It'd actually be easier to just use librubberband for frequency shifting

_simple_? well maybe example code that comes with
http://breakfastquay.com/rubberband/

http://www.teuton.org/~gabriel/stretchplayer/ (C++) uses librubberband.
Samplecat's jack_player.c (C) uses LADSPA rubberband and libsamplerate.

The code is not complicated; but probably does not qualify as simple.
