Peter,

The overlap is 800-2500/3000 Hz range, right were most crossover are located.

Ear dominance: both ears are not equal in hearing ability, and both pathways don't interpret the sounds, one side pathway is dominant!

Reflections: don't forget the complex reflections in the local level ....the pinna (ear lobe) upper chest, and head transfer functions. Everyone's pinna is unique and therefore the hearing. Ears like reflections, even order harmonics help too! People get disoriented in anechoic chambers because the lack of reflection limits localization and orientation.

Background noise ..... no matter how low the noise level is in the body has internal noise. The heavy beating of the heart one become alerted to "only" in frightening situations .... but is present all the time.... but our brain ignores it.

Mani:
devil is in the details. First partly psychological since one will never critically listen to the radio. Radio is also playing at a lower level. Less details, less for the ears to be alerted to. Also radio is mono, so no stereo localization.

Oh forgot: almost all songs played on radio are tweaked for such a system  Wink "radio edit". No need to elaborate  Happy

Edit: Re- reflections
Human ears are reliant on reflections for a lot of things, behind in the subconscious mind, the brain has already oriented "one" to the dimensions of the room. When one speaks, or some noise, the sound is spread all around, and reflections are recorded and analyzed for location and orientation. Mind you this takes an instant. After than the brain is "constantly" checking for this .... so reflections are in fact "not" distortions as commonly conceived but crucial part of the human psychoacoustics ....  so when a noise arrives it will be checked for its position, and if it does not contain some of the parameters of the listening/event space, the first part of authentication fails. Beaming speakers will fail, and fail miserably because the listening space is infinitely small and any head movement caused the sound stage to shatter. On the other hand too wide a dispersion, as my prior Omni, will cause loss of detail. Also Omnis can't handle transients.
Dynamically Controlled reflection are the next frontier in HiFi  Cool

Part 2:

Ok one more thing to clear

The human ear will use different parameters to diffentiate different frequencies

Group delay for higher frequencies (most important)
Phase delays for lower frequencies

Hearing has evolved over millions of years, and perfected. Hearing is not by first reflection "only", but a combination of the first and associated reflections ... just the process of evolution.


All require lengthy explanations for the general public, but Peter knows  thankyou

Part 1


Also a few more things to consider: (finally some time to think and write)

Can you hear the person next to you at 85-90 dB in a normal conversation when the music is playing? Does this or your regular volume seem louder than it is?

The reason is there is a possibility higher order harmonics have made their way into the system, even thought it might be negligible or non detectable, but those are the ones responsible for the hearing cues.  And exibit as above.
Also these are also responsible for limiting the sound field.

Of course it could be nothing or a more complicated process which includes this, or an entirely unrelated reason.

Best,
VJ

Hi Peter,

Look into purist stereo recordings.

It may help reassess.

Peter,

I'll pass ....







Just kidding!!

Ramesh,

Congrats!!

Welcome to the Orelo MK-II club. Happy

Looking forward to your updates.

No cables necessary!! Wink

Ramesh : I'll be not surprised if the 4C is similar!! cr*ppy interiors ... lol

Looking forward to your visit.

Jud: AR continues its usual troubled existence. Aah the red ... perfectly meets 4C Happy

Guys,

That's incredible memory!!  How many years has it been?! .... Wow!!!

I watched that movie too, quite disappointed by it!!

I looked into the WRX myself, it's a great car. Tweakers paradise, especially in CA with its thriving underground racing scene and third party modifiers.... still on the radar, decided can't give it that much attention right now!

The AR-4c, looks like a muscle car in some angles, and not on some. By numbers alone it's not impressive, but surprises you by its performance again. I would call this smart engineering, and not just brutal force as most American muscle cars.

Cheers,
VJ

P.s. Peter: The sign announces  love this   Being played here

Hey Mani,

Thanks !!

I agree with your assessment, but man it's my first Italian, and a refreshing experience to drive a driver dedicated car! Every time you get into it, it makes you feel special Wink

Also in a city where supercars are as common as superstars, this stands it's ground!

I'll be tracking it soon, no garage queen here :D

Cheers,
VJ

I had ticks with 1.03 on W8.

I changed the USB port (3.0 to 2.0) and the USB/FIFO errors stopped.
I suspect powers supply issues.

Short Clarixia on the PC side.
