Sound
This defines a single sound element that can be used within
the movie. This may be played using a PlaceSound element,
attached to buttons using the ButtonSound element of a
button or accessed using ActionScript if exported as a
symbol. Currently all sounds stored in SWF movies can be
used or any CBR MP3 sound. All sounds must have a sample
rate of 5.5KHz, 11KHz, 22KHz or 44KHz. MP3 sounds sounds are
restricted to 11KHz, 22KHz or 44KHz. If the rendered pitch
and duration of a sound is not as expected then check the
sampling rate of the input sounds.
Attributes
| id | A unique name for the symbol within the movie. | |
| Type | String | |
| format | Optional informational attribute specifying the native format of the sound. Only 'Raw', 'MP3' and 'ADPCM' formats are supported below version 6. | |
| Values | MP3 ADPCM Raw RawPS Nellymoser | |
| Default Value | MP3 | |
| resourceType | The type of file used to store the sound. An SWF file format is an SWF file in which the sound is already pre-processed and stored as SWF. Most commonly, this be be as a result of a previous SWF decompilation. Only MP3 sounds can be read from external file formats. If other sound formats are required to be streamed then they should be either converted to MP3 or imported into a Flash movie using another authoring tool and exported to a .SWF resource file. | |
| Values | External SWF | |
| Default Value | External | |
| resourceLocation | Identifier for this resource within the repository. For the default 'File' repository this indicated the file name within the sounds subdirectory. | |
| Type | String | |
| Default Value | No default | |
| sourceStartTime | Optional attribute specifying the position within the sound at which to start. Position is specified in Milliseconds into the specified sound. | |
| Type | Integer | |
| Default Value | 0 | |
| duration | Optional attribute specifying the duration, in milliseconds, of the sound. | |
| Type | Integer | |
| Default Value | The duration of the timeline or the duration of the sound, whichever is less. | |
| latency | When sounds are converted to MP3 format by Flash, the decoder automatically creates all sounds with a predefined latency, representing the number of sound samples to be skipped. This latency cannot be retrieved by directly inspecting the MP3 produced as it is a property of the built-in transcoder. When the latency is not specified correctly, audible clicks or gaps may be heard when playing the sound. This attribute is not necessary for MP3 sounds created externally and should rarely need to be manually specified by a user. | |
| Type | Integer | |
| Default Value | 0 | |
| sampleCount | When an MP3 sound extracted from an SWF has a defined latency, the number of sound samples present in the sound will differ from those implicitly defined by the MP3 format. When the latency attribute is non-zero, this attribute can be used to specify the actual number of defined samples in the sound. When the sampleCount is not specified correctly, audible clicks or gaps may be heard when playing the sound. This attribute is not necessary for MP3 sounds created externally and should rarely need to be manually specified by a user. | |
| Type | Integer | |
| Default Value | No Default | |
