Check if a MIME Part is Audio

Demonstrates the Chilkat Mime.IsAudio method, which returns whether the Content-Type begins with audio/. It takes no arguments and applies to the current part.

Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own file.

Background: Useful for classifying media attachments — a voicemail or audio note in a message, for example — so it can be routed to a player or handled distinctly from other content. It matches any audio/ subtype.
