About

This project is a cross-platform .NET Core/Standard 3D audio engine based on OpenAL.

---

Features

---

• Based on the OpenAL 1.1 specification
• Multiple output and sound capture devices
• Full 3D sound support with different distance models, pitch shifting and other stuff
• Bundled with PCM WAV, OGG and MP3 importers (thanks to NLayer and NVorbis)

Examples

---

For runnable examples check out the Samples directory.

Simple audio playback

var outputDevice = new OutputDevice();
...
var buffer = Wav.Load("never_gonna_give_you_up.wav");
...
var source = new SoundSource();
source.Enqueue(buffer);
source.Play();

Microphone capture

var inputDevice = new CaptureDevice();
...
inputDevice.StartCapture();
...
var samples = new byte[0];
// If you're running it in a game loop, you don't need a while loop here
// Just allocate a big enough buffer and reuse it
while (something)
{
    inputDevice.ProcessSamples((data, bytesRead) =>
    {
        var oldSize = samples.Length;
        Array.Resize(ref samples, oldSize + bytesRead);
        Array.Copy(data, 0, samples, oldSize, bytesRead);
    });
    Thread.Sleep(100);
}
...
inputDevice.StopCapture();
...
// Do something with the samples array
// Put the data from it in a SoundBuffer, for example
