Microphone.rate
Availability
Flash Player 6.
Usage
activeMicrophone.rate
Description
Read-only property; the rate at which the microphone is capturing sound, in kHz. The default
value is 8 kHz if your sound capture device supports this value. Otherwise, the default value is the
next available capture level above 8 kHz that your sound capture device supports, usually 11 kHz.
To set this value, use
Microphone.setRate().
Example
The following example saves the current rate to the variable original.
original = myMic.rate;

Microphone.setGain()
Availability
Flash Player 6.
Usage
activeMicrophone.setGain(gain)
Parameters
gain
An integer that specifies the amount by which the microphone should boost the signal.
Valid values are 0 to 100. The default value is 50; however, the user may change this value in the
Flash Player Microphone Settings panel.
Returns
Nothing.
Description
Method; sets the microphone gain—that is, the amount by which the microphone should
multiply the signal before transmitting it. A value of 0 tells Flash to multiply by 0; that is, the
microphone transmits no sound.
You can think of this setting like a volume knob on a stereo: 0 is no volume and 50 is normal
volume; numbers below 50 specify lower than normal volume, while numbers above 50 specify
higher than normal volume.
Example
The following example ensures that the microphone gain setting is less than or equal to 55.
