praatScriptCentreOfGravity.Rd
This function generates a Praat script fragment which can be passed as the praat.script parameter of processWithPraat, in order to extract one or more spectral centre of gravity (CoG) measurements.
praatScriptCentreOfGravity(powers = c(2), spectrum.fast = TRUE)
A vector of numbers specifying which powers to query for to extract, e.g. c(1.0,2.0).
Whether to use the 'fast' option when creating the spectrum object to query .
if (FALSE) {
## Perform a search
results <- getMatches(labbcat.url, list(segment="I"))
## Get centres of gravity for all matches
cog <- processWithPraat(
labbcat.url,
results$MatchId, results$Target.segment.start, results$Target.segment.end,
praatScriptCentreOfGravity(powers=c(1.0,2.0)))
