noise {seewave} | R Documentation |
This function generates noise.
noise(f, d, type="unif", listen = FALSE, Sample = FALSE)
f |
sampling frequency of the signal to be generated (in Hz) |
d |
duration of the signal to be generated. |
type |
a character string to specify the type of noise, either "unif" or "gaussian". |
listen |
if TRUE the new sound is played back. |
Sample |
if TRUE and plot is FALSE
returns an object of class Sample |
.
Uniform noise is generated using runif
and gaussian noise is based on rnorm
If plot
is FALSE
, a new wave is returned as a one-column matrix
or as a Sample
object if Sample
is TRUE
.
