SoundComposer.ItemSoundFileDurationGet method |
|
Remarks
Obtains the current effective duration of the sound file item by keeping count of eventual duration changes subsequent to the usage of the SoundComposer.ItemSoundFileLoadRangeSet or SoundComposer.ItemSoundFileDurationStretch methods.
The returned value doesn't keep count of eventual loops requested through the SoundComposer.ItemSoundFileLoopSet method: when more than one loop is applied you may obtain the effective duration by multiplying the value returned by this method with the current number of loops returned by a call to the SoundComposer.ItemSoundFileLoopGet method.
For further details about sound composing see the the SoundComposer object and the How to compose a sound tutorial.
