Concatenating Wav files

[pjwraith]

I have recently started playing with .net for its usefulness in performing functions for an application I use.

I am in need of an ability to join 2 wav files to produce a third singular wav file which contains the other two files added together. Ideally I would like to be able to join more than two but I can always repeat the function.

Does anyone know of a method of performing this action ?

Thanks in advance

I suppose you could read both files in a stream and then save it. Don't ask me how, just something to look into.

What Chrissie is suggesting should be possible. Im not familiar with the .WAV format, but it appears to have no end of file marker, so it should just be a case of adding the Data Blocks together. You'll need to google WAV File Format to find more info on the format type of the file.
To read a file from a stream

Public Function zGetFileasByteArray(ByVal sFileName As String) As Byte()

Dim fs As FileStream = New FileStream(sFileName, FileMode.Open, FileAccess.Read)
Dim b() As Byte = New Byte(CInt(fs.Length)) {}
fs.Read(b, 0, CInt(fs.Length))
fs.Close()

Return b

End Function

The wav header specifies channels, average bps, sample rate and some more.
So to make a good concatination you will need to make sure those settings are the same, and then remeber to strip the header from the second file.
As SqueakinSweep said.. some googling on the wav format should be done
