Class Method Summary

• .saw_wave(sins : Int, lfo_hertz : Float64 = 0.0, lfo_amp : Float64 = 0.0) : Wave

  Calculate a sawtooth wave by addition of sine waves the more sins specified, the closer the waveform will match a straight sawtooth wave /|/|/|/|

• .saw_wave(lfo_hertz : Float64 = 0.0, lfo_amp : Float64 = 0.0) : Wave

  Calculate a sawtooth wave /|/|/|/|
