Processes the input value and returns the filtered output value.

Implements Filter< T >.

reset()

virtual void reset ( )

Clears the internal state (delay lines) without changing the coefficients. Call after reconfiguring filter parameters via begin() to avoid transients from stale state.

Reimplemented in FIR< T >, IIR< T >, BiQuadDF1< T >, BiQuadDF2< T >, BiQuadDF2< float >, SOSFilter< T, N >, and FilterChain< T, N >.
