Detailed Description

The purpose of this class is to deal with timing based on the sample rate and do the proper conversions.

◆ getNextBarSampleCount()

TSamples pongasoft::VST::SampleRateBasedClock::getNextBarSampleCount ( TSamples  iCurrentSampleCount,
double  iTempo,
int32  iTimeSigNumerator = 4,
int32  iTimeSigDenominator = 4 
) const

Given the current sample count (which can be extracted from ProcessData::processContext->projectTimeSamples) returns the number of samples for the next bar boundary.

Example: with a tempo of 120 (4/4), and a sample rate of 48000, each bar is 96000 samples. 

getNextBarSampleCount(52123, 120) == 96000; // 1 bar
getNextBarSampleCount(600000, 120) == 672000; // 7 bars
getNextBarSampleCount(672000, 120) == 672000; // 7 bars
getNextBarSampleCount(672001, 120) == 768000; // 8 bars
