Constructor Detail
A new instance of Oscillator. The controllable wave parameters are frequency, amplitude, phase offset, and DC offset. The current phase angle is initialized to the given phase offset.
@param [Hash] args Hashed arguments. Required key is :sample_rate. Optional keys are :wave_type, :frequency, :amplitude, :phase_offset, and :dc_offset. See ARG_SPECS for more details.
Instance Method Detail
Set the frequency (also updates the rate at which phase angle increments).
Set the phase angle offset. Update the current phase angle according to the difference between the current phase offset and the new phase offset.
