Summary

Genode.Audio is a simple yet powerful Cross-platform Audio Engine which is provides audio playbacks. Written under C# language based on OpenAL (with OpenTK binding). The main idea is to provide a low-latency audio playback that simple and fast. If you prefer simplicity over fancy features, then this audio engine is for you.

This project has been rewritten to be compatibile with .NET Standard and will no longer supporting initial framework target, which is .NET Framework 2.0

Compiling Project

The project framework is targeted to .NET Standard to ensure maximum compatibility between .NET 4.7 and .NET Core projects. Moreover, this library itself written purely in managed C#, including encoders and decoders but still depend on native dependencies, such as OpenAL. See Dependencies for more details.

It is also required to configure the Build Configuration Platform (x86/x64) of target application to match the library configuration. Avoid using Any CPU platform, because this framework uses native external dependencies (e.g: the engine may fail when deciding which version of openal32.dll to use).

Dependencies

This library uses several dependencies to perform specific operations. The dependencies are separated into 2 types: Internal and External:

• External dependencies are included under Dependencies folder and must be installed or shipped along with the application and located under same folder with the main of application. These dependencies may installed by default in certain Operating System. This folder also used to store Nuget packages (Dependencies/Packages).

• Internal dependencies are compiled along with this library during compilation, the source code is located under Source\Genode.Audio\Dependencies

List of dependencies:

• OpenTK
• NVorbis
• Ogg Vorbis Encoder
