HOW TO PLAY SOUND.WAV FILES SIMULTANEOUSLY UNDER EXCEL

[Guest]

I have a requirement to trigger 3 sound effects during execution of an Excel
macro. When the Workbook opens, Function Keys are assigned to each Sound
procedure as follows:

Option Explicit
Private Sub Workbook_Open()

' ASSIGN FUNCTION KEYS

Application.OnKey "{F1}", "Sound1"
Application.OnKey "{F2}", "Sound2"
Application.OnKey "{F3}", "Sound3"

End Sub
Private Sub Workbook_BeforeClose(Cancel As Boolean)

' RESET FUNCTION KEYS

Application.OnKey "{F1}"
Application.OnKey "{F2}"
Application.OnKey "{F3}"

End Sub

The following Windows API function declarations appear in the Module code:

Private Declare Function PlaySound Lib "winmm.dll" _
Alias "PlaySoundA" (ByVal lpszName As String, _
ByVal hModule As Long, ByVal dwFlags As Long) As Long

Private Const SND_ASYNC = &H1
Private Const SND_FILENAME = &H20000

The individual Sound procedures are:

Public Sub Sound1()

Call PlaySound(ThisWorkbook.Path & "\sound1.wav", 0&, SND_ASYNC Or
SND_FILENAME)

End Sub
Private Sub Sound2()

Call PlaySound(ThisWorkbook.Path & "\sound2.wav", 0&, SND_ASYNC Or
SND_FILENAME)

End Sub
Private Sub Sound3()

Call PlaySound(ThisWorkbook.Path & "\sound3.wav", 0&, SND_ASYNC Or
SND_FILENAME)

End Sub

When F1 is pressed, sound1.wav file plays, and similarly when F2 and F3 are
pressed, the corresponding sound2.wav and sound3.wav files play. So far, so
good. If a second sound file is triggered before the first one has finished
playing, the first one is abandoned, and the second plays alone. What I want
is to allow more than one sound file to be triggered and play to completion
without being interrupted.

Is there way of achieving this, perhaps involving a different Windows API
function declaration? Or would 3 Sound Cards be needed to play the wav files
completely independently?

Hi Hotbird,

PlaySound will not play WAV files simultaneously. As you've discovered,
when you start a new sound, any current sounds will stop.

It looks like you may have to use the mcisendstring API call to do this. Do
a search in google, and you'll get lots of results back.

Thanks for this explanation. I have searched Google for MCISendString, and
found examples which allow a WAIT parameter to be specified which ensures
that a playing file is not interrupted. So far, however, I have not seen any
references to multiple wav or midi files playing simultaneously and
independently. Has anyone experience of doing this?

Hmmm...I've never done this, so maybe MCISendString is not the way to go.

The DirectX platform would be much more robust, but it's a lot more complex
than PlaySound.

Here's a link to get you started:

You would have to set a reference in your project to the DirectX 8.0
library.
