join two wav files in NAudio before first wav end

Question

I use this function to join two wav files

 public static void Concatenate(string outputFile, ArrayList sourceFiles)
    {
        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);
                    }
                }
            }
        }
        catch (Exception ex)
        { 
        }
        finally
        {
            if (waveFileWriter != null)
            {
                waveFileWriter.Dispose();
            }
        }
    }

But this function join the second wav file after the first wav's end.

What I really want is to join the second wav file 2 milliseconds before the wav's end .

Is there any way to do it using NAudio , or using some other library ?

How are you wanting to join the tracks? Are you looking to mix them or cut 2ms off the second one and paste it to the end? — kidmosey
Hi @zey, i am using the same code as you posted, for me it throws one exception like failed to resolve "System.Runtime.InteropServices.StandardOleMarshalObject". Did you overcome this issue? — Riyas

What you are trying to do, is not a simple join of waves, is a merge. In a merge the waves will be combined to form one "mixed" wave.

To merge files you can follow this documentation of NAudio.

join two wav files in NAudio before first wav end
