# SharpAudio

SharpAudio is a cross-platform, backend-agnostic library to playback sounds in .NET. It achieves that by wrapping the platform specific backends.

Supported backends:

- XAudio2

- OpenAL

# Build status

![Build Status](https://github.com/feliwir/SharpAudio/workflows/CI/badge.svg?branch=master&event=push)

![Nuget](https://img.shields.io/nuget/v/SharpAudio)

# Example

SharpAudio provides a low-level interface that wraps audio sources & buffers:

```csharp

    var engine = AudioEngine.CreateDefault();

    var buffer = engine.CreateBuffer();

    var source = engine.CreateSource();

    // Play a 1s long sound at 440hz

    AudioFormat format;

    format.BitsPerSample = 16;

    format.Channels = 1;

    format.SampleRate = 44100;

    float freq = 440.0f;

    var size = format.SampleRate;

    var samples = new short[size];

    for (int i = 0; i < size; i++)

    {

        samples[i] = (short)(32760 * Math.Sin((2 * Math.PI * freq) / size * i));

    }

    buffer.BufferData(samples, format);

    source.QueueBuffer(buffer);

    source.Play();

```

A high level interface that can load and play sound files is provided in the SharpAudio.Codec package:

```csharp

    var engine = AudioEngine.CreateDefault();

    var soundStream = new SoundStream(File.OpenRead("test.mp3"), engine);

    soundStream.Volume = 0.5f;

    soundStream.Play();

```

The following sound formats are supported at the moment:

- `.wav` (PCM & ADPCM)

- `.mp3` 

- `.ogg` (WIP: Vorbis & Opus)
