void measureMultiplexedChannelDynamics ( const sample *  startSample, const sample *  stopSample, const unsigned char  stride, sample &  min, sample &  max  )

inline

Measures dynamics from samples for a single channel in a multiplexed stream.

Parameters

startSample	Pointer to the first sample the measurement starts from
stopSample	Pointer to the last sample where the measurement stops
stride	Step size in samples
min	Discovered minima value; the passed value is not reset
max	Discovered maxima value; the passed value is not reset
