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.
irrKlang
irrKlang is a cross-platform 2D and 3D sound engine and audio library for C++ and .NET development. It plays WAV, OGG, MP3, FLAC, MOD, IT, S3M, and XM files, with both buffered and streamed playback. Its sound capabilities include 3D emulation for low-end hardware, linear or logarithmic rolloff, and effects such as echo, reverb, chorus, and distortion. Developers can use it from C++, C#, VisualBasic.NET, and Delphi.NET. Plugins can extend playback format support, and users can supply their own file readers and decoders. It does not depend on Irrlicht, so it can be used in projects without that engine. irrKlang runs on Windows, Linux, and macOS. It is free for non-commercial products; commercial use requires a Pro license. Listed one-time Pro options start at €65 for individuals and products sold for less than €20, with higher plans for other commercial uses. Linux requires ALSA, and 64-bit systems require matching 64-bit versions. Downloads are available only to existing licensees.
