The extracted audio files from Cyberpunk 2077 come in a .wem format, which is not useable like a conventional audio file.

Getting the Tool

To convert it into a .wav, this Blog Post demonstrates a quick way on how to.

1. Using vgmstream. Download the latest release from GitHub for your OS.

2. Extract the archive. For a quick one-time use, simply put the files in the same directory where your WEM files are located.

Using the Tool

Singular File

Once you have vgmstream ready, you can drag and drop the WEM files over the executable file (vgmstream-cli.exe in Windows)

Multiple Files

If you have a folder full of files, you can create a run.bat file in the folder, and give it the following content

for %%f in (*.wem) do "./vgmstream-cli.exe" -o %%f.wav %%f
pause

This will, once executed, convert every WEM file in this folder into a WAV. Given that the vgmstream executable is in the same folder.
