Linear Phase EQ Orange
Pro Audio Review - PEQ Linear Phase EQ Plug-ins
Algorithmix linear phase PEQs come in two flavors – Orange and Red. Linear phase EQ is a digital filtering process. There is phase shift, or rather latency, but it is the same for all frequencies so waveforms remain intact. The company has built upon standard digital theory with proprietary algorithms that result in absolutely pristine and transparent sound. Internal calculations are done in 64-bit double-floating point with an 80-bit accumulator to prevent overflow. Both EQs will operate at sample rates up to 384 kHz and as such can be used on DXD (352.4 kHz/32-bit) audio. Orange has a remarkable THD+N spec of –140 dB for virtually full 24-bit transparency.
The Orange plug-in excels in purity and absolute transparency. So much so that, for a last minute tweak, I have been able to apply it to already mastered material, even material that has been compressed and peak-limited. It has worked wonders in providing a finishing touch to a master that is almost perfect. I know of no other EQ that allows this without an audible increase in distortion and a loss of clarity.
