Hi All,<br><br> I see the source codes mdct.c; lpc.c; smallft.c use floats. How do I modify them to run on a fixed point Processor, with no float functionality? Is there an integer implementation of Ogg Vorbis Codec?<br>

</div>The best place to start for such optimizations is generally to profile<br>
the established code on your device. Then you can start optimizing the<br>
portions which take the most time.<br>
