C＃一次播放一个扬声器的声音

Question

我试图一次从一个扬声器/耳机播放声音。所以我将一方的值归零。但它不起作用。 在一个wav文件中，偶数值来自右扬声器/听筒和右起扬声器？ 那么为什么它不起作用

这是我的代码：

    public override int Read(byte[] buffer, int offset, int sampleCount)
    {
        if (position == 0 && onetimeflag == false)
        {
            n2 = 0;
            onetimeflag = true;
        }
        if (n2 >= Bufferlength && stopflag == false)
        {
            Dispose();
            return 0;
        }

        float temp1;
        for (int i = 0; i < (sampleCount / 4); i++)
        {
            if (Frequency_switch == true)
            {
                temp1 = (float)(Amplitude * Math.Sin(Math.PI * Frequency * n2 / 44100D));
                Frequency_switch = false;
            }
            else
            {

                temp1 = (float)(Amplitude2 * Math.Sin((Math.PI * Frequency2 * n2) / 44100D));
                Frequency_switch = true;
            }
            byte[] bytes = BitConverter.GetBytes(temp1);
            buffer[i * 4 + 0] = bytes[0];
            buffer[i * 4 + 1] = bytes[1];
            buffer[i * 4 + 2] = bytes[2];
            buffer[i * 4 + 3] = bytes[3];

            tempSample++;
            n2++;
        }
        return sampleCount;}} }

我正在使用NAudio库

这是我播放声音的方式：

private void button1_Click(object sender, EventArgs e)
    {
        Play(1, 240, 0);
    }
    binaural_beats BBeats;
    WaveOut waveout;
    void Play(double Amp, double Left, double Right)
    {
        BBeats = new binaural_beats();
        BBeats.Amplitude = Amp;
        BBeats.Amplitude2 = Amp;
        BBeats.Frequency = Left;
        BBeats.Frequency2 = Right;

        BBeats.Bufferlength = 44100 * 2 * 3;// will play for 3 sec

        waveout = new WaveOut();
        WaveChannel32 temp = new WaveChannel32(BBeats);
        temp.PadWithZeroes = false;

        waveout.Init(temp);
        waveout.Play();

    }
