Apply Hann band-pass filter to spectrum (in-place)

Usage

spectrum_pass_hann_band(spectrum, fmin, fmax, smooth = 100)

Arguments

spectrum: Spectrum object (will be modified)
fmin: Low frequency cutoff (Hz)
fmax: High frequency cutoff (Hz)
smooth: Smoothing bandwidth (Hz)

Value

NULL (modifies spectrum in place)

Examples

sound <- Sound$create_tone(frequency = 150, duration = 0.5)
spectrum <- sound$to_spectrum()
spectrum_pass_hann_band(spectrum, fmin = 300, fmax = 3000, smooth = 100)
# spectrum is now modified
