PartitionGranularity

is an option for audio analysis functions that specifies the partitioning of the audio.

Details

PartitionGranularity can specify the length of partitions and how much they overlap, as well as a smoothing window applied to partition samples.

Typical settings include:
dur partitions of length dur seconds and automatic overlap

{dur,offset} uses the specified offset

{dur,offset,wfun} applies wfun to each partition
Specifications for dur and offset can be scalars, time quantities or "Samples" quantities.
Offset specification can also be Scaled[s], which is equivalent to s×dur.
The smoothing window wfun can be specified using a window function, such as HannWindow, that will be sampled between and or a list of the same length as dur.

Control the partitioning parameters in AudioLocalMeasurements:

Top

	dur	partitions of length dur seconds and automatic overlap
	{dur,offset}	uses the specified offset
	{dur,offset,wfun}	applies wfun to each partition
