getSynth: 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"
)

Value

An object of class 'instrument'.

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.

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)
if (FALSE) {
# 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)}
