Microphone (object)

Availability

• Flash Player 6.

• Flash Communication Server MX (not required).

The Microphone object lets you capture audio from a microphone attached to the computer that

is running the Macromedia Flash Player. When used with Flash Communication Server, this

object lets you transmit, play, and optionally record the audio being captured. With these

capabilities, you can develop communications applications such as instant messaging with audio,

recording presentations so others can replay them at a later date, and so on. (Flash provides

similar video capabilities; for more information, see the “Camera (object)” entry.)

You can also use a Microphone object without a server—for example, to transmit sound from

your microphone through the speakers on your local system.

To create or reference a Microphone object, use

Microphone.get.
