notes {voice}

Assign notes to frequencies

Description

Returns a vector of notes for equal-tempered scale, A4 = 440 Hz.

Usage

notes(x, method = "spn", moving.average = FALSE, k = 11)

Arguments

x

Numeric vector of frequencies in Hz.

method

Method of specifying musical pitch. (Default: spn, i.e., Scientific Pitch Notation).

moving.average

Logical. Must apply moving average? (Default: FALSE).

k

Integer width of the rolling window used if moving.average is TRUE. (Default: 11).

Details

The symbol '#' is being used to represent a sharp note, the higher in pitch by one semitone on Scientific Pitch Notation (SPN).

Value

A vector containing the notes for equal-tempered scale, A4 = 440 Hz. When ‘method = ’spn'‘ the vector is of class ’ordered factor'. When ‘method = ’octave'‘ the vector is of class ’factor'. When ‘method = ’midi'‘ the vector is of class ’integer'.
