fft_spectro
Description
Calculates low frequency power spectrogram of vocalic interval of speech signal. Following method of Tilsen & Johnson (2008)
Usage
fft_spectro(x, f_out = 80, window_size = 256, padding = 2048, plot = TRUE)
Arguments
x |
a 'tuneR' "Wave" object or the path to a .wav file. |
f_out |
the sample frequency for the output |
window_size |
number of samples to calculate each spectrum over |
padding |
length to zero pad signal to. If signal is longer than padding, this will be increased. |
plot |
if true a spectrogram will be plotted |
Value
Returns a tibble with frequency (Hz), time (s) and power
