Creates a time-frequency heatmap visualization of a Spectrogram.

Usage

# S3 method for class 'Spectrogram'
plot(
  x,
  from_time = NULL,
  to_time = NULL,
  from_freq = NULL,
  to_freq = NULL,
  garnish = TRUE,
  title = "Spectrogram",
  dynamic_range = 70,
  ...
)

Arguments

x: Spectrogram object
from_time: Start time in seconds (NULL = from beginning)
to_time: End time in seconds (NULL = to end)
from_freq: Start frequency in Hz (NULL = from 0)
to_freq: End frequency in Hz (NULL = to Nyquist)
garnish: Logical. Add axis labels and title (default: TRUE)
title: Character. Plot title (default: "Spectrogram")
dynamic_range: Numeric. Dynamic range in dB (default: 70)
...: Additional arguments passed to the underlying function or ignored.

Value

A ggplot2 object

Examples

sound <- Sound$create_tone(frequency = 220, duration = 0.5)
spectrogram <- sound$to_spectrogram()

# Basic plot
plot(spectrogram)


# Focus on speech range
plot(spectrogram, to_freq = 5000)
