Usage

to_spectrogram_direct(
  sound,
  window_length = 0.005,
  max_frequency = 5000,
  time_step = 0.002,
  frequency_step = 20,
  window_shape = "Gaussian"
)

Arguments

sound

Sound object or external pointer

window_length

Numeric. Window length in seconds (default: 0.005)

max_frequency

Numeric. Maximum frequency in Hz (default: 5000)

time_step

Numeric. Time step in seconds (default: 0.002)

frequency_step

window_shape

Character. Window shape (default: "Gaussian")

Value

External pointer to Spectrogram

Examples

sound <- Sound$create_tone(frequency = 200, duration = 0.5)
spg_ptr <- to_spectrogram_direct(sound, window_length = 0.005)
spg <- Spectrogram(.xptr = spg_ptr)
spg$get_number_of_time_bins()
