+\begin{block}{We just need a python library to:}
+
+ \begin{itemize}
+
+ \item \alert{Do} asynchronous and fast audio processing with Python,
+ \item \alert{Decode} audio frames from ANY format into numpy arrays,
+ \item \alert{Analyze} audio content with some state-of-the-art audio feature extraction libraries,
+ \item \alert{Organize}, serialize and save analysis metadata through various formats,
+ \item \alert{Draw} various fancy waveforms, spectrograms and other cool graphers,
+ \item \alert{Transcode} audio data in various media formats and stream them through web apps,
+ \item \alert{Playback} and \alert{interact} on demand through a smart high-level HTML5 extensible player,
+ \item \alert{Index}, \alert{tag} and \alert{organize semantic metadata} (see \href{http://telemeta.org/}{Telemeta} which embeds TimeSide).
