.WAV joiner

A little time ago, I needed to join .wavs together. I couldn't find a simple solution on the internet so i decided to create one. Credit to Inferrd for helping me out. Anyway, the code is below and it is very simple. The .wav files are in resources in the example but they could be anywhere you like. The magic happens in the sub Join() and it plays the concatenated sound to prove it works. All you need is a form with a button called Button2.

vb.net Code:

Public Class Form1
 
    Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
        Dim wav1 As List(Of Byte) = IO.File.ReadAllBytes("h.wav").ToList
        Dim wav2 As List(Of Byte) = IO.File.ReadAllBytes("e.wav").ToList
 
        wav1 = Join(wav1, wav2)
        wav1 = Join(wav1, IO.File.ReadAllBytes("l.wav").ToList)
        wav1 = Join(wav1, IO.File.ReadAllBytes("ow.wav").ToList)
 
        Using ms As New System.IO.MemoryStream(wav1.ToArray)
            Using snd As New System.Media.SoundPlayer(ms)
                snd.Play()
            End Using
        End Using
    End Sub
 
Private Function Join(ByVal wavBytes As List(Of Byte), ByVal wav2 As List(Of Byte)) As List(Of Byte)
 
        '   add on the second file excluding its header bytes
        wavBytes.AddRange(wav2.Skip(44).Take(wav2.Count - 44))
 
 
        '   rewrite the ChunkSize and Subchunk2Size fields of the Header
        Dim chunkSize As Integer = wavBytes.Count - 8
        Dim subChunk2Size As Integer = wavBytes.Count - 44
 
        Dim chunkSizeBytes() As Byte = BitConverter.GetBytes(chunkSize)
        Dim subChunk2SizeBytes() As Byte = BitConverter.GetBytes(subChunk2Size)
        For i = 0 To 3
            wavBytes(4 + i) = chunkSizeBytes(i)
            wavBytes(40 + i) = subChunk2SizeBytes(i)
        Next
 
        Return wavBytes
    End Function
 
    ' <summary>
    ' Function to save byte array to a file
    ' </summary>
    ' <param name="_FileName">File name to save byte array</param>
    ' <param name="_ByteArray">Byte array to save to external file</param>
    ' <returns>Return true if byte array save successfully, if not return false</returns>
    Public Sub ByteArrayToFile(ByVal _FileName As String, ByVal _ByteArray() As Byte)
        If System.IO.File.Exists("temp.wav") = True Then
            System.IO.File.Delete("temp.wav")
        End If
        Try
            ' Open file for reading
            Dim _FileStream As New System.IO.FileStream(_FileName, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write)
            ' Writes a block of bytes to this stream using data from a byte array.
            _FileStream.Write(_ByteArray, 0, _ByteArray.Length)
            ' close file stream
            _FileStream.Close()
 
        Catch _Exception As Exception
            ' Error
            Console.WriteLine("Exception caught in process: {0}", _Exception.ToString())
        End Try
 
    End Sub
End Class
