Wavemix32.dll VDS 5.x Interface :

What is WaveMix :
-----------------
The WaveMix DLL is a utility that allows multiple WAV files to be played simultaneously. It is designed to be as simple to use as possible but still have the power to do what is required by games. The DLL supports 8 channels of simultaneous wave play, the ability to queue up waves along the same channel and wave completion notification.

WaveMix uses the standard sound drivers, it is not dependent of special drivers. The advantage is that it works directly with any version of Windows, starting from 3.1 and with virtually any sound card.

Why WaveMix at all now that DirectSound exists? For simple programs that need simple sound mixing (without strict low-latency requirements), WaveMix works fairly well and it is simple to install with the program.

Wavemix in VDS 5.x
------------------
I have made a script that calls this dll from VDS 5.x
This provides multichannel sound capabilities to VDS programmers especially those who write games in VDS.
It also helps for those who need mixing of different sounds for other purposes and with suitable additions to the code these mixed sounds can be recorded to a wave file !!!

The included code plays 8 channels simultaneously at 22KHz.
I have kept it at that for compatibility with most computers.
If you want a better performance change it to 44KHz in the ini file.
The version of the dll (1.80) included doesn't require you to install the dll in system directory - You have to place it in the app directory.

I have also written a dll to help calculate hiword and loword values. You can do without it and calculate using the code commented in the dsc (thanks to mindpower). However this may be a little slower, a difference that may be noticed in games etc.

I hope this helps VDS programmers.

Using Advanced options:
-----------------------
There are several advanced options available which are intentionally omitted from the source code(dsc) file to keep it simple.
If you want to use them see the attached documentation (eg You can change the volume of individual channels close a channel silence a channel and so on).

Copyrights:
------------
All the included documentation codes and the Wavemix dll are copyright of their respective owners including Microsoft Corporation.
You are free to distribute this source code unaltered as well as modify and compile it as long as you include the relevant copyright information AND the conditions of the included component owners don't prevent you.(As far as I know there is no restrictions on distribution)

Disclaimer:
----------
As with calling any non VDS dll you do it at your own risk. I advise you to save your work before running /debugging it to safeguard your data. The dll is known to crash VDS IDE during unload. You may compile and test it to avoid this.
This compilation is not declared to be fit for any purpose whatsoever.

You can download the source code with complete help and required dlls at:

CodeScript, maybe it is easier for other people to make includable code. That way people who don't understand the sourcecode, can still use it... Just a thought... Wink

I have never written include scripts but I think it should be easier than the script i wrote Smile.
Also do U think that the script/or others in this section are very difficult to follow ? I always try to simplify things by commenting as much as possible.
I am busy now but will try writing one.
In the meanwhile if U want U R welcome to can write one.

BTW does the dll work fine or does it give scratchy sounds and needs configuring. I was just wondering.

Regards

It works very well on my system playing sounds and playing them simultaneously. However, I get
an "error loading library" when exiting the sample program, line 256:

Code:
%Z = @lib(WAVEMIX32,WaveMixCloseChannel,INT:,%I,7,1)


Hasta la vista, baby!

I think you R on Win 9x. In win 2k it crashes the IDE badly on exit. So it is advisable to compile and run it. I think it is a bug in the dll. It sometimes crashes VB IDE too on exit. I have tried some small workaround. The updated package may not crash the IDE on exit even on XP.

Additional info:
I have updated the package
Stereo sound has been enabled.
Better Sound quality.
Detailed step by step help file has been added !.
DLL configuration utility added.
Some small bug fixes.

Please note that I have not updated the above script posted here as it may take hours Sad on my slow dialup.

Nope, I'm on XP...

But, never mind. With your changes, it now works just fine! No problems so far.
