PD3AudioModder

A small program for editing and viewing PAYDAY 3's audio files.

For more complex replacement, it is recommended you follow this guide by Gamest23 instead.
This tool may have trouble replacing lines like enemy voicelines, and other more scripted lines like that.
Otherwise, this tends to work fine for simple replacements.

Editing:

Converts the audio file to WAV, 16 bit signed little-endian using ffmpeg, then converts that WAV file to WEM using wwise_pd3, and then finally replaces the ubulk file with that WEM, and edits the uexp file to have the size value that's inside the json file (fixes corrupted, glitchy audio).
The program will prompt you where you want to save converted files.

Also has the option to pack files for you using repak if you wish.

Viewing:

You can load the game's pak files, search through all the audio, including their IDs and names, export the audio files as raw data (.uasset, .ubulk, .uexp, .json), or save them as .wav files, all inside the ID Search tab.

⚠️ Crashed?

The app automatically makes a crashlog file inside of your AppData's Roaming folder.
You can get to this by hitting the windows key + R, typing %appdata%/PD3AudioModder/Logs and then clicking ok.
A crashlog is very useful to identifying what went wrong, and providing it in a Github Issue or the comments here helps greatly. Thanks.
