We’re happy to announce a new release of the **FMOD extension for Defold** 🎧 ![defoldfmodbanner](https://forum-defold-uploads.b-cdn.net/original/3X/5/1/51437eea12de5316540000f5e9986db3c65bf1e8.jpeg) Originally created by Marius @dapetcu21 ❤, the extension has been forked and brought up to date and maintained by the Defold Foundation over the past year, with the goal of making [FMOD](https://www.fmod.com/) a solid option for developers who need more advanced audio workflows in Defold projects on all platforms. The extension now supports **FMOD Studio and Core API 2.03.09** , exposes both `fmod` and `fmod.studio` APIs to Lua, and gives Defold developers access to FMOD events, banks, buses, VCAs, runtime parameters, low-level audio control, and 3D spatial audio. It also comes with example scenes showing practical use cases like: - 🔊 spatial 3D audio with listener and emitter positioning - 🎛 event playback controls: start, stop, fadeout, pause, resume - 🎚 runtime parameters for things like RPM, pitch, and volume This release also completes the move away from the old bridge layer into a proper Defold native extension setup, with improved build tooling and better platform support. It is supported now across desktop (Windows, Linux, Mac), mobile (Android, iOS), and HTML5. FMOD is a powerful audio solution, and we’re glad to make it easier to use from Defold. If you are already using FMOD, want to try it in a Defold project, or need support for newer FMOD versions, please let us know. * * * The official Defold FMOD extension is now added to the Asset Portal: > **[Defold FMOD](https://defold.com/assets/defold-fmod/)** > > Official Defold native extension for FMOD sound engine bindings.

This is great news. I’ve never used FMOD, but I’ll definitely give it a try! Does anyone know what the impact on file size is for web exports? ---

Thanks for checking! I guess I’ll stay away from it when making web games. All I really needed was a way to change the pitch easily without modifying the speed of the audio. But it’s still nice for desktop and mobile. ---

Hi! Congrats on all the hard work on this! I’m super glad that this still lives on thanks to the awesome Defold team! I know how exciting it was for me to be able to do dynamic music and effects back when I first released it. I hope, now that it’s found a maintainer, more devs will experience that excitement and build cool games with cool sound design. ---

The official FMOD support in Defold is fantastic! I’ve been experimenting with implementing an audio spectrum visualizer using the FMOD extension. I was able to get the RMS (loudness) value through `get_parameter_float` without any issues. However, I couldn’t get the spectrum display working at first, because `get_parameter_data` wasn’t available in the extension. So I asked an AI to help me implement `get_parameter_data`, and with that I was finally able to get the spectrum rendering as shown in the video. [![](https://img.youtube.com/vi/k3iNtwnY7RU/maxresdefault.jpg "FMOD Defold test") ](https://www.youtube.com/watch?v=k3iNtwnY7RU) I’ve also filed an issue about the missing `get_parameter_data` implementation, in case it’s useful for others.
