See the notes in a sonification

Every row of your data becomes a note. notes() shows the result as a tibble: when each note starts (onset, in seconds), how long it lasts, its pitch (as a MIDI number, a note name and a frequency in hertz), how loud it is (velocity, 1 to 127), and the data value it came from. If you mapped time, time_value holds the original time. The row column matches the row number in your original data.

Usage

notes(x)

Arguments

x

A sonification made by sonify_data().

Value

A tibble with one row per note.

Examples

s <- sonify_data(data.frame(x = c(1, 5, 3)), x, instrument = "sine")
