sinetone | R Documentation |
Generate discrete sine tone.
sinetone(freq, rate = 8000, sec = 1, ampl = 64)
freq |
frequency of the tone, specified as a vector of positive numeric
values. The length of |
rate |
sampling frequency, specified as a positive scalar. Default: 8000. |
sec |
length of the generated tone in seconds. Default: 1 |
ampl |
amplitude of the tone, specified as a vector of positive numeric
values. The length of |
Sine tone, returned as a vector of length rate * sec
, or as a
matrix with rate * sec
columns and max(length(freq),
length(ampl))
columns.
