Allpassphase

To repair excessive phase smear, use a (an inverse allpass) or simply minimize the number of cascaded allpass stages.

Because all-pass filters can manipulate time delay across frequencies without dropping volume, they are incredibly versatile tools across multiple industries. 1. Phase Equalization (Delay Correction) allpassphase

Mathematically, a first-order all-pass filter is defined by the transfer function: To repair excessive phase smear, use a (an
