Playing multiple wav files

Hi,
I need to create a multimedia presentation using Delphi3.
I have tried to play background music and while that is playing, start a wav of a voice but I either get a MIDI error or the voice never gets played. I have tried using 2 Media Player controls to solve this problem. Someone told me that I might have to "stream" the two wave files into the midi player yet I have no idea on how that is to be done.
I basically need source code(commented) that would play two wav files simultaneously. I have Sound Blaster 32Bit. Windows 95. Delphi 3.0.  Please e-mail me the answer in an arj or zip ONLY if it is not larget than 250K if it is, we will discuss some other means of transfer via the web.
Thank you.

Must also show (with source) how I can play avi files that contain sounds as well as background music at the same time.

I'm not sure how aidful my tip would be, but I can tell you how to mix WAV files. There's a microsoft free DLL that does just that. It's called WAVEMIX.DLL and it can play upto 8 mixed WAV files. I have the interface for this dll and I know of a shareware component which fully implemented its usage so you won't have to actually have the .DLL

Tell me if you find this aidful.

If you can tell me (explain) how to actually call the procedures from the DLL that would be great.

Hi MAXcom,

There exists a component which is a translation of the Wavemix DLL. The component is freeware and with source! Believe you needed that? The component can play until 8 wave files simultaneously. Think that's enough, not?
You can find it on this address, but I'll also send a copy of the file to you e-mail address.
