Audacity provides a built-in scripting language called Nyquist, which
provides an easy way for users to create their own plug-ins. However I
don't know how suitable it will be for your code as you have not shown
us your code.

Information about Nyquist plug-ins here:
http://wiki.audacityteam.org/wiki/Nyquist_Plug-ins_Reference

If Nyquist is not suitable, then the easiest approach for your own
use, would probably be to copy "Change Pitch" and "Change Tempo" from
the Audacity 2.1.2 source code into the current source code, and
modify them with your algorithm.
(I suggest modifying the 2.1.2 versions rather than the 2.1.3 versions
because the older versions are simpler).
