 more ADPCM samples

Ok, found the time to write the script. Had to implement the generic header first.
Try if this works:

script

I've tried the script and a few PCM files with different headers wont work with it and only outputs the header made by the script. I've also included a adpcm file that distorts after the audio track plays.

EDIT: Added an unworking adpcm CPK.

Corrected the script for PCM files, also corrected the sample calculation for the GENH header and some variable offsets.

However:
The problem with the ADPCM file is that it's MS ADPCM mono, which isn't supported by GENH nor vgmstream. I'm quite at a loss here... If anyone can help I'd be thankful!

Thanks for the quick update, Alpha23. Is it possible for the single channel be copied as the second channel and then made as a pseudo 2ch mono ADPCM GENH temporarily until single channel GENH is supported?

[AlphaTwentyThree]

I'll ask snakemeat first.
Apart from that: I'm not even sure if ms_adpcm even supports mono. And I'm not sure if it's possible to create pseudo-stereo files, but we'll see.

Alpha23 do you have to use GENH headers on the ADPCM files because they are actually Microsoft WAV ADPCM files which if headers were applied, could solve the mono issue.

Well, if somebody could tell me how to construct a valid msadpcm header...

[Savage]

Is possible make a reverse way? convert wav to wav.cpk?

[lonrot]

AlphaTwentyThree please update the script to include sound effects as well!

I managed to extract most music, however with smaller sound effects the conversion returns this useless "filename.wav.ckd.genh" format, and renaming it does nothing.

Here are some original wav.ckd files that are not converting properly:

Thank you!

[AlphaTwentyThree]

As I said, I don't know how to construct a working MSADPCM mono header. The genh header is correct but for some reason vgmstream doesn't play the files.
As of now there's nothing I can do to solve the problem I'm afraid.
