The package `github.com/qiniu/audio` is an extensible audio library with simple API for multi platforms in the Go programming language.

## Platforms

* Windows

* macOS

* Linux

* FreeBSD

* Android

* iOS

* Web browsers (Chrome, Firefox, Safari and Edge)

  * GopherJS

  * WebAssembly (Experimental)

## Features

* Pluggable audio decoders. And now it supports the following formats:

  * wav/pcm: `import _ "github.com/qiniu/audio/wav"`

  * wav/adpcm: `import _ "github.com/qiniu/audio/wav/adpcm"`

  * mp3: `import _ "github.com/qiniu/audio/mp3"`

* Audio encoders (TODO).

* Convert decoded audio stream.

## Example

```

import (

	"io"

	"os"

	"github.com/hajimehoshi/oto"

	"github.com/qiniu/audio"

	_ "github.com/qiniu/audio/mp3"

	_ "github.com/qiniu/audio/wav"

	_ "github.com/qiniu/audio/wav/adpcm"

)

func playAudio(file string) error {

	f, err := os.Open(file)

	if err != nil {

		return err

	}

	defer f.Close()

	d, _, err := audio.Decode(f)

	if err != nil {

		return err

	}

	c, err := oto.NewContext(d.SampleRate(), d.Channels(), d.BytesPerSample(), 8192)

	if err != nil {

		return err

	}

	defer c.Close()

	p := c.NewPlayer()

	defer p.Close()

	_, err = io.Copy(p, d)

	return err

}

```
