I have a recorded .wav file.I want to remove the background noise and
separate the speech alone.Is there any c/c++ codes available for achieving
that. So i can integrate in my project.I have downloaded a code from
Audacity but unable to integrate it.Is there is any third party library or
c/c++ code available?Guide me with the right approach to do it?Please help
me out.Thanks.

100% money upfront. This is a limited time offer. The offer can't be
paid with thanks or great appreciations. I reserve the right to kick
your ass. Bla-bla-bla and other restrictions apply.

This can be a lot harder to do in real life than on "CSI: Technology Wet
Dream". Have you tried it with a package like Audacity to see if it's
possible to do, and to do unattended?


I don't know -- it depends on just what you're trying.


Why? Were you unable to find the algorithms, were you unable to get
that part of the code to run by itself, were you unable to understand
what it needed to be fed, what?


See earlier 'dunno'.


Tell us whether you can do the job manually in Audacity, and tell us
which of the tools that Audacity gives works for you. If you're lucky
someone here will be familiar with Audacity and will know the algorithms
used. If not, we'll at least go from the names and bloviate on what
algorithms _might_ be used. Then you can go look for references on the web.

Note that you are likely _not_ going to find code that you can just peel
off the handy paper backing and stick seamlessly into your application
-- even well-written 'pro quality' library code is still going to
require some DSP smarts on your part to fully integrate.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.
