headerless ADPCM

Post by AlphaTwentyThree » Sat Aug 24, 2013 12:10 pm

Hi there!

I have some headerless ADPCM files and I'm really struggeling to get them to play. Tried different offsets and codecs with GENH but to no avail. Does anyone have a clue which properties these files have?

As far as I can see, bytes 4-8 give the length of the whole file (I guess you already know that, though) and until offset 46544, they are identical (except for the 4 length-bytes).

This is the point where the contents change:

Code: Select all

EIDOS_IN
46528	99 01 22 BA 5C C0 00 40 00 00 00 00 00 00 00 00
46544	7F F7 7F F7 61 8D 84 1C 92 28 AA 52 BB 85 2A C1

INTROSEQ
46528	99 01 22 BA 5C C0 00 40 00 00 00 00 00 00 00 00
46544	77 75 97 9C 30 12 00 A8 FD BB BD 10 73 57 CC BD
Could you please check if you have any files of that format which have different contents before 46544?

I've imported them into Audacity as raw, VOX ADPCM files and although it was not perfect, I heard few sounds there. Like walking, thunders, shooting, cat, etc.
I tried sample rate 44.1kHz, but it was bit fast, but 32 kHz sounds better.

My try

Yes, the files start out the same (shouldn't matter though). They are audio containers from Hitman 2 for Xbox. The TOC is in *.WHD files, but they don't seem to contain information about the interleave or codec.
I've also tried the raw import of Audacity but the problem is that it doesn't support raw import for other ADPCM codecs. I've searched high and low but didn't find any program that has that feature. So all you can do is try out different settings of GENH. Strangely I didn't encounter a single setting that produced anything besides static noise. Does anybody have an idea what's the closest stereo relative to VOX ADPCM?

LOL, this ist simply XBOX ADPCM! How the hell didn't I recognize this...
Will write an extractor for the wav/whd pairs later. Seems like this is the same engine like Kane & Lynch or Condemned, so the script should also apply to these games.

Glacier engine - WHD/WAV pairs

Games like the Hitman series, Freedom Fighters or Kane & Lynch. You will need to put all whd/wav pairs as well as the streams.wav (if available) into the same folder.
Not all tested, though. So if you have problems with any of the Glacier games, post here.

Code: Select all

# extracts the WHD/WAV pairs from the Glacier engine
# needs the streams.wav in the same folder as the whd/wav pair(s)

Made some more changes - the script now supports the extraction of the streams.wav-internals too (dialogue and music). :D
The streams.wav needs to be located in the same folder as the *.whd/*.wav pair(s).

KL2 doesn't have a streams.wav file, do you still have the older script anywhere?

It should also work without the streams.wav I think.
Will update the script with PS2 ADPCM soon.

Doesn't seem to. errors out with a no such file or directory on streams.wav

Added support for games that use IMA ADPCM, e.g. the PS2 version of Hitman 2! :)

Really great work! wondering what codec KL/2 uses and if it can be supported? I'm PMing samples.
