\begin{frame}{SoundScape Renderer (SSR)}
\begin{itemize}
%\item software tool for \emph{scene-based} realtime spatial audio reproduction
\item several different reproduction methods
\begin{itemize}
\item Binaural Renderer
\item Binaural Room Synthesis (BRS)
\item Wave Field Synthesis (WFS)
\item NFC-HOA Renderer (it's broken, though \dots)
\item Vector Base Amplitude Panning (VBAP)
\item Ambisonic Amplitude Panning (AAP)
\item Generic Renderer
\end{itemize}
\end{itemize}

\pause

\begin{itemize}
\item runs on Linux and macOS (limited support for Windows)
\item uses the \emph{Jack Audio Connection Kit} (JACK)
\item graphical user interface (Qt) and network interface (TCP/IP)
\item Free and Open Source Software (GPLv3)
\item \url{http://spatialaudio.net/ssr/}
\end{itemize}
\end{frame}

\begin{frame}{SSR as a Library}
\begin{itemize}
\item renderers can be easily used in any C++ program
\begin{itemize}
\item with multi-threading
\end{itemize}
\item only audio processing
\begin{itemize}
\item no JACK
\item no GUI
\item no network
\item no scene files
\end{itemize}
\item \dots\ as real-time plugin
\begin{itemize}
\item e.g. PureData external
\end{itemize}
\item \dots\ for offline processing
\begin{itemize}
\item e.g. MEX file for Octave/Matlab
\end{itemize}
\end{itemize}
\end{frame}

\end{frame}

\begin{frame}{Current Limitations, Future Work}
\begin{itemize}
\item extend to 3D
\item dynamic scenes
\item more network interfaces: WebSockets, OSC, \dots?
\item move to browser-based GUI (using WebGL)
\item Python wrapper
\item Pure Data package (Deken)?
\item full Windows port?
\end{itemize}
