Single-zero preemphasis filter.
1 2 | preemphasis (input, cutoff = 50, fs = 22050, verify = FALSE,
coeff = 0)
|
input |
Either a numeric vector representing a sequence of samples taken from a sound wave or a sound object created with the loadsound() or makesound() functions. |
cutoff |
The spectral slope is increased by 6 dB. per octave above this frequency. |
fs |
The sampling frequency of the sound. If a 'sound' object is passed, this does not need to be specified. |
verify |
If TRUE, before and after spectra are plotted to allow the user to visually verify the process. |
coeff |
Optionally, the single coefficient used by the filter may be specified. |
The modified sound is returned. If a 'sound' object another 'sound' object is returned.
