audioPlaybackMode | property |
audioPlaybackMode:String| Runtime Versions: | 3 |
Specifies the audio playback mode of all Sound objects. On mobile devices, this property sets sound priorities and defaults according to platform idioms. In desktop and TV environments, no functional difference exists between audio playback modes.
Valid values for this property are defined in the AudioPlaybackMode class.
The default value is AudioPlaybackMode.MEDIA.
Throws
ArgumentError — kInvalidParameterError

bufferTime | property |
bufferTime:int| Runtime Versions: | AIR 1.0, |
The number of seconds to preload an embedded streaming sound into a buffer before it starts to stream. The data in a loaded sound, including its buffer time, cannot be accessed by a SWF file that is in a different domain unless you implement a cross-domain policy file. For more information about security and sound, see the Sound class description.
The SoundMixer.bufferTime property only affects the buffer time
for embedded streaming sounds in a SWF and is independent of dynamically created
Sound objects (that is, Sound objects created in ActionScript).
The value of SoundMixer.bufferTime cannot override
or set the default of the buffer time specified in the SoundLoaderContext object
that is passed to the Sound.load() method.

soundTransform | property |
soundTransform:flash.media:SoundTransform| Runtime Versions: | AIR 1.0, |
The SoundTransform object that controls global sound properties. A SoundTransform object includes properties for setting volume, panning, left speaker assignment, and right speaker assignment. The SoundTransform object used in this property provides final sound settings that are applied to all sounds after any individual sound settings are applied.

useSpeakerphoneForVoice | property |
useSpeakerphoneForVoice:Boolean| Runtime Versions: | 3 |
Toggles the speakerphone when the device is in voice mode. By default, smartphones use the phone earpiece for audio
output when SoundMixer.audioPlaybackMode is set to
AudioPlaybackMode.VOICE. The useSpeakerphoneForVoice property lets you override
the default output so that you can implement a speakerphone button in a phone application. This property
has no effect in modes other than AudioPlaybackMode.VOICE. In desktop and TV environments,
this property has no effect.
Note On Android, you must set the android.permission.MODIFY_AUDIO_SETTINGS
in the AIR application descriptor or changing this value has no effect. In addition, the
setting is global device setting. Other applications running on the device can change
the underlying device setting at any time.
The default value is false.

areSoundsInaccessible | () | method |
public function areSoundsInaccessible():Boolean| Runtime Versions: | AIR 1.0, |
Determines whether any sounds are not accessible due to security restrictions. For example, a sound loaded from a domain other than that of the content calling this method is not accessible if the server for the sound has no URL policy file that grants access to the domain of that domain. The sound can still be loaded and played, but low-level operations, such as getting ID3 metadata for the sound, cannot be performed on inaccessible sounds.
For AIR application content in the application security sandbox, calling this method always
returns false. All sounds, including those loaded from other domains, are accessible
to content in the application security sandbox.
Boolean — The string representation of the boolean.

computeSpectrum | () | method |
public function computeSpectrum(outputArray:ByteArray, FFTMode:Boolean = false, stretchFactor:int = 0):void| Runtime Versions: | AIR 1.0, |
Takes a snapshot of the current sound wave and places it into the specified ByteArray object.
The values are formatted as normalized floating-point values, in the range -1.0 to 1.0.
The ByteArray object passed to the outputArray parameter is overwritten with the new values.
The size of the ByteArray object created is fixed to 512 floating-point values, where the
first 256 values represent the left channel, and the second 256 values represent
the right channel.
Note: This method is subject to local file security restrictions and restrictions on cross-domain loading. If you are working with local files or sounds loaded from a server in a different domain than the calling content, you might need to address sandbox restrictions through a cross-domain policy file. For more information, see the Sound class description. In addition, this method cannot be used to extract data from RTMP streams, even when it is called by content that reside in the same domain as the RTMP server.
This method is supported over RTMP in Flash Player 9.0.115.0
and later and in Adobe AIR. You can control access to streams on
Flash Media Server in a server-side script. For more information, see the Client.audioSampleAccess
and Client.videoSampleAccess properties in
Server-Side ActionScript Language Reference for Adobe Flash Media Server.
Parameters
outputArray:ByteArray — A ByteArray object that holds the values associated with the sound.
If any sounds are not available due to security restrictions
(areSoundsInaccessible == true), the outputArray object
is left unchanged. If all sounds are stopped, the outputArray object is
filled with zeros.
| |
FFTMode:Boolean (default = false)true causes the method to return a
frequency spectrum instead of the raw sound wave. In the frequency spectrum, low frequencies
are represented on the left and high frequencies are on the right.

stretchFactor:int (default = 0)stretchFactor value to 0, data is sampled at 44.1 KHz;
with a value of 1, data is sampled at 22.05 KHz; with a value of 2, data is sampled 11.025 KHz;
and so on.

stopAll | () | method |
public function stopAll():void| Runtime Versions: | AIR 1.0, |
Stops all sounds currently playing.
>In Flash Professional, this method does not stop the playhead. Sounds set to stream will resume playing as the playhead moves over the frames in which they are located.
