Detailed Description

template<typename T = float>
class audio_tools::Filter< T >

Abstract filter interface definition. Subclasses implement process() to transform audio samples one at a time. Use reset() to clear internal state (e.g. delay lines) without changing the filter coefficients.

process()

template<typename T = float>

virtual T process ( T in )

pure virtual

Processes the input value and returns the filtered output value.

reset()

template<typename T = float>

virtual void reset ( )

inlinevirtual

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