Denoise a Wave for temporal measurements

Usage

clean_wave(
  wave,
  filter = "fir",
  min = NULL,
  max = NULL,
  gate = 0.05,
  oscillo = TRUE
)

Arguments

wave: a Wave object.
filter: Character. Select a bandpass filter. Options are 'fir' (Finite Impulse Response);'bwf' (Butterworth); and 'freq' (Frequency filter).
min: Numeric. The minimum frequency for the bandpass filter.
max: Numeric. The maximum frequency for the bandpass filter.
gate: Numeric (double). The proportion of the maximum amplitude to use as a threshold for the noise gate. The values below this threshold are clipped to zero.
oscillo: Logical. If TRUE (default), a simple oscillogram of the output wave is plotted.

Value

a Wave object

Details

This function was developed as a preprocessing step for temporal measurements only. DO NOT conduct spectral analysis on objects returned by this function.

Examples
