Plot Pitch and Intensity Together

Creates a dual-axis visualization showing pitch and intensity contours together. This replicates Praat's Pitch_Intensity_draw() function.

Usage

plot_pitch_intensity(
  pitch,
  intensity,
  from_time = NULL,
  to_time = NULL,
  pitch_color = "darkgreen",
  intensity_color = "darkorange",
  title = "Pitch and Intensity",
  ...
)

Arguments

pitch

Pitch object

intensity

Intensity object

from_time

Start time in seconds (NULL = from beginning)

to_time

End time in seconds (NULL = to end)

pitch_color

Character. Pitch line color (default: "darkgreen")

intensity_color

Character. Intensity line color (default: "darkorange")

title

Character. Plot title (default: "Pitch and Intensity")

...

Additional arguments passed to the underlying function or ignored.

Value

A ggplot object with dual y-axes

Examples

sound <- Sound$create_tone(frequency = 220, duration = 1.0)
pitch <- sound$to_pitch()
intensity <- sound$to_intensity()

# Combined plot
plot_pitch_intensity(pitch, intensity)

# Time range
plot_pitch_intensity(pitch, intensity,
                    from_time = 0.2, to_time = 0.8)
