sweptsine: 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",
  ...
)

Value

A swept wave object of the type specified in output.

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"

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")
