Amplitude .ark (multitracks, stems) decryption

Hi,
I was trying to get the multitracks and loops out of Amplitude, so I started to work with the .str files. Unfortunately it was only possible to extract a .wav file out of it and that was not the multitrack folder. The multi-channel songs are in the "main.ark" data but of course I can't extract anything. That arktool programm doesn't work and I managed to find a line in that file
Code: Select all
Decrypt_28L....Decrypt_28R [...] R:\FREQ2\FreQ2_Metagame\Song Encrypt Audio\Decrypt_28L.wav:...R:\FREQ2\FreQ2_Metagame\Song Encrypt Audio\Decrypt_28R.wav
Many of the Files are in .wav format (ps2 console! wtf?!)
Code: Select all
R:\FREQ2\FreQ2_Game Levels\David_Bowie\Wav Slices\Bass\Bassloop1_22\Bassloop1_22 right 008.wav
R:\FREQ2\FreQ2_Game Levels\supersprode\Wav Slices\Bass\qy_chor_blipbass\qy_chor_blipbass 22K\qy_chor_blipbass_44 030_22.wav
Any suggestions how to open, encrypt or extract that file? This game is from Harmonix and people managed to hack GH1/RB1 - 2009, so a game from 2003 should be easier? Plus it contains extremely rare loops. Any RB or GH hacking vets here?
Thx for your help

no file no party :)
that 28L and 28R sounds like left and right, maybe it's a simple rotate_left/right?
would be too simple, anyway I can give it a 30 seconds look

should I upload parts of the file or sth? I don't have a clue what to do and the encrypted files would be incredible great...

as far as I have understood only the wav files are encrypted right?
so start uploading one of them (the smallest)

No the thing is, I only have the .ark file and the .wavs, .bnk and loops are in it. I have no idea how to extract them and even if I could do that, they would be encrypted (as good as it was possible for harmonix in 2003). I can upload the "main.ark" file (over 1GB) if you think that you are capable of doing sth with it.

maybe upload only the first 10 megabytes.
but as it sounds it doesn't seem something on which I can do something

If you can't do this: do you know any user who is experienced in such things?

try this one with quickbms:
Code: Select all
# Amplitude
# script for QuickBMS http://aluigi.org/papers.htm#quickbms
get DUMMY long
get FILES long
math OFFSET = FILES
math OFFSET *= 20
math OFFSET += 8
goto OFFSET
get SIZE long
math OFFSET += 4
log MEMORY_FILE OFFSET SIZE
math OFFSET += SIZE
goto OFFSET
get ENTRIES long
savepos OFFSET
math SIZE = ENTRIES
math SIZE *= 4
log MEMORY_FILE2 OFFSET SIZE
goto 8
for i = 0 < FILES
get OFFSET long
get NAME_OFF long
get FOLDER_OFF long
get SIZE long
get DUMMY long
math NAME_OFF *= 4
goto NAME_OFF MEMORY_FILE2
get NAME_OFF long MEMORY_FILE2
goto NAME_OFF MEMORY_FILE
get NAME1 string MEMORY_FILE
math FOLDER_OFF *= 4
goto FOLDER_OFF MEMORY_FILE2
get FOLDER_OFF long MEMORY_FILE2
goto FOLDER_OFF MEMORY_FILE
get NAME string MEMORY_FILE
string NAME += /
string NAME += NAME1
log NAME OFFSET SIZE
next i

Thank you so much, you are incredible!!! It worked perfectly. Now I have to find the song files... I spotted the "sound" folder with .bnk files in it. I don't know if they contain the loops but there are also .mid files of the songs, so it has to be the right one.
what do you say?:

the str files seem to contain raw audio at 32khz, 16bit stereo.
it sounds a bit noisy so it's not to be excluded a light codec used on it (adpcm?)
the rest seems almost like a midi and sound instruments, for sure an "original" solution.
anyway there is for sure someone with more experience than me that can say something useful

The .str is a preview. Thanks to Jaeder Naub, which can convert .str files into .wavs. Well I hope that someone can help...

Push. And 25$ or more payment for the first one who can decrypt the files. I need the loops and stems, then I'll pay

Hopefully this is an incitement for you

does the script work on the whole ark file as it only extracted around 5mb worth before it gave an error extracting from an offset?

The script should work, it extracted everything from the main.ark file (arenas, attract, audio, cnf, ...). Are you using the full game (.iso file)?
