sweptsine: Generate a sine sweep

In sonicscrewdriver: Bioacoustic Analysis and Publication Tools

Generate a sine sweep

Description

Generates a frequency swept sine wave (either linear or logarithmic) and returns it as a Wave object or vector.

Usage

sweptsine(
  f0 = 100,
  f1 = 2500,
  mode = "linear",
  sweep.time = 1,
  time.unit = "seconds",
  samp.rate = 44100,
  output = "wave",
  ...
)

Arguments

f0	Start frequency
f1	End frequency
mode	One of "linear", "log"
sweep.time	Duration of swept wave
time.unit	One of "seconds", "samples"
samp.rate	Sample rate of swept wave
output	"wave" for a Wave object, or "vector"
...	Additional arguments to pass to data2Wave

Value

A swept wave object of the type specified in output.

Examples

#Generate a swept sine wave between 0Hz and 10kHz.
w <- sweptsine(0, 10e3)

#Generate a swept sine wave between 0Hz and 10kHz and normalise it.
w <- normalise(sweptsine(0, 10e3))

#Generate a stereo swept sine wave between 100Hz and 1KHz.
w <- tuneR::stereo(sweptsine(100, 1e3))

#Generate an exponentially swept sine wave between 100Hz and 1KHz.
w <- sweptsine(100, 1e3, mode="log")
