如何使用c＃录制通信器呼叫 [英] How to record a communicator call using c#

问题描述

我想写一个程序来记录通讯器的来电。



我试过很多地方找到这个NAudio大会。但即使这样也无济于事，因为我无法在Naudio中使用环回来初始化音频。



如果有人知道任何替代方案，请帮助，



感谢

Hi,

I want to write a program to record the calls made by the communicator.

I tried many places and find this NAudio Assembly. But even that is not helping since I can''t initialize audioclient using loopback in Naudio.

If any one knows any alternative please help,

Thanks

namespace ConsoleApplication1
{
    class RecordSound
    {
        public void TestSoundCapture()
        {
            MMDeviceEnumerator mEn = new MMDeviceEnumerator();

            MMDeviceCollection deviceCol = mEn.EnumerateAudioEndPoints(DataFlow.Capture, DeviceState.Active);

            Console.WriteLine("All listed Devices are");
            Console.WriteLine("*----------------------*");
            foreach (MMDevice m in mEn.EnumerateAudioEndPoints(DataFlow.All, DeviceState.All))
            {
                Console.WriteLine(m.FriendlyName);
            }

            Console.WriteLine("\nAll active Devices are");
            Console.WriteLine("*----------------------*");
            foreach (MMDevice m in deviceCol)
            {
                Console.WriteLine(m.FriendlyName);
            }

            MMDevice mmDevice = mEn.GetDefaultAudioEndpoint(DataFlow.Capture, Role.Communications);
            Console.WriteLine("\nDefault device is " + mmDevice.FriendlyName.ToString());

            //mmDevice.AudioClient.Start();
            //Console.WriteLine(mmDevice.AudioClient.BufferSize.ToString());
            AudioClient ac = mmDevice.AudioClient;
            
            if (mmDevice.State == DeviceState.Active)
            {
                int x = mmDevice.AudioEndpointVolume.Channels.Count;
                Console.WriteLine(x.ToString());
            }
            WaveFormat wf = ac.MixFormat;


           ac.Initialize(AudioClientShareMode.Shared, AudioClientStreamFlags.Loopback, 10000000, 0, wf, Guid.Empty)
            
            DirectSoundOut dso = new DirectSoundOut();
            WaveIn wavIn = new WaveIn();
            WaveOut wout = new WaveOut();
            WaveMixerStream32 wm = new WaveMixerStream32();
                                                       
            WaveFileWriter WFR = new WaveFileWriter("C://NVIDIA//TEST.WAV", wm.WaveFormat);
            

            Console.ReadLine();
        }

    }
}

以上是我尝试使用Nvideo程序集的代码。我把它标记为粗体（对不起，不知道如何改变颜色，尝试但颜色来自其他位置而不是意图:)）



我想要记录作为Loopback，它会将麦克风和扬声器声音保存在一起。在ac.Initialize方法中，AudioClientStreamFlags.Loopback抛出异常。没有其他值导致任何问题...



谢谢。

Above is the code I tried using Nvideo assembly. I marked it as bold(sorry ,don''t know how to change color ,tried but color comes in other location than intented :))

I want to record as Loopback then it will save both mic and speaker sound together. There in ac.Initialize method AudioClientStreamFlags.Loopback throws exception. No other values cause any issues...

Thanks.
