Since writing a custom real-time -audio mixing engine is outside the scope of this project\mref, this section compares -various standalone audio libraries for suitability in the engine. - -\subsection{Libraries} -\label{sec:audio:libs} - -After searching for libraries (search terms: `dynamic/adaptive audio', `real-time -audio', `audio library', `game audio engine'), several libraries were found.
