Using the Speech compression option

The speech compression option exports sounds using a compression specially adapted to speech.

 
To use speech compression:

1

In the Sound Properties dialog box, choose Speech from the Compression menu.

2

For Sample Rate, select an option to control sound fidelity and file size. A lower rate decreases file size but can also degrade sound quality. Choose from the following options:

5 kHz is acceptable for speech.

11 kHz is recommended for speech.

22 kHz is acceptable for most types of music on the Web.

44 kHz is the standard CD audio rate. However, since compression is applied, the sound will not be of CD quality in the Flash movie.
