In their own words
Amplitude Audio SDK
Amplitude Audio SDK is a cross-platform audio engine for games, supporting audio for 2D, 3D, and VR/AR environments. It runs on Android, iOS, Linux, macOS, and Windows; Windows, Linux, and macOS are listed as runtime platforms. Project assets are defined in JSON and compiled into binary sound banks for runtime loading. Audio options include stereo panning, binaural rendering with user HRTF assets, and Ambisonic rendering. Developers can configure processing per runtime platform, including filters, room effects, and spatialization, and extend the pipeline with plugins. A MiniAudio-based default driver and MP3 and WAV decoding are included. Official integrations are listed for O3DE, ezEngine, Godot 4+, and Flax Engine. The SDK is free and open source under Apache-2.0, but it is in beta without an official release; nightly builds are for development, not production. Amplitude Studio is in early access with complimentary access during that phase; its planned free version has non-commercial and feature limits.
