First time recording help, another 2 Q's

[Ken Norris]

Howdy,

A couple other questions:

1) What is the most prolific audio filetype for Win/PC machines?

2) How should I pass it in an attachment from my Mac OS 9.2.1 sent to Win/PC
machines?

Also, I'd like it to play automatically when the email opens,  but no luck
so far.
