## Detailed Description

template<typename FloatType>
class juce::dsp::Bias< FloatType >

Adds a DC offset (voltage bias) to the audio samples.

This is a useful preprocessor for asymmetric waveshaping when a waveshaper is bookended by a bias on input and a DC-offset removing high pass filter on output.

This is an extremely simple bias implementation that simply adds a value to a signal. More complicated bias behaviours exist in real circuits - for your homework ;).
