RE: Audio Indication of Slide Change

Using http://www.planetpdf.com/planetpdf/pdfs/primer.pdf
We can come to the following working example. The idea is to insert
null dimensional movies and play them when the page is entered. This
does not embed the sounds into the pdf, be warned! I took two files
from my windows media dir to construct the example, but you can take
any file. Notice that Acrobat actually allows for embedding of sounds.

See the example below:
\documentclass[pdf]{prosper}
\makeatletter

\def\PageSound#1{%
  \pdfmark{pdfmark=/ANN,
    Raw={/Rect [0 0 0 0] /Subtype /Movie
    /Title (PageSound) /Movie << /F (#1) >>}%
  }%
  \pdfmark{pdfmark=/PUT,
    Raw={{ThisPage} << /AA << /O << /S /Movie
    /T (PageSound) /Operation /Play >> >> >>}%
  }%
}

\makeatother

\begin{document}

\begin{slide}{Slide 1, no sound}
\end{slide}

\begin{slide}{Slide 2, chord.wav}
\PageSound{chord.wav}
\end{slide}

\begin{slide}{Slide 3, no sound}
\end{slide}

\begin{slide}{Slide 4, chimes.wav}
\PageSound{chimes.wav}
\end{slide}

\end{document}

Best regards,
