question: protected long unScaleTime ( int reqSampleRate , long timelineTimeInSamples ) { if ( reqSampleRate == sampleRate ) return ( timelineTimeInSamples ) ; return ( Math . round ( ( double ) ( sampleRate ) * ( double ) ( timelineTimeInSamples ) / ( reqSampleRate ) ) ) ; }
target:  Unscales a discrete time from the timeline's sample rate.
