A GameMaker: Studio and GameMaker Studio 2 extension that provides GML bindings to the FMOD Studio low-level API. Can be used in Windows, macOS, and Linux games.



The project is on hold for the time being. Work on this project is mainly done by me and I don't have as much time as I did in the past to maintain, add features, and keep up with the development of FMOD Studio. There might be a time when I'll come back to work on this, but I'm not certain when that will be.

If you want to contribute to the project, feel free to create a pull request. I would like to thank Gitle Mikkelsen (Grix), rissole, and BPzeBanshee for their past contributions to the project.

  • Load and play a wide variety of audio formats not natively supported by GameMaker:Studio (e.g. MP3, MIDI, MOD, S3M, XM, IT, etc.).
  • Play MIDI files using DLS1 sound banks.
  • Add custom loop points to sounds. This allows, for example, a music track to have an intro section that can seamlessly transition into an infinitely looping main section without having to break them up into two separate files.
  • Dynamically change to volume, playback frequency and relative pitch of a sound.
  • Analyze an audio stream using Fast Fourier Transform (FFT) and obtain its spectrum data.
  • Support for DSP effects such as flange, reverb and filters.
  • Extract tag information from audio files (e.g. ID3 tags from MP3s and Vorbis tags from OGGs).
  • Supports various audio output modes (e.g. ASIO, WASAPI, ALSA).

Basic Usage

// Optional: Check to see if FMODGMS has loaded properly
if (FMODGMS_Util_Handshake() == "FMODGMS is working.")
    show_message_async("Success! FMODGMS has been loaded.");
else {
    show_message_async("Error! FMODGMS was not loaded prorperly.");

// Create the system

// Initialize the system

// Load sound
sound = FMODGMS_Snd_LoadSound(working_directory + "sound.ogg");

// Create a channel
channel = FMODGMS_Chan_CreateChannel();

// Play sound

Possible Features in the Future

  • More options for FFT and spectrum data functionality.
  • Android support.
