I've got a problem implementing .WAV files in my Delphi program under win
3.11.

I'm trying to make the .WAV file audible by selecting them in a file
listbox and clicking on a button to play them.

I can't get this to work properly...
Does anybody have any experience with this?

If possible I'd like to make the wave files visible in a plot inside a
delphi program...

Send replies via email to Roel.Vankrieki...@ping.be

        Does anybody know where to find a description of the WAV file format?

Don't you guys find it tedious typing the same thing
after your signature each time you post something?
I know I do, but when in Rome...

This is pretty simple.  You need a media player component somewhere on
your form.  You can make it invisible so it doesn't look so ugly.
Anyways, on the DBlClick event handler of the File List box do
something like this:

begin
   MediaPlayer.Filename := FileListBox.Filename;
  MediaPlayer.Play;
end

That's about it.  Hope that works and helps.  Pretty simple to play
CDAudio, Wav, and other standard windows format with the TMediaPlayer
component.

You could also make calls to mmsystem.dll.

Good luck

file format, do you?

Well, I am far behind in reading my mails, but I followed the answers to this
one, and nobody seemed to answer it.
I suggest you look in the SWAG archives. I checked, there is the wav-header (a
couple of times even) simple players etc. All in source.
I don't know where you live, so I cannot try and find a SWAG-support site close
to you.

For those who read this also:
There are a lot of useful things in the SWAG-files. It's full of pascal-sources
and (since last year I thought) also Delphi.

In between the $$$ and $$$ you find some info I saved some time ago.
Let me know if it helped!

Much regards,
Tineke.

Most of this is straight pascal stuff, but some interesting usable
example code to point you in the right direction on things Delphi
can't code for you. Some Delphi stuff in newest update.
