tone: Produce a synthesized sound

In shill1729/synthesizer: Synthesize sounds, melodies, chords, and stochastic compositions

Description

Wrapper to seewave::synth() function to produce a pure sine-wave tone. Additional parameters available for different wave forms, soon to be implemented.

Usage

tone(midi, rhythm, harmonics = 1, n = 4, bpm = 120, sampleRate = 48000)

Arguments

midi	the midi note number for the tone to produce
rhythm	the duration of the note in fractions of a measure
harmonics	the amplitude of the harmonics
n	number of beats in a measure
bpm	the beats per minute
sampleRate	the sample rate of the device typically windows is 48000 and mac osX is 44100

Details

The rhythms are converted to seconds via the number of beats per measure and bpm. Midi notes in 0-127 are converted to frequencies in Hertz. The harmonics may either be a vector with leading component unity followed by amplitudes in the interval (0,1) or simply the number one.

Value

numeric vector
