小弟新手，正在研究怎么用C#做个进行录音软件，通过第三方调用DirectX的SoungRecord()已经实现录音功能，但是如何才能够像XP自带的录音机似的能够实时显示录音的数据波形呢？应该用什么控件来做啊？望各位大侠指教，指点一二，或者给个思路也行啊！

private void CreateSoundFile()
        {
            // Open up the wave file for writing.
            mWaveFile = new FileStream(mFileName, FileMode.Create);
            mWriter = new BinaryWriter(mWaveFile);

            // Set up file with RIFF chunk info.
            char[] ChunkRiff = {'R','I','F','F'};
            char[] ChunkType = {'W','A','V','E'};
            char[] ChunkFmt = {'f','m','t',' '};
            char[] ChunkData = {'d','a','t','a'};
         
            short shPad = 1;                // File padding
            int nFormatChunkLength = 0x10;  // Format chunk length.
            int nLength = 0;                // File length, minus first 8 bytes of RIFF description. This will be filled in later.
            short shBytesPerSample = 0;     // Bytes per sample.



            // 一个样本点的字节数目
            if (8 == mWavFormat.BitsPerSample && 1 == mWavFormat.Channels)
                shBytesPerSample = 1;

            else if ((8 == mWavFormat.BitsPerSample && 2 == mWavFormat.Channels) || (16 == mWavFormat.BitsPerSample && 1 == mWavFormat.Channels))
                shBytesPerSample = 2;

            else if (16 == mWavFormat.BitsPerSample && 2 == mWavFormat.Channels)
                shBytesPerSample = 4;

            // RIFF 块
            mWriter.Write(ChunkRiff);
            mWriter.Write(nLength);
            mWriter.Write(ChunkType);

            // WAVE块
            mWriter.Write(ChunkFmt);
            mWriter.Write(nFormatChunkLength);
            mWriter.Write(shPad);
            mWriter.Write(mWavFormat.Channels);
            mWriter.Write(mWavFormat.SamplesPerSecond);
            mWriter.Write(mWavFormat.AverageBytesPerSecond);
            mWriter.Write(shBytesPerSample);
            mWriter.Write(mWavFormat.BitsPerSample);
        
            // 数据块
            mWriter.Write(ChunkData);
            mWriter.Write((int)0);   // The sample length will be written in later.
