Create Common Window Function XPtr

Convenience function to create pre-defined window functions as compiled XPtrs. Requires the RcppXPtrUtils package.

Usage

create_window_xptr(
  type = c("hamming", "hanning", "gaussian", "triangular", "blackman", "rectangular"),
  sigma = 0.25
)

Arguments

type

Character, one of "hamming", "hanning", "gaussian", "triangular", "blackman", "rectangular"

sigma

Numeric, standard deviation for Gaussian window (default 0.25)

Value

External pointer to compiled window function

Examples

# \donttest{
# Compiling a C++ window function takes a few seconds
if (requireNamespace("RcppXPtrUtils", quietly = TRUE)) {
  hamming <- create_window_xptr("hamming")

sound <- Sound$create_tone(frequency = 220, duration = 0.3, sampling_rate =
 16000)
  windowed <- apply_window_xptr(sound, hamming)
}
# }
