Audio support for Go language

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
}
