Omniphony - High performance Spatial Audio Engine with MPV integration

[Glider95]

Omniphony is a high-performance, universal spatial audio engine designed for professional and enthusiast speaker environments. Rather than relying on closed-source hardware, Omniphony handles complex spatial rendering entirely in software.

By pairing Omniphony with an external plugin like harletty-bridge, it can be used to decode TrueHD bitstreams, extract object metadata, and render spatial objects directly to your specific speaker layout using VBAP. The system outputs seamlessly to PipeWire, ASIO, or file—all from a lightweight Rust binary.

Key Technical Highlights:

• Performance: Decodes over 130,000 frames and renders 15 spatial objects to 7.1.4 PCM with 48kHz precision.
• Visual Studio: Includes a 3D interface (Tauri + Three.js) to monitor sound object positioning, speaker heatmaps, and OSC remote control in real time.
• Customization: Supports layouts from 2.0 to 9.1.6, featuring multi-band crossovers, room ratio modeling, and distance attenuation.
• Architecture: A pure-Rust core with a flexible plugin system for adding codecs via .so or .dylib bridges.

Details & Source:

• Platforms: Linux, macOS, Windows
• GitHub: https://github.com/Mgth/Omniphony & and directly integrated with MPV: MPV Omniphony
• License: GPL-3.0

If you are looking for a flexible, commodity-hardware solution for real-time spatial audio rendering, Omniphony provides the framework to build it.

This project is not from me, but from @mgth ! I am just helping to spread the word !

Thanks for the message. And for everyone here: please keep in mind that the software is still at an early stage, although it is already fully functional. Right now, we are mainly focused on distribution, first-install issues, and default configuration. So if you run into any trouble getting it to work, your feedback would be very valuable to us.

I am surprised that this does not pick up more !

I need to correct that the speaker layout is actually customizable to everyone's liking - even to 80.3.56 if you have the budget.
As well, this software is able - with the right bridge - to decode Dolby TrueHD in real-time which I think is a first ever?
