| noisew {seewave} | R Documentation |
This function generates noise.
noisew(f, d, type="unif", listen = FALSE, output = "matrix")
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 |
output |
character string, the class of the object to return, either
|
Uniform noise is generated using runif and gaussian noise is based on rnorm
A new wave is returned. The class of the returned object is set with the argument output.
