Converts a praat_sound object to a data frame with time and amplitude columns. This is useful for plotting and further analysis in R.
Usage
# S3 method for class 'praat_sound'
as.data.frame(x, ...)Value
A data.table (inherits from data.frame) with two columns:
- time
Time in seconds
- amplitude
Amplitude values
Examples
values <- sin(2 * pi * 220 * seq(0, 0.1, length.out = 1000))
snd <- create_sound_from_values(values, sampling_rate = 10000)
df <- as.data.frame(snd)
#> Warning: as.data.frame.praat_sound() is deprecated. Use Sound$as_data_frame() instead.
