快速入门：使用Go语言函数实现简单的音频处理功能

go get github.com/go-audio/audio

func readAudioFile(path string) (*audio.File, error) {
    file, err := os.Open(path)
    if err != nil {

    defer file.Close()

    dec := wav.NewDecoder(file)

    // Read the audio file

    if err := dec.Read(buff); err != nil {
        return nil, err

        NumChannels: dec.NumChannels,
        Data:        buff,
    }

    return audioFile, nil
}

func processAudio(audioFile *audio.File) {
    // 在这里实现你的音频处理逻辑
    // 例如调整音频音量、应用均衡器等

    // 打印处理完成的音频信息
    fmt.Println("Audio processing complete")
    fmt.Println("Sample Rate:", audioFile.SampleRate)
    fmt.Println("Num Channels:", audioFile.NumChannels)
}

    // 读取音频文件
    audioFile, err := readAudioFile("path/to/audio/file.wav")
    if err != nil {
        panic(err)
    }

    // 处理音频文件
    processAudio(audioFile)
