  Excuse me... could you make some pedagogy please ?
How do you see the distortion in the spectral decay ?

 
You look at the curve at 0 ms, where it says -35 dB, suss out how much the curve differs from a flat line and that's your distortion in what is potentially the most important facet of sound quality, the frequency response.

And what do you think of my last CIEM (be indulgent please... it is a in-ear thing) and it's me

Not sure. Try changing periods to ms for an easier time.

When we are at the impressionable age of 16 we walk into our friends den to see the Father listening to a bit of Classical on a giant system. What is this? This is an audiophile on a journey.


Wow we can't afford a rig like that he must know what he is doing.


Ya, the Son says. It re-creates the sound of live music. Oh he thinks he is listening to live music?


40 years later we ourselves sit and listen to the same type of rig, maybe digital. Nothing has ever changed, Hi-FI is Hi-Fi and it never really sounded like live music. We knew that at 16, but still chose to chase the illusion.

Another 40 years from now someone will wonder if Hi-FI is treble-centric.

 
True...
 
 
...but that illusion works better than this illusion:
 

 
...or this one...
 

 
 
 
 
 
...or these ones...

Ok, now try align the signal in the graph so that the decay starts just past 0 ms, and so the graph in total extends to about 4 ms.

Hum, hum

( i forgot the measurement system delay)

Now all that's left is to reduce the time axis to 0-4 ms.

It's not bad. You can use EQ to force the response flat at the microphone and see what happens to the decay.

The final illusion is when your conducting the stereo in real-time. The musicians now change pace and volume to your every hand movement.

Sorry, i always need truer lies to keep the illusion alive... it's so... human.

Thanks

 
Here you can see a 50Hz sine wave... 20ms

 
Could you place this sine wave on the CSD please ?

On which axis will you place it ?

^Not sure why you'd do that. Here's what I'd like you to do.
 

 
Faster decay as you approach a flatter response at a given point with digital filtering.
 
Another way to use digital filters to improve sound quality - for those who don't believe in it - is this.
 

 
Unfiltered left, filtered right. Though to be fair, this doesn't work with all types of ringing and can be sensitive to positioning.

Ok, i was thinking that you expected a faster decay in the lows...

 
I can't use equalizers or digitial filters with my test rig... but i always focus my passive filters equalizations on the most sensitive part of the spectrum.
2ms spikes after 10K are not in my critical zone (125 et 8 000 Hz), and the 3K spike is REAG compensation.
 
And i'm agree that spikes in that zone can be atrocious, yes, yes and yes !

The final illusion is what the sound engineer do on the mastering process !

That looks like my bedsheet in the morning.
