Heya! Welcome to my very first guide. So please bear with me if I make some mistakes here and there. I will try my best to correct them.

Like I said above, I'll try to keep it as newbie friendly as possible so even if you have the most basic knowledge of browsing the internet, you should be able to complete what's written on the guide.

However, I do want to apologise to all the users who are at least tech savvy enough that you would not be getting a 'straight to the point' type guide. There will be quite a lot of scrolling.

Whilst everything here can be found externally on another site, there is no (or at least I cannot find) one guide that explains the full process of extraction and conversion (from .pak/.ucas to .wav/.ogg) and if there is, it's definitely not on Steam (else I'm just blind then)!

Last but not least, please do enjoy the guide and hope your process is smoother than writing this guide!

There's a few programs that we need to download and install before starting the extraction process. You can skip this section if you already have all of these programs or do not require help navigating to the downloads of the program.

---

This program is the core program used to extract files from .pak or .ucas files. You cannot individually download UnrealPak. The only way is to install Unreal Engine from the Epic Games Launcher. You can find the download link below if you don't have it. Skip this part if you already have it.

Epic Games Launcher Download[store.epicgames.com]



Once downloaded, launch it, install it and go through all the steps. It's super easy. After installation, open the launcher and it should ask you to log in. Log in or create an account.

---

Once you're in the launcher, head on over to Unreal Engine on the side bar.



Press Install and let the launcher do its work. The button is on the top right. (Unreal Engine is already installed on my machine hence it says Launch).



After installation, it might open, just close it. From your desktop:


Scroll down and find UnrealPak or type "unrealpak' on keyboard without selecting anything. It should look something like this.



Minimise the window upon finishing. We will come back to this later.

This program is used for the conversion process. Foobar2000 is another one of your basic audio player except we will be installing a plugin that allows it to read the .WEM files that we will find after extracting without the need to install Wwise nor do any scripting with quickbms on ww2ogg and revorb. This audio player also allows us to export the file from .WEM to any chosen audio file, expecting that we have correct encoders for. You can find the download links below:

Foobar2000 Audio Player[www.foobar2000.org]


Foobar plugin[www.foobar2000.org] or Foobar plugin alternative[vgmstream.org] They are both the same files, in case one link fails. Scroll down to find the download.



Please make sure that you install the audio player first before running the plugin. That should entail for smooth installation. You can skip to the next section if you do not wish to convert your files to something other than the defaulted .WAV.

---

In the event where you want to convert your .WEM to another audio file extension that is not .WAV. You can download this encoder pack and install which lets you choose to convert to another extension explained in its respected section.

Now that we have all the required programs installed. Hover over any Unreal Engine game that you want extract.


That should open up the game directory in a new window. Your directory may look something like this.



Navigate through the directory until you find the Paks folder. In my case it is:




Now look for a large size file that ends with the extension .PAK. This will be the input. In some cases where there are several large Pak files, you may need to repeat the extract process.

Create a new folder, can be anywhere. For convenience, create the folder within the same location by:


Name it whatever you want. Do not open it.

---

Now the real part begins! From your taskbar, search cmd. Open it.


Get the window that you minimised earlier. It should be named as Win64

For the experienced, follow this format, replace with what you need. Then skip this part and head to the next section, otherwise troubleshooting.


For the unexperienced, drag and drop UnrealPak into Command Prompt.



Select the window and add a Space. Then from the Paks folder, drag and drop the PAK file you want to extract.



Select the window again and add another Space followed by
then another Space.



Drag and drop the new folder you created earlier into the Command Prompt. Before you hit Enter, it should look something like this. Make sure everything was done right.



Hit Enter. The extraction process should take a few seconds to minutes depending on the size of the PAK file. Your results should look something like this, if it successfully extracted. If it was not successful, head on over to the Troubleshooting section.



Extraction completed. Well done. Close all windows except the extraction folder. Open it if you haven't already.

Navigate through the files until you find 'WwiseAudio'. My path looks like this.*


Here in this folder contains most, if not all, your audio files related to your chosen game.



If you go into the Media folder, that will contain the .WEM files that we need to convert.

For that to happen, open Foobar2000 from your taskbar.



Now in the program, drag and drop one or multiple .WEM file into Foobar2000. Double click to listen to them and it should start playing through your default output device.

Once you find the .WEM file that you wish to convert.**




And a smaller window should appear.



By default, it should be selected to WAV. If you did install the optional encoded pack, feel free to change it to another one. Choose a save location on where the converted file should appear. Click Save.

Voila! You have converted a .WEM file to .WAV (or whatever you chose).

*Note: You can convert .BNK files too. Find the ones that aren't 1KB. BNK files usually contain more than 1 track.
**Note: It is possible to convert multiple files at once. Just highlight all tracks you wish to convert.

Sometimes during the extraction process, it will bug out and convert the PAK file into a 1KB PAK file. Luckily, the solution is very simple. Hover over the game you wanted to extract:




Wait for this process to complete and Steam will redownload the required files. The directory will be good as new.

If your error looks something like the above, there is probably a good chance that you may have strayed off from the guide and opened Windows Powershell instead without knowing. Meaning you probably went
Worry not! I did this as well and was 'feeling dumb' when I realised. Open Command Prompt and retry.

Well, this is the end of the guide. I actually have no clue what to put here. So I'll keep it short.

I do hope that it worked out for you like it did for me. If you somehow come up with more errors than I encountered, I'll try and replicate it to find the solution. I'm not super tech savvy but I can get by.

The next section is dedicated to Life is Strange: Double Exposure. It's also the main reason why this guide is posted within the game content area.

Anyways, have fun. I found most of the songs in the game. We already have it downloaded from the game but important to not share it online!

**This section is purely related to Life is Strange: Double Exposure**

DO NOT UPLOAD UNRELEASED SONGS - I AM NOT RESPONSIBLE FOR ANY LEGAL ACTIONS TAKEN AGAINST YOU

The following .WEM files are associated with the songs.

For anyone that wishes to obtain voice overs or sound effects. To make your life a little easier to understand the filenames, I'll go over them. The terminology is quite simple.
AMB - Ambiance
AdminBuilding/FAB - Map location
E1_S1A - Episode 1 Scene 1 Part A
SFX - Sound Effects
MUS - Music
MX_Globals - Universal menu music

Each folder with the language as its filename should contain all of each episode's voice over dialogues.
