Effects.PlaybackRateRatioGet method

Previous pageReturn to chapter overviewNext page



Obtains the current ratio for playback rate of the given player.


When playback is performed at normal speed, its ratio is 1.0; after changing the playback speed through the Effects.PlaybackTempoSet or Effects.PlaybackRateSet methods, the playback speed is altered and this method allows to know which is the updated rate ratio. For example, if the playback rate should be incremented by 20%, the reported playback rate ratio would be 1.2 while, if the playback rate should be reduced by 30%, the reported playback rate ratio would be 0.7.
