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.
Elias
Elias 4 is game-audio middleware and a sound engine for interactive soundscapes and adaptive music. Elias Studio gives composers and sound designers visual scripting for sample-perfect audio graphs combining logic, game parameters, playback, and DSP. Its music system supports instrument and track rules, motifs, stingers, automatic loops, random segments, and musical transitions. Spatialized 3D audio and processing such as filters, compressors, and reverbs are included. While a game runs, users can edit patches, replace sound files, and mix without rebuilding or using sound banks. Unity and Godot integrations are provided, and custom or other engines can be integrated. Listed runtime targets include PC, Mac, PlayStation 5, Nintendo Switch, Nintendo Switch 2, iOS, and Android. Elias is written in C and C++, supports Python tooling and automations, and offers source-code access by separate agreement at higher license tiers. Licenses are per game; console releases cost extra per platform, while same-game DLC is covered. Explorer Standard costs €5,850, paid once, and Colonizer Premium costs €15,000, paid once. A free evaluation version is available by request.
