A downloadable tool for Windows

This is a sound effects mixer. It can be used in Game Maker projects as a tool to help audio designers mix their sounds for game projects.

It acts as a simple draggable window interface that lists every sound that is contained in your project and lets you change the audio_sound_gain() values for each individual sound. It supports external saving/loading, meaning you can save these values to an INI file anywhere on your PC to share with other members of your team.

  • Mix sounds live in-game with instant playback of current sound
  • Automatic saving/loading
  • Use Shift/Control to select multiple sounds
  • Open/Save functions for easier sharing

To install this extension, simply drag and drop it into your project.


  • Before compiling your game as an .exe build, include the "sfx.ini" file into your project. The game will not find it otherwise.
