## Audio

Audio can be used to narrate content in words, or to demonstrate a scientific concept. Today's scientist are most familiar with audio as the soundtrack to narrated videos that can standalone (as in recordings of talks), or that can accompany content within a paper.  A narrated video example of the latter is discussed below, with reference to "Interacticity."  Less familiar to most scientists today is the process of sonification 
\cite{2012IAUS..285..133D}, where information that may not be inherently auditory such as the power spectrum of the CMB or pulsations from Gamma Ray Burts are encoded into sound streams.  For some, these sonifications can add another channel of data appreciation and formal publishing systems should be prepared to accept audio.
