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.

The SoundTransform object that controls global sound properties. A SoundTransform object includes properties for setting volume, panning, left speaker assignment, and right speaker assignment. This SoundTransform object only affects sounds embedded within a SWF file. The SoundTransform object used in this property provides final sound settings that are applied to all sounds after any individual sound settings are applied.

Determines whether any sounds are not accessible due to security restrictions. For example, a sound loaded from a domain other than that of the SWF file is not accessible if the server for the sound has no cross-domain policy file that grants access to the domain of the SWF file. 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.

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 SWF files or sounds loaded from a server in a different domain than the calling SWF, 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 SWF files that reside in the same domain as the RTMP server.

Stops all sounds currently playing.

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.

When using this property, consider the Flash Player security model:

• By default, calling the soundMixer.stopAll() method stops only sounds in the same security sandbox as the object that is calling the method. Any sounds whose playback was not started from the same sandbox as the calling object are not stopped.
• When you load the sound, using the load() method of the Sound class, you can specify a context parameter, which is a SoundLoaderContext object. If you set the checkPolicyFile property of the SoundLoaderContext object to true, Flash Player checks for a cross-domain policy file on the server from which the sound is loaded. If the server has a cross-domain policy file, and the file permits the domain of a SWF file, then the file can stop the loaded sound by using the soundMixer.stopAll() method; otherwise it cannot.
