推荐答案

下面是为我工作的代码：

Here is the code that worked for me:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using NAudio.Wave;
using NAudio.CoreAudioApi;

namespace WindowsFormsApplication1
{
    public partial class Form4 : Form
    {

        private BufferedWaveProvider bwp;

        WaveIn wi;
        WaveOut wo;
        public Form4()
        {
            InitializeComponent();
            wo = new WaveOut();
            wi = new WaveIn();

            wi.DataAvailable += new EventHandler<WaveInEventArgs>(wi_DataAvailable);

            bwp = new BufferedWaveProvider(wi.WaveFormat);
            bwp.DiscardOnBufferOverflow = true;

            wo.Init(bwp);
            wi.StartRecording();
            wo.Play();

        }

        void wi_DataAvailable(object sender, WaveInEventArgs e)
        {
            bwp.AddSamples(e.Buffer, 0, e.BytesRecorded);

        }
    }
}
