AeonWave-HD 64

AeonWave-HD 64 is a GPL licensed, 3D and 4D audio library aimed at the professional audio, multimedia, game, simulation and virtual-reality market supporting Windows 7, Windows 8, Windows 10 and Linux operating systems (Intel and ARM). The software renders audio considerably faster than competing products.

Highlights

The software provides a small, easy to use, fault tolerant and consistent API for the C language. In addition there is an even easier to use C++ API which exposes all the advantages C++ has to offer. The C++ API also comes with a buffer cache to minimize resources, and a simple way to stream background music without the need for the calling program to fill audio buffers on demand. This is done using the integrated audio streaming code which can also be used to read sound buffers, even from a remote location.

The library provides low latency support by taking optimal advantage of the users hardware. It, for instance, uses automatic load balancing threading when required and available (up top 16-cores can be utilized).

There is simultaneous support for stereo and 3D/4D audio. Stereo support is useful for audio mixing and synthesizer applications while 3D/4D audio support is targeted at simulation and augmented reality solutions.
AeonWave supports distance time delay if you need it, but only if you want it.

Another thing that sets AeonWave apart is support for audio-frames with sub-mixing capabilities and 3D/4D emitter/audio-frame grouping support. Moving or rotating an audio-frame automatically reorientates all registered emitters and audio-frames along with it. There is no need to orientate them one by one. Audio-frames also adds the posibilty to set filters or effects to a group of emitters: If an object with multiple sound emitters moves behind a building or a structure then a single frequency filter assigned to its audio-frame is sufficient.

Buffers play a crucial role when using AeonWave. At first they were designed to store audio data which could be played back anywhere in the scene by attaching them to emitters. Later on support was added to reconstruct sounds by synthesizing them using basic waveform shapes and adding, mixing or ringmodulating them. This can dramatically reduce the package size since sounds (like for instance a hazard alarm or telephone ring) don't need to be shipped as audio files anymore. In the latest code buffers are also used to set filters and effects. Now (almost) all of the sound expericence can be taken out of the hands of the developer and into the hands of the sound effects specialist.
AeonWave is designed for ease of development.

AeonWaves way of defining all sound properties is using filters and effects. Almost anything can be controlled either by a filter or by an effect: ranging from pitch settings, envelope shape, frequency filter to distance attenuation. New in version 3.0 is the option to define filters and effects for any object (mixer, audio-frames or emitters) using AAXS encoded buffers. This results in smaller, and easier to read, code. AAXS files can be retrieved using the sound streaming code provided by the library. This makes it is possible to store them on a remote host allowing you to tweak sound properties for already installed software without the need to recompile, and reinstall the software.
The only equirement is an internet connection.
