Adding Audio to your Mod

  1. Create a folder in your Atlan mod called audio.
  2. Copy your converted WEM file(s) in there and make sure they have the same ID as the audio file you want to replace. Any content prior to id# is irrelevant.
    ( ex: samuelsbase_music_main_heavy_0_0_id#15098487.wem )
  3. Package your mod, then run the AtlanModLoader.

Legacy - FFmpeg ( SFX & VO ) - Eternal Mod Injector

You need the FFmpeg extension for Audacity to import/export OPUS audio files - Download

  1. Install ffmpeg-win-#.#.#.exe -> Follow the installation instructions
  2. Open Audacity -> Edit -> Preferences -> Libraries
  3. FFmpeg Library: Locate... -> Browse... -> Find avformat-55.dll -> OK
  4. SFX & VO: Convert all of the audio you want to export to OPUS.
    ( Export Audio -> OggOpus - 64 kbps for high quality )

Be sure to export the OPUS file in either mono or stereo depending on the format of the original file.

Sometimes, Audacity will automatically find avformat-55.dll

If the exe version does not work, download the zip option and extract it into a new folder called ffmpeg-win-#.#.# (depending on the version number) and extract all its contents in there. Then attempt to locate FFmpeg.
