This bit delves into the use of linear phase EQ to address phase rotation issues caused by equalizers. By employing a linear phase setting, you can maintain phase integrity, avoiding interference and ensuring the phase stays at 0°, as demonstrated with the free Burum EQ analyzer.
While linear phase filters are beneficial for preserving phase relationships, they can introduce pre-ringing distortion, which affects transients. However, this distortion is minimal, making the advantages of linear phase EQ outweigh its drawbacks.
The bit also highlights the challenges of parallel processing, where phase interference can occur if phase rotation is introduced. By using linear phase EQ in parallel setups, you can prevent destructive phase interference and maintain the integrity of your mix.
