R: Continuous pitch scales

scale_pitch_continuous {playitbyr} R Documentation

Continuous pitch scales

Description

These shortcut functions (with the notation scale_[sound parameter]_[scaling function]) are intended to be added onto a sonify object to specify how [data parameter] from the data (a column of the data) is to be mapped to sonic parameters (here, "pitch", where middle C is represented as 8 and each octave as 1).

Usage

  scale_pitch_continuous(soundlimits, limits = NULL,
    by = NULL, ...)

  scale_pitch_exp(soundlimits, limits = NULL, by = NULL,
    ...)

Arguments

`...`	Other parameters (currently ignored)
`soundlimits`	The limits of the sound parameter.
`limits`	The limits of the data to train, a numeric vector of length 2. All data values outside these limits are returned as `NA`. If `NULL`, the default, the function takes the minimum and maximum of the data
`by`	The unit to round the sound parameter to.

Details

_continuous scales are a linear scaling, whereas _exp is an exponential scale.
