Eternal Darkness Audio Formats by Dark_Ansem at 8:04 AM EDT on August 27, 2014
I'd love some help in understanding the audio formats of Eternal Darkness, excluding BGM as VGMstream can already read them.

\audio\stream folder files present a structure similar to this, in Hex, as they have no extension:

..CE...+..}.....
.......+........
.........A......
..._.(.....1...c
................
................
c.. ...1..?....
"n...O./!.o_%.r4
q.X@..Y_b...!..%
".?.....Qc0`1.Q.
!C.@..Ua".2"S.B.
a~'.B1.M!...`...
x.....R.h,.v..4.
w. ../.|..cEd .3
v4..;.._W.." ..%
w:.\./.5w...B.L.
'.A.3.........q.
UF..B=..F.......
v.Q...K.62.A..2.

\Autopsy files are .aud files that vgm stream CANNOT play. they are possibly audio files, since each movie in-game has one .aud file attached.

the \effects folder has .poo, .pro, .sam., .sdi
those are very probably archives, but that's just my 2 cents.

profiding link to sample of each filetype...

Ah, looks like another MusyX game. Sorry to say, but I think it's sequenced (at least ed_fx), which means you'll either need a dedicated component to play them back (and afaik no one knows how MusyX format works yet), or convert them into an appropriate format that will play back in your audio player (e.g. midi+sf2), and even then, to do that, you still need to know how MusyX works obviously.

For what it's worth, I made a sample extractor for MusyX games a while ago if you're interested. Pretty sure it'll work for this game too. http://hcs64.com/mboard/forum.php?showthread=36979 (see the last post on the second page for an updated version)

EDIT: tried it on the files you uploaded, and indeed it works.

I expect the .aud files can probably be handled easily with a modification to vgmstream, though, I encourage someone to take a look.

@nisto: it did, they work in VGMstream. many thanks|
some of them don't work tho :( or they're super-brief, I can't decide. used 0 as extraction format. perhaps an update to the script, please?
EDIT: nvm, apparently converting them to WAV enables them all, kinda.

@hcs: I agree with you, I seem to remember vgmstream can already read AUD files, just not those ones.

what about those files without an extension? how to get audio from those, the "streamed" audio?

looking through HEx the streamed files, nothing good for me however, have you had better luck?
by Dark_Ansem at 6:11 AM EDT on September 2, 2014
Nisto, I believe the extractor does not get the sfx tempo right, how can I fix that?
by Dark_Ansem at 9:26 AM EDT on October 18, 2014
Nisto, any good news for me?
by Nisto at 1:47 PM EDT on October 18, 2014
Oh, sorry, must have missed your previous post. Can you re-upload the sdir/samp files again? And which sample has incorrect tempo?

Keep in mind that the tempo of the samples doesn't necessarily have to be the same as that of the note from the game sequencer, so you might have to manually adjust it if you want it to sound like it does in the game.

happy new year!
dammit no notifications make very hard to follow.

Nisto, there are several other files not recognized, can I upload them too?
by Nisto at 2:24 AM EST on January 16, 2015
Sure thing

Hey there, I've been wondering if there's been any progress on this, since I've been trying to extract the audio of this game for a while, myself.

I also got everything in the effects folder extracted and converted perfectly (and BGM worked anyway) but no tool seems to be able to do anything with the files in the Autopsy (.aud), Cinematic (also .aud) and Stream (no extension) folders...
by Dark_Ansem at 5:51 AM EST on March 5, 2015
I know, I've tried to fix that for ages. VGMstream knows how to play AUD files but not those ones...

Reviving this thread because of the awesome progress that has been made in VGMstream recently! I'm going to post all the audio-related folders from the game and whether or not they are decodable:

PARENT FOLDER /Audio:

/Autopsy: .AUD files, all decodable with the latest VGMstream (Custom Vorbis).

/Cinematic: same as Autopsy.

/Effects: MusyX files, all decodable as .dsp with the latest version of Nisto's musyx-extract. The only .dsp files that I couldn't play are "00323 (0x0143).dsp" ("boss" folder), "00363 (0x016B).dsp" and "00355 (0x0163).dsp" ("fx" folder). The "menu" folder files all work perfectly (remember, the menu sounds are stereo songs, each split into two mono files!).

/Music: .ADP files, already in the joshw drive.

/Stream: Extension-less files. Rename them to .DSP and you're good to go. The files labelled "l" and "r" are automatically joined and played back as stereo in foobar2000 when you play any of the two files. The rest are mono.

PARENT FOLDER /FMV:
Again, the .AUDs are now playable as Custom Vorbis. Have we figured out a way to play .h4m videos?

These are all I've figured out so far. The rest of the files in the game that I don't know how to decode or extract are in the folders /Ai (.dat), /Chars (.bin, .cpk, .tpl), /Cinematics (extension-less), /Credits (.cmp), /Rooms (.bpe) and, of course, the .h4m videos in /Fmv.

Aren't they compressed? Has that been broken. Or maybe audio is not?
by Dark_Ansem at 6:42 PM EST on February 22, 2018
I've been having another go at this. I'll let you know.
by Dark_Ansem at 7:00 PM EST on February 22, 2018
OK, so I double-checked. Whatever method I used before, taking WAVs out, extracts the same files. However, there is an issue: audio files aren't sometimes extracted as they are heard in-game. Is it possible the game alters their pitch/tempo?
by Dark_Ansem at 5:38 AM EST on February 23, 2018
and BTW: a big thank you to the guys.
by Dark_Ansem at 10:57 AM EDT on March 28, 2019
Got the DSP out, collection almost complete but something appears to be missing.
by AdeleHouck at 10:27 PM EDT on April 7, 2019
Speaking about such types of format, we can find a lot of variants to be done with the help of modern tools and equipment. Nevertheless, there are several eternal ones described here and the most popular because of this.

What are you talking about AdeleHouck? That's just a Wikipedia link.
by AdeleHouck at 11:49 AM EDT on April 25, 2019
I guess a mess with link happened
by Dark_Ansem at 11:54 AM EDT on April 25, 2019
link again please?
by Dark_Ansem at 12:01 PM EST on February 17, 2020
Has there been any progress on this? Such as how to get filenames out?
Eternal Darkness Audio Formats by vgbywb at 8:08 AM EDT on October 24, 2020
Wow! At least I'm not the only one who's reply on this in 2020...

I was able to get few sounds and tracks out of the game files with a GC extraction tool.
When it comes to those .AUD files I struggling get the damn audio out of it...

Thanks to this thread I'm motivated trying another run.

Let's start with research and determining the proper file format
