I don't know if any BCB specific books, but there is a Delphi multimedia 
programming book that covers audio programming (not MCI) so you have 
access to the sound buffers directly.  From there you should be able to 
apply the same filter routines that are in the VC source code.

Since it is all WinAPI you could probably cut and paste the VC functions 
into BCB and get them to work with little effort.

Don't forget (like I just did) that there is a chapter in Petzold on 
audio programming.  It basically covers recording WaveForms with Win32 
API and would probably be a bit more straight forward that trying to 
convert the delphi code.

If you don't have Petzold, then try looking up waveInStart in either the 
win32 help, or msdn.microsoft.com.  That should get you started.

Good enough, thank you!
I am sorry - it's _BCB_ :)

I actually have a book called Digital Audio Processing by Doug Coulter. It
has loads of code that comes on CD with it, all VC++, of course. I also just
found a fine-working complete code for a multi-band EQ. DSP code does not
grow on trees so that's a real find. This stuff is not trivial, so some
help-by-example helps a lot. My knowledge of OOP is limping too, so I am in
for some sweatin'  ;)

Hi,
just some thoughts....

I am also doing DSP like things with BCB, mostly working with wave files.
Currently I'm working with DirectX/DirectSound and it took me a while to
setup DirectSound in BCB.
If you only want to use the Multimedia API it should be easier.

However, there is one thing that makes me stick with BCB:
Once I set up my backend DSP routines so that they compile in BCB I want to
test them with some GUI (trackbars, buttons or edits, showing the results of
changes). And this is where I think BCB saves you a lot of coding! You can
always redesign your GUI in minutes!!

Also I think that DSP routines (even from a VC++ book) should not depend too
much on VC++, so it's maybe not that difficult to use them in BCB. As Mathew
said, as long your code is plain WinAPI it should always work in BCB without
problems.

If you need any source code maybe specify one of your VC++ examples and I
will see what I can do...

Hey, guys, I appreciate the help. Right now I am in the very early stage,
just looking around :)
My sticking with BCB is for the same exact reason - ease of GUI design is a
joy with Borland products.
My case is a bit better since I am not designing a wave editor - all DSP
functions will be under the hood with one-time tweaked settings, that's the
kind of thing I am doing.
I am a die-hard Borland fan, so screw MFC! Life is short! :)
