Client-Side Communication ActionScript 49

Returns

Nothing.

Description

Method; sets the rate, in kHz, at which the microphone should capture sound.

Example

The following example sets the microphone rate to the user’s preference (which you have assigned

to the

userRate variable) if it is one of the following values: 5, 8, 11, 22, or 44. If it is not, the

value is rounded to the nearest acceptable value that the sound capture device supports.

myMic.setRate(userRate);

See also

Microphone.rate

Microphone.setSilenceLevel

Availability

• Flash Player 6.

• Flash Communication Server MX (not required).

Usage

activeMicrophone.setSilenceLevel(level [, timeout])

Parameters

level An integer that specifies the amount of sound required to activate the microphone and

invoke

Microphone.onActivity(true). Acceptable values range from 0 to 100. The default

value is 10.

timeout An optional integer parameter that specifies how many milliseconds must elapse

without activity before Flash considers sound to have stopped and invokes

Microphone.onActivity(false). The default value is 2000 (2 seconds).

Returns

Nothing.

Description

Method; sets the minimum input level that should be considered sound and (optionally) the

amount of silent time signifying that silence has actually begun.

• To prevent the microphone from detecting sound at all, pass a value of 100 for level;

Microphone.onActivity is never invoked.

• To determine the amount of sound the microphone is currently detecting, use

Microphone.activityLevel.

Activity detection is the ability to detect when audio levels suggest that a person is talking. When

someone is not talking, bandwidth can be saved because there is no need to send the associated

audio stream. This information can also be used for visual feedback so that users know they (or

others) are silent.
