#include <oscillator.hh>
Inheritance diagram for yase::Oscillator: Collaboration diagram for yase::Oscillator:An abstract base class from which oscillators like Sine, Saw, and Triangle are derived.
This module provides methods and I/O that most oscillators need. It also updates a basic phasor in the protected variable phase which can be used by derived classes to build more complex signal outputs. For a simple example see include/square.hh and include/square.hh which define a raw square wave oscillator.
| [input] | frequency The frequency of the phasor |
| [input] | amplitude The amplitude of the oscillator (derived classes should scale their outputs by inputs[amplitude], it is not done automatically) |
| [input] | modulation A modulation input that modules that rate of the phasor |
| [input] | tuning This input has units in Cents. It tunes the input frequency of the oscillator. |
| [input] | harmonic The harmonic of the oscillator. The actual frequency will be frequency * 2^harmonic |
| [output] | signal The output of the oscillator |

This method should be overridden by derived classes. It will usually be called once, after all modules and connections objects have been added to a synthesizer, but before the synthesizer starts running.
Implements yase::Module.

This method should be overridden by derived classes. It will be called repeatedly by a synthesizer at a frequency determined by SAMPLE_RATE.
Implements yase::Module.
Reimplemented in yase::AdditiveSaw, yase::AdditiveSquare, yase::AdditiveTriangle, yase::Clock, yase::Jenny, yase::Noise, yase::OscGroup, yase::Saw, yase::Sine, yase::Square, yase::Triangle, and yase::Wavetable.
