...requencies result in longer waves. But that?s not all: as frequencies increase, it appears that wavelengths increase to infinite length, then get shorter again as the wave reverses, then it gets longer and flips again. Here?s a small file that demonstrates the bad sawtooth waves: library(tuneR) sample_rate <- 12000 reverse <- FALSE mycolors=c("red","orange","yellow","green","cyan","blue","violet","magenta") plot(sawtooth(110,duration=round(sample_rate/100),samp.rate=sample_rate,xunit="samples")@left,type=&...

Ccing the maintainer if the tuneR package. Looks to me like sawtooth (and square) don't behave as expected when using xunit="samples". Workaround is to use xunit="time" instead: sawtooth(110,duration=1/100,samp.rate=sample_rate,xunit="time") I looked at the code but found it to be opaque. -- Sent from my phone.
