Its normal MP3 with their own custom header and the weird "uncompressed samples" stuff at the end.

uncompressed samples may also be in the beginning if i remember correctly

Ok so I think I finished playing with EALayer3 now. Things I discovered (and that aren't in the "ea layer 3.txt" file in the ealayer3 code)
For "version 5" data, the first 8 bits have to be 0xEE for the "uncompressed samples present" code to trigger, not "non zero" as the docs imply.
For "version 6/7" data, the second bit in the header (currently marked "unknown") is channel count - 1 (so 0 for mono and 1 for stereo)
The enum used for the "mode" flag in the extended header for "version 6/7" data looks like this
enum rw::audio::core::BlockOffsetMode
{
BLOCKOFFSETMODE_IGNORE = 0x0,
BLOCKOFFSETMODE_PRESERVE = 0x1,
BLOCKOFFSETMODE_MUTE = 0x2,
BLOCKOFFSETMODE_MAX = 0x3,
};
And finally, the function that decodes the "uncompressed" sample data in "version 5" files is named DecodeSpecialBlock. For "version 6/7" files the decode function is named DecodePcm. Not sure why they called it a "special block" for the "version 5" files, just seems weird that they did that.

That's it for interesting EALayer3 discoveries

Just wanted to say thanks for figuring out that .mus stuff.
There is a related file format (doesn't contain actual audio data but will contain references to the .mus file) called .mpf. I have uploaded a sample mpf file here. The MPF file is connected to data called "PathMusicMap" by the game.
https://mega.nz/#!e9ExFLbY!7uqs3qW-uHb0 ... Nq_FgdpBB0
If anyone can help me figure out its format, I would be very grateful (its one of the only formats in Red Alert 3 that can't currently be edited)

Checked the file. If anyone will be going to figure out its format, he will also need the files that its connected to. Maybe even the whole game. Because it doesn't contain actual data, but only references, its natural that'd be impossible to figure anything out without the actual data it refers to.

As far as I am aware, the only data that the mpf file (which goes with the PathMusicMap data) should be referencing is the PathMusicTrack data (the .mus file). The game has 2 of them, the smaller of the 2 is what I uploaded earlier.

I suspect the best way forward is to go back to my reverse engineering notes from before and continue reverse engineering as much as I can and then write it all up (with data structure definitions, notes and mega.nz links to the various data files involved) and then see if anyone out there can help me fill in the blanks.

I have posted all my notes on the PathMusic stuff in viewtopic.php?f=17&t=14927
Hopefully someone will be able to help me reverse engineer all the remaining pieces in the files so its possible to change these files and mess with this data...

Sorry to bump this forum but i just want to ask...

searching the BF1 Soundtrack somewhere in "sound" folder, found all the EBX File but dunno how to figure out where is the audio (Soundtrack) files located, because some of them are kinda like a trap file for me (some of the EBX are not the Audio Files)

Did you look in the "Levels" subfolder in the main folder "Sounds" after sound extraction? I remember clearly finding musics loops and stuff in that subfolder (like the epic fight music "Metal Frenzy" in the Storm of Steel mission: "Sounds\Levels\SP\E0\Music\SP_E0_Prologue_CombatInfantry4CH_Loop_Wave 0 0 0.wav"). You will even be able to find unique sound effects only used in those levels, in the same directory (like, again in the prologue, the scream of the guy who's rushing at the character in the outro), if you're interested.

But, if you're looking for the musics in the background from the main menu (like Dawn of a New Time, that I personaly love to the bones), check this subfolder: "Sounds\Music\FrontEnd"

Heya. I was curious is there a read me file or tutorial somewhere for this tool?
I'm trying to extract need for speed hot pursuit 2010's audio files from their BNDLs, but can't extract them into a readible file format for the exe only as empty .ealayer3 files.
I'm sure the issue is user error on my behalf.

I've attached pics of the console commands ive tried and the current folder setup if that helps.

Hello everyone, I am trying to use EA Layer 3 to decode an SPS sound file from NFS Most Wanted 2012 of PS Vita but it doesn't work. It says: It works fine when extracting the same sound from the PC version of the game, but I want to be able to use my Vita files.
Here are the files mentioned:
PS Vita 14729.SPS
PC 14729.SPS
PC extracted 14729.mp3

That PS Vita file seems to be compressed or encrypted.

I figured that might be the case. I guess they might be compressed since the majority of them have almost half the size of the PC version. I tried looking for any possible headers of this filetype in the PS Vita version of SPEECHEVENTSEQUENCES.SWC0 (in the PC version it's multiple SPS files glued together). Unfortunately I wasn't able to figure anything out on my own.

I would be very grateful if you could give me a hint or two as to how to go about this. I can provide the whole PS Vita game files and any from the PC version for comparison if needed.

Essentially what I want to do is replace the sound files the game uses for when you are near a jackspot with a file of no sound. It's pretty annoying when it plays on top of the in-game music and there's no way to turn it off..

I have no idea how to create files for Def Jam Icon but if I use --verbose on one of the files it gives me

Hello does this work for windows 10?
