public class FSSoundStreamBlock
FSSoundStreamBlock contains the sound data being streamed to the Flash Player.
Streaming sounds are played in tight synchronisation with one FSSoundStreamBlock object defining the sound for each frame displayed in a movie.
Attributes | |
---|---|
type | Identifies the data structure when it is encoded. Read-only. |
soundData | The encoded sound data for a single frame in a movie. The format for the sound is defined by an FSSoundStreamHead object. Sounds may be encoded using the uncompressed PCM (big or little endian byte order), compressed ADPCM, compressed MP3 or NELLYMOSER formats. |
When a streaming sound is played if the Flash Player cannot render the frames fast enough to maintain synchronisation with the sound being played then frames will be skipped. Normally the player will reduce the frame rate so every frame of a movie is played.
The FSSoundStreamBlock class represents the SoundStreamBlock tag from the Macromedia Flash (SWF) File Format Specification. It was introduced in Flash 1 with support for Uncompressed PCM encoded sounds (both Little-Endian and Big-Endian formats) and the compressed ADPCM format. Support for MP3 was added in Flash 3. The Nellymoser Asao format was added in Flash 6.
Field Summary |

FSSoundStreamBlock(byte[] bytes)
Constructs an FSSoundStreamBlock specifying the sound data in the format defined by a preceding FSSoundStreamHead or FSSoundStreamHead2 object. |
|
FSSoundStreamBlock(FSCoder coder)
Construct an FSSoundStreamBlock object, initialising it with values decoded from an encoded object. |
|
FSSoundStreamBlock(FSSoundStreamBlock obj)
Constructs an FSSoundStreamBlock object by copying values from an existing object. |
