What's this new obsession that some folks have with content below 35Hz? Is it only in EDM? Because, frankly, I don't miss it in my music.
(This is not aimed at the OP, I'm just asking.)
Hi Gordon, yeah, I don't listen to much below 35hz either.
From what little EDM I have heard, my guess is that below 35hz is more about feel, bodily vibration, than auditory.
Or maybe better said, integrating body vibration with auditory vibration.
Almost ridiculously, I've been a phase=o=holic lately.
My interest in removing a HP filter is not about extending LF, but about optimal phase alignment for highest possible sound quality.
Here's a post from a guy that makes alot of sense to me, and matches what many others are starting to say about linear phase.http://www.diyaudio.com/forums/multi-way/283068-mini-synergy-horn-experiment-25.html#post4554771
I had been trying to flatten phase all the way down to lowest freq, but it wasn't sounding right, so now I'm trying to match magnitude and phase rolloff.
So, this HP filter question is really just about trying to follow the recommendation in the link regarding system highpass phase.
A HP filter in play makes doing it a bit trickier...
I wholeheartedly agree with linear phase improving transients, increasing vocal clarity, and giving bass impact.
The transient improvement is a little difficult to judge sometimes, as I've found I can be fooled by small amounts of HF/VHF change.
Bass can be tough too, with reflections and all.....
But vocal clarity never seems to lie...my trusted test is how well backing vocals come through.
Hey, if we ever get speakers that go to zero hz, then maybe flat linear phase to zero, with no system highpass.....
..... will fully integrate being bodily rocked and audibly rolled
