我正在使用nAudio Library来捕获麦克风输入.但我遇到了一个问题.我正在使用nAudio示例应用程序中的代码(我稍微修改过).代码生成基于麦克风输入的WAV文件并将其呈现为波形.这是代码.

private void RenderFile()
{
        SampleAggregator.RaiseRestart();
        using (WaveFileReader reader = new WaveFileReader(this.voiceRecorderState.ActiveFile))
        {
            this.samplesPerSecond = reader.WaveFormat.SampleRate;
            SampleAggregator.NotificationCount = reader.WaveFormat.SampleRate/10;
            //Sample rate is 44100

            byte[] buffer = new byte[1024];
            WaveBuffer waveBuffer = new WaveBuffer(buffer);
            waveBuffer.ByteBufferCount = buffer.Length;
            int bytesRead;
            do
            {
                bytesRead = reader.Read(waveBuffer, 0, buffer.Length);
                int samples = bytesRead / 2;
                double sum = 0;
                for (int sample = 0; sample < samples; sample++)
                {
                    if (bytesRead > 0)
                    {
                        sampleAggregator.Add(waveBuffer.ShortBuffer[sample] / 32768f);
                        double sample1 = waveBuffer.ShortBuffer[sample] / 32768.0; …
