The Microphone Class

Name	Format	Description
`get`	`Microphone.get([` `index` `])`	Returns a default or specified audio stream, or `null` if no microphone is available.
`setGain`	`myMicrophone.setGain(` `gain` `)`	Specifies the amount by which the microphone should boost the signal, from to `100` .
`setRate`	`myMicrophone.setRate(` `kHz` `)`	Specifies the rate at which the microphone should capture sound, in kHz.
`setSilenceLevel`	`myMicrophone.setSilenceLevel(` `level` `[,` `timeout` `])`	Specifies the sound level (from to `100` ) required to activate the microphone. Optionally also sets `timeout` , specifying milliseconds of inactivity before Flash invokes `Microphone.onActivity(false)` . The default value is `2000` (2 seconds). The default value of `level` is `10` .
`setUseEchoSuppression`	`myMicrophone.setUseEchoSuppression (` `suppress` `)`	`suppress` is a Boolean that specifies whether to use the echo suppression feature of the audio codec.

Format	Description
`myMicrophone.activityLevel`	The amount of sound the microphone detects, from to `100` .
`myMicrophone.gain`	The amount by which the microphone boosts the signal before transmitting it, from to `100` . The default is `50` .
`myMicrophone.index`	The index of the current microphone.
`myMicrophone.muted`	A Boolean value that specifies whether the user has allowed or denied access to the microphone.
`myMicrophone.name`	The name of the current sound capture device, as returned by the sound capture hardware.
`Microphone. names`	A class property, an array of strings containing the names of all available sound capture devices, including sound cards and microphones.
`myMicrophone.rate`	The sound capture rate, in kHz.

Name	Format	Description
`onActivity`	`myMicrophone.onActivity = function (` `activity` `){ }`	Invoked when the microphone starts or stops detecting sound. `activity` is a Boolean value set to `true` when the microphone starts detecting sound, and `false` when it stops.
`onStatus`	`myMicrophone.onStatus = function (` `infoObject` `){}`	Invoked when the user allows or denies access to the microphone. `infoObject` usage similar to that of `Camera.onStatus` .
