Get pitch of live audio input?

[emdalton]

I would like to use the pitch of audio input through a built-in mic or audio in jack in my app. I see how to record sound, but is there a way to work with the live input sound directly? If possible, I'd like to be able to do this across platforms. If it would require externals, I'd be interested in negotiating with someone to develop them.

Thanks in advance for any help....

A Google search turned up this thread from 2008:

I may be stuck having to use an external, unless something has changed since then. This would be problematic as I'd like to have it work across multiple platforms....

On the other hand, here's a library that might have the functionality I need, but I have no idea how to make it into an external:

Another edit: I found a thread at the un4seen site that makes me think this library can do what I want, and it is available for windows, osx, iOS, and Android. I'm not sure how externals work with the web plugin. The licensing cost is not trivial, but not outrageous. So now I need to find someone to write an external, I guess... and figure out how to square the licensing with Un4seen.

Un4seen responded today saying I can use the "shareware" license to cover my external, though if anyone else wants to use the external they'll need to get their own license. Now I just need to figure out how to make the external itself... or get someone to help.

Elizabeth,

can you show me how you record audio? I need to record to MP3 files and save them.

Thanks,

Warren
