Well the SS0 is 1gb for double agent PC so its too big to post here.

But i had to extract all tracks inside of it, it only happens when i extract tracks in a batch or one by one in the file, And it does only on some files, not all.

So if i want to extract files i have to select everything and it will extract them with no errors, weird.

Well, thanks for the infomation. I'll try harder this time.

Thanks very much, Zench, for your work decoding UbiSoft's sound formats. I've been looking at Myst III for PlayStation 2, another UbiSoft game, and your info has been invaluable.

Unlike the Mac/PC version of Myst III, where all sounds and music are in individual WAV and MP3 files, the PS2 version appears to have everything in a pair of files: MAPS.SM1 (14 MB) and STRM.SM1 (433 MB).

Your DecUbiSndGui application figured out that STRM.SM1 contains 38 simple streams of the version 3 variety, all of the music in the game. I know that part of MAPS.SM1 is directory information. In particular, I've figured out how MAPS.SM1 describes the 38 streams in STRM.SM1. However, MAPS.SM1 is much too big to be only directory info. I'm sure that it must also contain audio data for the game's non-musical sounds. If so, it's in a format not recognized by me or by DecUbiSndGui.

If anyone is interested in looking at an example of a piece of MAPS.SM1 that I believe is audio data, here's the 8 KB chunk between a couple of the dozen or so directories scattered throughout MAPS.SM1:

Any suggestions on how to make sense of this data would be much appreciated!

I am always glad to help other people. Thank you for your feedback.

Yes, *.SM? files do contain audio (typically sound effects) as well as directory information. I should write a program that actually parses the directory information, but it varies from game to game. The segment you posted is not any UbiSoft audio format which I've seen. Keep in mind UbiSoft uses raw audio and platform specific codecs in their audio files (for example XMA on the Xbox platform). I am not very familiar with Playstation audio, though. Ahh... yes! I just tried this file in PSound (I can't remember where I found it) and it worked.

If you are able post the entire MAPS.SM1 file, I would very much like to examine it.

Brilliant! You're absolutely right -- PSound found 280 sounds in MAPS.SM1. Thanks for the help! Next step: google for a description of the PS2 sound format.

Here is the complete MAPS.SM1. My understanding of the directory structures is incomplete but I can tell you what I know, if you like. I don't have time to do so right now, though. Maybe tomorrow...

Here's my interpretation of the directory information inside MAPS.SM1. All values are little-endian.

Code: Select all

Header at 0x0000:
uint32 {4} - Unknown
uint32 {4} - Offset to root directory
uint32 {4} - Number of root directory entries, each 48 bytes long

Root directory entries:
{
	uint32 {4} - Unknown (always 0)
	uint32 {4} - Unknown (always 0)
	uint32 {4} - Offset to subdirectory
	uint32 {4} - Length of subdirectory
	char {32} - Subdirectory name, zero-padded
}

Subdirectory:
uint32 {4} - Unknown (always 0)
uint32 {4} - Offset to unknown table X (always 0x0024)
uint32 {4} - Number of X entries, each 52 bytes long
uint32 {4} - Offset to streamed sound table
uint32 {4} - Number of streamed sound entries, each 112 bytes long
uint32 {4} - Offset to unknown table Y
uint32 {4} - Number of Y entries? (usually 1)
uint32 {4} - Offset to unknown table Z
uint32 {4} - Number of Z entries

Streamed sound entries (apparently valid only if the length field at offset 0x0038 is non-zero):
{
	uint16 {2} - Sound ID, minor component?
	uint16 {2} - Sound ID, major component?
	uint32 {4} - Unknown
	uint32 {4} - Unknown
	uint32 {4} - Unknown

	uint32 {4} - Unknown
	uint32 {4} - Offset of version 3 simple stream in STRM.SM1, only if length > 0
	uint32 {4} - Unknown
	uint32 {4} - Unknown

	uint32 {4} - Unknown
	uint32 {4} - Number of channels (always 2 when length > 0)
	uint32 {4} - Sample rate (always 44,100 when length > 0)
	uint32 {4} - Unknown

	uint32 {4} - Unknown
	uint32 {4} - Unknown
	uint32 {4} - Length of version 3 simple stream in STRM.SM1
	uint32 {4} - Unknown

	uint32 {4} - Unknown
	char {8} - File containing streamed sound (always "STRM.SM1" when length > 0)
	uint32 {4} - Unknown

	uint32 {4} - Unknown
	uint32 {4} - Unknown
	uint32 {4} - Unknown
	uint32 {4} - Unknown

	uint32 {4} - Unknown
	uint32 {4} - Unknown
	uint32 {4} - Unknown
	uint32 {4} - Unknown
}

Following almost every subdirectory and its tables are PS2-native sequenced sounds.

Unknowns:

• Purpose and structure of tables X, Y, and Z.
  Purpose of many of the fields in a streamed sound entry.
  Purpose of the many streamed sound entries where length == 0.
  How sequenced sounds are described in a subdirectory.

I hope this is of use to someone.

Arg! finally able to log back into xentax! (changed emails took forever to get reactivated).

[Zench]

Here's my interpretation of the directory information inside MAPS.SM1. All values are little-endian.

Nice work! The general structure is very similar to the other *.SM? files I've seen, except that this one has lots of padding an the other ones don't. That's probably just a Playstation thing, though. I should post the format of the Splinter Cell 1 PC .SM0 file so you can see how similar they are. I should also add a bunch of UbiSoft audio formats to the wiki. I already started adding a few but I didn't finish. If you want to add this format and know how, go ahead; otherwise I can do it.

We're glad to have you back!

Please do. There's no hurry, though. I'm curious but I don't have that game.

If you want to add this format and know how, go ahead; otherwise I can do it.

If you're sure you don't mind, I'd appreciate that.

Hey zerichs will we see another version of the GUI?

[Zench]

Hey zerichs will we see another version of the GUI?

It's likely. I've been thinking about adding a few new features (like layer extract). I was also thinking about how I can get it to read .SM? files, if possible. I'm not sure if I fixed the bug you mentioned yet. It isn't high priority, though.

[Mirrodin]

Sweet! I am still promising tutorials of the program. I'm still breaking down the tutorial structure so it may be a while before I post anything, But i'll be sure to link and give credit to all who are involved. If anyone has any suggestions on whether they'd like to see a game-specific tutorial series, or a general tutorial covering specific functions of the program (regardless of game), please feel free to comment! I haven't actually started writing them yet. but I will asap when I get some feedback from you guys!

[RonHayter]

Here is the .SM0 format from Splinter Cell 1 and 2:

You're right, there are many similarities with the format of MAPS.SM1 from Myst III for PS2. Thanks.

Do you have any idea how the offsets to the sounds that are inside MAPS.SM0 are determined? I still haven't figured that out for Myst III.
