Thanks @OMas
Feel free to post a bit about what exactly itโs doing and how it would benefit someone on their mixes. I barely understand it myself if Iโm being totally honest.
Hey Holster,
No worries, and thanks for being honest! So, maybe Iโll start with linear phase (LP) versus minimum phase (MP)โฆAll real world electrical equalizers, both passive and active, can be mathematically considered โminimum phase.โ They exhibit the frequencyโdependent gain we use EQs for, plus they also shift phase depending on frequency as well. This combination is what we think of when we hear traditional EQs, even if weโre not aware of the temporal phase component.
Linear phase EQs do not exist in the real world, being a mathematical construct best realized in the digital domain. Unlike MP EQs, LP EQs exhibit constant phase shift at all frequencies. That is functionally equivalent to a simple delay. Another way to think of LP EQs is that they are โpureโ equalization, with only frequencyโdependent gain. Because they lack frequencyโdependent phase shift, they sound different from MP EQs.
We manufacture two LP EQs, thEQred and thEQorange, as well as two MP EQ products. thEQred is a frequency domain LP EQ. It uses FFTs or Fast Fourier Transforms to represent frequency and to process the user requested gain versus frequency. Our thEQorange uses time to process the user requested gain versus frequency. Unlike any other LP EQs on the market, ours are purposeโbuilt for a particular range of use cases. Also, ours are zero compromise in their implementation.
With one exception, all digital LP EQs are of the frequency variety. thEQred is also built that way but uses very high internal (64 & 80 bit) precision and heroic SRC (Sample Rate Conversion) when operating at baseband sample rates (44.1 and 48k) to achieve very low, industryโleading noise and distortion. Compare its sound to what else is out there and youโll hear the difference.
thEQorange is a very rare beast. It is a forwardโbackward LP EQ. This approach first passes incoming samples all the way through the EQ processing, then reverses the data stream and runs it backwards through the EQ processing. The result of those two steps and then compared and the result is passed to the output. This elaborate forwardโbackward process cancels processing artifacts. thEQorange also uses very high internal (64 & 80 bit) precision and advanced SRC for super low distortion and noise.
thEQred was designed to be the ideal LP EQ for โbeautyโ applications; whenever you want to make audio โbetter.โ On the other hand, thEQorange was designed for remedial or repair situations, where there is midband and/or low frequency congestion, bloat or tubbiness that needs help.
Hope all that makes sense. Whatโs on sale this month is thEQlp, an annual subscription for both of our LP EQs together as a bundle. Youโll find it on both LP EQ product pages via the Purchase Now button.

As to how either would benefit someone on their mixes, all I can say is; Do they sound better than what youโre using or just different? The answer to that is heavily dependent on your room, your โearsโ or hearing, and your equipment. Unlike our MP EQs, the two LP EQ products are designed primarily for mastering, where every tiny contribution to quality is taken into consideration

Thanks for the breakdown! I really just need to spend some focused time on both types to really hear the differences in how they behave. 
One mentionโฆfor those of you new to small business accounting, subscriptions to software, industry magazines, and professional societies like the AES are all deductible as a business expense.
