Forza Horizon 3 .Bank - unkown codec when extracted

[ZeroNull]

Anyone willing/interested in cracking the sound codec used in this game? I got a .Bank file and successfully extracted the FSB but it uses an unknown format when trying to extract the file to wav's.
All files seem to be in 48000Khz at a 210kbit bitrate when i open them in Aezay FSB Ext. Now i also tried FSBext and Fmodaudext but both result in distorted weird .wav files as it doesn't know exactly what format it is in.

Now i found some .Wav files that were just zipped and ready to play and it seems to use the same format that the .Bank files do : MS ADPCM 48000Hz mono 210kbps [A: adpcm_ms, 48000 Hz, 1 channels, s16, 210 kb/s]. This file played just fine in all media players.

So i suppose it should be fairly easy to compare the two and find out what is missing when converting the .Bank? Probably just some missing headers or something like that. Let me know what you can find out, i will attach the .Bank,FSB and the open working wav file for comparison.

try opening the extracted .wav in VLC, it should play it o.k., then you can "Convert/Save" to "audio - CD" format which will give you a normal pcm wave file. I've done this before with other FSB .wavs which were unknown codec and played distorted the same as you say.

Edit: just tried and it doesnt look like VLC knows it either. But I'm interested to know what it is.

[ZeroNull]

Exactly. I've been trying all kinds of players and importing the raw files into Audacity for example. But nothing seems to work,or come close to resembling a working recording of sorts.

It seems that Fmod has its own adpcm codec, Fadpcm format. Maybe this is the culprit?

., i tired with fsbext but extracts the files like 00001.dat 000002.dat not the original filenames

[aluigi]

The empty names are caused by the fh5.namesize field which is set to zero in the archive so it means that there are no filenames stored.
I can clearly see the names with the hex editor ("Peugeot*") but I have no way to know what to do when that field is zero (it may be a customization of the game or a new flag).
If you have fsb samples of other games that are extracted nameless but have a name in them, I will check them.

The tool fsb_aud_extr.exe extracts the filenames

[aluigi]

With fsb_aud_extr.exe and the FMOD libraries provided in the topic of the tool I get 00000000_0.wav in any case.

I have found what are these names, they are placed inside the list of information for each file and the type 0x8 wasn't supported by fsbext so I have just added it now.
In short they are not the name of the files but they are a sort of description.
The solution I adopted is to assign this field as filename if there is no filename.

fsbext 0.3.6

With fsb_aud_extr.exe and the FMOD libraries provided in the topic of the tool I get 00000000_0.wav in any case.

Before to extract the wav i dumped the FSB from the FEV and then i tried the fsb_aud_extr.exe

Extracting

fsb_aud_extr.exe GS_FOR_F150Raptor_17.bank.fsb
GS_FOR_F150Raptor_17.bank_0
GS_FOR_F150Raptor_17.bank_1

GS_FOR_F150Raptor_17.bank_6
GS_FOR_F150Raptor_17.bank_7
GS_FOR_F150Raptor_17.bank_8

And now with your new Fsbext

If i try to split the file with the tool fsb5_split.exe i get 1 file named ".fsb", lol

[aluigi]

Maybe there is something I don't understand because the output of fsb_aud_extr.exe there is exactly what I said: nameless files (input name + sequential number).
The difference now is that fsbext 0.3.6 gives you an alternative.

[Savage]

You right and the codec looks some adpcm

I have now succesfully extracted the soundfiles from a bank file using an newer fsb aud extractor. The only problem remaining is that the file names are missing. 00000000_102.wav etc. Anybody got some ideas how to solve the last issue?
