getSynth: Synthesizer

In benRenard/sequenceR: A Simple Sequencer for Data Sonification

Synthesizer

Description

Creates an additive, Hammond-inspired Synthesizer. Higher harmonics decay faster and have smaller sustain.

Usage

getSynth(
  notes,
  nHarmonics = 5,
  peak = 0.03,
  decay = 0.8,
  duration = 1,
  sustain = 0.25,
  decayPar = 1,
  sustainPar = 4,
  type = "sine"
)

Arguments

notes	Character vector, note names
nHarmonics	Integer >=1, number of harmonics
peak	Numeric, peak time in seconds
decay	Numeric, end-of-decay time in seconds
duration	Numeric, total duration in seconds
sustain	Numeric, sustain volume
decayPar	Numeric, the higher the value the smaller the decay time for higher harmonics
sustainPar	Numeric, the higher the value the smaller the sustain volume for higher harmonics
type	String, oscillator type, one of 'sine', 'saw', 'square' or 'triangle'. If an unknown string is provided, a sine oscillator will be used.

Value

An object of class 'instrument'.

Examples

synth <- getSynth(c('E2','B2','E3','G3','A3'))
w=play.instrument(synth,time=(0:(length(synth)-1))*0.5,fadeout=rep(Inf,length(synth)))
tuneR::plot(w)
## Not run: 
# This line of code is wrapped in \dontrun{} since it relies
# on an external audio player to play the audio sample.
# See ?tuneR::setWavPlayer for setting a default player.
tuneR::play(w)
## End(Not run)
