CSGO voice extractor

CLI to export players' voices from CSGO demos into WAV files.

Valve Matchmaking demos do not contain voice audio data, hence there is nothing to extract from MM demos.

Installation

Windows

1. Download the last release from GitHub
2. Copy/paste the following files from the CSGO installation folder next to the executable:

• tier0.dll
• vaudio_celt.dll

Note
By default, these files are located in C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\bin

macOS

1. Download the last release from GitHub
2. Copy/paste the following files from the CSGO installation folder next to the executable:

• libtier0.dylib
• vaudio_celt.dylib

Note
By default, these files are located in ~/Applications/Steam/steamapps/common/Counter-Strike Global Offensive/bin/osx64

Linux

1. Download the last release from GitHub
2. Copy/paste the following files from the CSGO installation folder next to the executable:

• libtier0_client.so
• vaudio_celt_client.so

Note
By default, these files are located in ~/.steam/steam/steamapps/common/Counter-Strike Global Offensive/bin

Usage

Windows

csgove.exe demoPaths... [-output]

By default .dll files are expected to be in the same directory as the executable. You can change it by setting the LD_LIBRARY_PATH environment variable, example:

LD_LIBRARY_PATH="C:\Users\username\Desktop" csgove.exe

macOS

Warning
The environment variable DYLD_LIBRARY_PATH must be set before invoking the program and point to the location of the .dylib files!

DYLD_LIBRARY_PATH=. csgove demoPaths... [-output]

Linux

Warning
The environment variable LD_LIBRARY_PATH must be set before invoking the program and point to the location of the .so files!

LD_LIBRARY_PATH=. csgove demoPaths... [-output]

Options

-output <string>

Folder location where audio files will be written. Current working directory by default.

-exit-on-first-error

Stop the program at the first error encountered. By default, the program will continue to the next demo to process if an error occurs.

Examples

Extract voices from the demo myDemo.dem in the current directory:

csgove myDemo.dem

Extract voices from multiple demos using absolute or relative paths:

csgove myDemo1.dem ../myDemo2.dem "C:\Users\username\Desktop\myDemo3.dem"

Change the output location:

csgove -output "C:\Users\username\Desktop\output" myDemo.dem

Developing

Requirements

• Go
• GCC

Debugging is easier on macOS/Linux 64-bit, see warnings below.

Windows

Because the CSGO audio library is a 32-bit DLL, you need a 32-bit GCC and set the Go env variable GOARCH=386 to build the program.

1. Install GCC for Windows, TDM-GCC is recommended because it handles both 32-bit and 64-bit when running go build. If you use MSYS2, it's important to install the 32-bit version (pacman -S mingw-w64-i686-gcc).
2. Copy/paste tier0.dll and vaudio_celt.dll from the CSGO installation folder in the project's root folder.
3. CGO_ENABLED=1 GOARCH=386 go run .

Warning
Because the Go debugger doesn't support Windows 32-bit and the CSGO lib is a 32-bit DLL, you will not be able to run the Go debugger.
If you want to be able to run the debugger for the Go part only, you could comment on lines that involve C/CGO calls.

macOS

1. Copy/paste libtier0.dylib and vaudio_celt.dylib from the CSGO installation folder in the project's root folder.
2. DYLD_LIBRARY_PATH=. CGO_ENABLED=1 GOARCH=amd64 go run .

Warning
On macOS ARM64, the Go debugger breakpoints will not work because the executable must target amd64 but your OS is ARM64.

Linux

1. Copy/paste libtier0_client.so and vaudio_celt_client.so from the CSGO installation folder in the project's root folder.
2. LD_LIBRARY_PATH=. CGO_ENABLED=1 GOARCH=amd64 go run .
