soundgen (version 2.1.0)

splitContour: 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

deprecated

jumpThres

deprecated

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.

Details

Splits a smooth contour into several segments. A new segments is started if the time step between two anchors is smaller than discontThres.

Examples

# NOT RUN {
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),
  value = c(360, 316, 345, 550, 610, 590)))
soundgen:::splitContour(data.frame(time = c(0, .4, .45, .6, .8, 1),
  value = c(360, 316, 345, 550, 610, 590)),
  discontThres = .1)
soundgen:::splitContour(data.frame(time = c(0, 1),
  value = c(360, 590)))
