Thanks for your suggestion. Is there any literature/article on the working principle of Ogg Vorbis Audio Codec?

</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>
