You need a comprehensive C/C++ library for implementing spatial audio algorithms including Ambisonics, VBAP, spherical harmonics, HRIR processing, and room simulation.
about
An open-source, cross-platform framework for developing spatial audio algorithms in C/C++. Provides modular components for Ambisonics encoding/decoding, spherical array processing, amplitude panning, HRIR/HRTF processing, room simulation, and other spatial audio techniques. Leverages optimized linear algebra libraries (Intel MKL, Apple Accelerate, OpenBLAS) and x86 SIMD intrinsics for performance.
The framework includes core modules covering higher-order Ambisonics, spherical harmonics, VBAP, the Covariance Domain Framework, HRIR utilities, and reverb algorithms. Optional modules add SOFA file reading, particle-filtering tracking, and HADES binaural rendering. Originally designed for researchers, it has evolved into a substantial codebase with several example implementations realized as VST/LV2 plugins under the SPARTA project.
The modular architecture allows straightforward extension and integration into existing projects via CMake or direct source inclusion. Supports optional Intel IPP for FFT/resampling, FFTW for DFT operations, and NetCDF for large SOFA files.

spaudiopy
Standalone · Engine-agnosticA Python package focused on spatial audio encoders and decoders. Provides implementations of spherical harmonics processing, loudspeaker decoder algorithms including VBAP and AllRAD, and binaural rendering capabilities. Designed for spatial audio research and development workflows requiring programmatic control over encoding and decoding processes. The library offers building blocks for ambisonics workflows, loudspeaker array optimization, and spatial audio format conversion. It integrates with scientific Python ecosystem tools and is particularly suited for prototyping spatial audio systems or analyzing spatial audio signals in research contexts.
libmysofa
Standalonelibmysofa is a C library for reading and processing Head-Related Transfer Function (HRTF) data stored in AES SOFA files conforming to the AES69-2015 standard. It provides functions to load SOFA files, extract HRTF filters for specific spatial coordinates, and convert between Cartesian and spherical coordinate systems. The library handles automatic normalization of HRTF data, nearest-neighbor interpolation for arbitrary listener positions, and efficient caching of multiple SOFA files. It supports both integer and floating-point filter extraction with configurable sample rates and neighbor search parameters. Designed for integration into spatial audio engines and renderers, libmysofa offers both simple and advanced APIs for developers who need direct access to HRTF data without implementing SOFA parsing from scratch.
Resonance Audio
Unity · Wwise · FMOD · StandaloneResonance Audio is a spatial audio SDK that provides HRTF-based binaural rendering, ambisonic encoding/decoding, and room modeling. Originally developed by Google and released as open source, it offers cross-platform support with integrations for Unity, Wwise, FMOD, and VST. The SDK includes tools for geometrical acoustics simulation, reverberation estimation from game geometry, and ambisonic soundfield capture. It supports first-order and higher-order ambisonics, room effects modeling, and binaural rendering using the SADIE HRTF database. The codebase is written in C++ and provides bindings for multiple platforms including desktop, mobile (Android/iOS), and various audio middleware systems. Note: Google archived the GitHub repository in November 2023, so it is no longer actively maintained, though all source code, build scripts, and platform integrations remain available under an open source license.
Godot Steam Audio
GodotA GDExtension that integrates Valve's Steam Audio SDK into Godot 4.4. Provides real-time acoustic simulation including geometric occlusion, sound transmission through surfaces, distance-based attenuation, room reverb via reflections, and spatial ambisonics rendering. Supports dynamic geometry updates. Currently in alpha with working Linux and Windows builds. Includes basic scene setup nodes and runtime effects processing. Planned features include baked reflection maps for performance optimization and expanded raycasting configuration. The extension wraps Steam Audio's Apache-licensed SDK, which is used in production titles like Counter-Strike 2 and Half-Life: Alyx. Intended to provide feature parity with official Unity and Unreal plugins. Note: the author has stated they are no longer actively maintaining the project and welcome community forks.
