Inheritance diagram for yase::Wavetable: Collaboration diagram for yase::Wavetable:A wavetable oscillator.
The path argument to the constructor should point to a .wav file that has 64 sections of 1024 samples. Each section should be one cycle of the oscillator. You can use the morph input (in [0,1]) to choose the wave to play. The oscillator will interpolate between waves. For example, inputing w=0.1482 result in the following linear combination of waves floor(64*w) = 9 and ceiling(64*w) = 10:
(1-64*w) * 9 + 64*w*10
Example wavetables of the correct format can be found in the wavetables directory.
| [in] | morph | A value in the interval [0,1] |
| [in] | amplitude | |

This method should be overridden by derived classes. It will be called repeatedly by a synthesizer at a frequency determined by SAMPLE_RATE.
Reimplemented from yase::Oscillator.
