Split contour
Description
Internal soundgen function
Usage
splitContour(anchors, discontThres = 0.05, jumpThres = 0.01)
Arguments
anchors |
a dataframe with two columns: time and value (time on any scale) |
discontThres |
if two anchors are closer in time than
|
jumpThres |
if anchors are closer than |
Details
Splits a smooth contour into several segments. A new segments is started if the time step between two anchors is smaller than discontThres.
Value
Returns a dataframe containing the index of anchor rows for start and end of each segment and whether we want a transition or a jump between segments.
Examples
soundgen:::splitContour(data.frame(time = c(0, 370, 650, 655, 1050, 1400),
value = c(360, 316, 345, 550, 610, 590)))
soundgen:::splitContour(data.frame(time = c(0, .2, .205, .8, .81, 1),
value = c(360, 316, 345, 550, 610, 590)))
soundgen:::splitContour(data.frame(time = c(0, .4, .45, .6, .8, 1),
