c# - 如何用 C# 和 NAudio 覆盖两个 wav 文件？

Question

我正在使用 NAudio 库来处理音频文件。我想要做的是将多个音频放在一起并从起点将它们组合起来。如果需要用图来说明；

A.wav
|-------------------------|
B.wav
|---------------|

我为这个过程写了下面的代码，但是这段代码以下面的方式组合了声音；

A.wav |--------------------| B.wav |--------------|

这是代码块；

public static void Concatenate(string outputFile, IEnumerable<string> sourceFiles)
        {
            outputFile = Path.Combine(@"C:\Users\umutg\OneDrive\Masaüstü\Muesyco\Combined\" + outputFile);

            byte[] buffer = new byte[1024];
            WaveFileWriter waveFileWriter = null;

            try
            {
                foreach (string sourceFile in sourceFiles)
                {
                    using (WaveFileReader reader = new WaveFileReader(sourceFile))
                    {
                        if (waveFileWriter == null)
                        {
                            // first time in create new Writer
                            waveFileWriter = new WaveFileWriter(outputFile, reader.WaveFormat);
                        }
                        else
                        {
                            if (!reader.WaveFormat.Equals(waveFileWriter.WaveFormat))
                            {
                                throw new InvalidOperationException("Can't concatenate WAV Files that don't share the same format");
                            }
                        }

                        int read;
                        while ((read = reader.Read(buffer, 0, buffer.Length)) > 0)
                        {
                            waveFileWriter.WriteData(buffer, 0, read);
                        }
                    }
                }
            }
            finally
            {
                if (waveFileWriter != null)
                {
                    waveFileWriter.Dispose();
                }
            }

        }

public static string CreateMashup(List<string> files, string filename)
{
    List<AudioFileReader> mixList = new List<AudioFileReader>();
    // because there is no mash up with less than 2 files
    if (files.Count() < 2)
    {
        throw new Exception("Not enough files selected!");
    }

    try
    {
        var mixer = new WaveMixerStream32
        {
            AutoStop = true
        };

        var outputFile = Path.Combine(@"C:\Users\umutg\OneDrive\Masaüstü\Muesyco\Combined\" + filename);

        {
            var filePath = Path.Combine(@"C:\Users\umutg\OneDrive\Masaüstü\Muesyco\Download\" + file);
