Electronic Arts MGAV audio variant

[BloodRaynare]

Can anyone help me to remove the chunks from MGAV audio used by EA in some of their games to become playable PlayStation ADPCM?

Here's the sample file (it's from NASCAR Rumble, MGAV variant)

MENU.zip

(note: the filenames and extension were made up by me. I'm actually extracted the files from the game's TRK archive with hex editor.)

the MGAV structure I gathered so far from opening them in Hex editor:

0x00 - 0x3F = file header

data starts at 0x40 (Actually it's just a normal PlayStation ADPCM).

each 0x5F80 of the data there's a chunk with string "LLIF". the first chunk (offset 0x5FC0) has a size of 0x5C, then the rest of chunks was 0x80, and then at the end of the file there's another chunk sized 0x64.

Thanks for the solution (By the way, I have a quicker way to do it.)

1. Extract the chunks with gen_split.bms script
2. Cut the 24448 bytes (offset 0xC - 0x5F8B) for each chunks with vgmtoolbox.
3. Then concatenate those cutted chunks with HxD Hex Editor's concatenate feature
4. create the genh with VGMToolbox with these settings:
Format: PlayStation 4-bit ADPCM
Headerskip: Leave it blank
Channels: 2
Frequency: 14250 (PSX EA games which used that format usually using this frequency, well it's my guesses after all)
Interleave: 0x2FC0
Loops: No Loops

Solved. It's been playable directly with the current version of vgmstream without need to convert it to another format.
