How do you get mic input?

[MTCMusic]

Hello,
I hope I am posting this in the right section!

I want to create an application that will allow a user to sing into the mic and then give him feedback on his pitch in Hz. This would be part of a singing game to develop good intonation for singing. I think I would use the MCI object, but what commands would I need and how would this work? If anyone has any ideas, I would be very grateful!

Thanks!

Welcome to the forums

This is a rather ambitious thing to start with. I was unaware that the object could record.

I found this: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/_win32_multimedia_command_strings.asp and for recording:

As for recieving the wave length of sounds you need to be able to read wave files

There has been an extension developed by Podunkian that can detect the frequency of a sound, but I don't know if it's actually been released yet.

Thanks for the info, guys! Do you have the link to that extension from Podunkian? Is the MCI object capable of processing audio from the mic?

Thanks

Hey I'm creating a music identifier. A guy named Horn says he knows a guy named Andos who has a freq. detector. You can try contacting him. He had something like what you want I think... Oh and for some reason Podunkian isn't on the User list...

I found the file Andos wrote ond eventualy got it to work on mmf1.5 (sort of) but it's not what you were looking for, or maybe it is.
It uses a dll called "winmm.dll" I'm not to sure of all it's functions.
Andos used it somehow with a overlay to produce and overlay sound over the existing wav.
I seem to remember the overlay use to be in a wav tipe form but nothing shows up on the screen. Acording to the code it sould.

I've just had word back from Podunkian, and he says that it isn't really in a releasable state yet. Andos's might be worth a look.

Do you have that file? I would love to take a look at it. It sounds like it could do the trick. I need to be able to id the frequency and compare it to a value so as to give the user feedback on his pitch accuracy. This would be part of a pedagogic game to develop better intonation in voice students.

Thanks very much for all the replies!

Hmm... I can't load it because I need to download three extensions. Where can I find them?
