Same here. My hearing falls off at 16K Hz and all filters and upsampling sound the same to me.

 

and some told you that reconstruction filters relate to higher frequencies only, right ?

Expectation bias that is !

haha

Accept for the unavoidable fact that the room plays a huge role in the sound. 

Agree and how the whole recording studio is setup. Both the listening room and the recording room do affect the final sound. one can't get away from it.

Hi Jud,

 

Breaking out in cold sweat might be more related to being inside an fMRI machine than perceiving the effects of ultrasonic frequencies. Just guessing ;)

 

 

 

🙂 No fMRI in these particular studies.

I definitely prefer linear phase, too. I wonder if some people are more sensitive to phase issues?

 

It may have quite a bit to do with speakers and room.  With speakers like mine, set up to be linear phase, non-linear-phase filters obscure the imaging and soundstaging qualities owners seek.

 

On the other hand, if you have room configuration causing a frequency-dependent timing problem and you can't easily change the room, then a non-linear-phase filter can be your friend.

 

And of course there are many other uses for such filters.

Another sentence that isn't going to turn out well.

 

Hopefully no one takes it too personally and doesn't mind some curmudgeonly (provocative?) input :)

Interesting.  I strongly prefer minimum-phase (even with single-drivers (headphones) that would be analogous to your phase-coherent speakers), exactly for the reasons you state for linear phase- soundstaging, but also tone.

Actually, I was expecting there to be a difference but I could not point it out in blind testing.  Maybe, it I had used a leaky filter the result would be different?

How can something too subtle to be consciously noticed have an emotional effect?  There is academic research showing emotional effects up to and including breaking out in a cold sweat from subconscious stimuli.

 

I'd have to be convinced it wasn't a placebo effect.

Not always. Depends.

I assume Miska (1) doesn't have superhuman hearing, and (2) might do a reasonable job at being able to discern differences in HQPlayer filters.  (Either assumption could be wrong of course, the second more likely.)

 

If true, this might mean different emotional reactions to music played through filters in which the untrained cannot consciously discern differences.

 

 

What's rarely mentioned is what I consider the main thing happening - the circuitry doing the filtering is altering the pattern of electrical behaviour that the sensitive analogue areas are reacting to, as an interference artifact - and the subjective SQ alters.

 

This was so obvious on an ambitious rig I listened to - changing the filters changed the nature of the SQ degradation - the only setting that 'worked' was bypassing that filtering circuitry, altogether 🙂,

Bedroom studios, but rarely if never in purpose made sound studios. For one thing there's often more than one set of ears, and even then, if only the producer or mixer, headphones have a different sound than speakers in the 'booth.' Musicians recording do wear headphones, often because they are playing in different rooms, or one at a time.
