It requires Perl (obviously!), SoX and <a href="../">Ambisuite</a>.

But as the original recordings are not wonderful, publishing an uncompressed version will await a new 'voice' and new recordings.</p> <p>The Perl script will now produce first, second and third-order files (try "-h" for details).</p> <hr /> <p align="right">July 2008 (last updated January 2009).</p> <p align="center"><small>Copyright © 2008-09 Michael Chapman.</small></p> </body> </html>
