BBjSysGui::playSoundData

Description

In BBj 22.0 and higher, this method plays the sound encoded in a string of bytes.

Syntax

Return Value Method
void playSoundData(string bytes)
void playSoundData(string bytes, boolean loop)
void playSoundData(string bytes, boolean loop, string mime)

Parameters

Variable Description
url The raw byte data of the audio to play, or "" to stop playing previously specified audio.
loop If this boolean value is true, the audio will play in a loop until stopped.
mime The BUI client requires an audio MIME type, which can usually be determined automatically from the sound data. If it's unable to automatically determine the MIME type (e.g. "audio/wav"), you can explicitly specify it here.

Return Value

None.

Remarks

Each client defines its own set of supported audio formats. Browsers support a broad range of formats, but the Java GUI client is usually limited to AU, AIFF, and WAV.

Mobile browsers only allow sounds to play as a direct result of user action, so this is treated as a no-op in iOS and Android when running in BUI.
