We actually don't need debugging. We just need ADPCM tables for this codec.

I didn't decode the first sample. It is saved in the ADPCM block unchanged. This is what I wanted to check and it was successful.

ok, it is really different. 128 samples instead of 64 in MTA2, and probably another algorithm. I will keep you informed. bgm_mgo_lobby01.bgm has 12-channel streams. Weird. Maybe that are 3 parts of one 4-channel music track.

Yes I found his source, but now we need to know how different is MTA2 from MTAF. It may be very different.

One user asked me if I can look at the sounds from Metal Gear Solid 4. So I checked bgm_mgo_title01.bgm and it looks like 4-channel audio encoded as ADPCM of some kind. 64-sample blocks. If we take first (uncompressed) samples from each block, this is the picture: http://oi61.tinypic.com/10wjixj.jpg...

The format in Medal of Honor 2010 reboot is similar, but different headers, and most sounds are in Ealayer3 version 5. Yet some are still in XAS. I can decode them all I think.

Yes, if I combine these pieces one by one, can hear a perfect music file.

I've got the music decoded. In each music bank there are about 100-200 audio files. Some are complete music pieces, but most are short fragments, combining which you can compile music tracks, or loop them infinitely. There must be some script in the game to do this, but currently I can't find it or ...

The format in that "reboot" may be totally different, so you better send me a sample of its music bank.

Ok, I removed them.

Audio extractor for Medal of Honor Currently only tested on "Medal of Honor: Airborne" and "Medal of Honor 2010" but may work with other EA games with Unreal Engine. Medal of Honor: Airborne If you unpack .xxx packages with Gildor's extractor you get a lot of files of type .Sound...

Ok, tools uploaded. Have fun :) It is strange, but many .xxx files have strange (encrypted?) part in the beginning. Different size, but all about 32k. Interesting that first 31184 bytes of those are the same for all .xxx files. It doesn't affect the unpacking process, but what could that be? Any ide...

MKX .xxx unpacker. Experimental tools, 64 bit only. No error handling, no help. Here's what you can do with it: 1. unpack xxx file mk10_xxx_packer [xxx name] It will make unpacked .xxx.u file. If the file is already unpacked, it will crash. At least sound .xxx are not packed at all. 2. list the cont...

There's not many choices today: first you cut .fbs files from .xxx with Luigi's script, then decrypt them with his tool "fsbext". The script and encryption key are on top on this thread: http://zenhax.com/viewtopic.php?f=6&t=833

First you need to extract .fsb files from .xxx package and decrypt them.

A little mistake found in wav header (data length calculated twice longer). Updated the old post:
