If this were a first order filter you could probably hear the resultant
half dB approx. at 10kHz. I think I may be able to do that.
Do you? I'm amazed.

David.
Probably not with music, but I've just tried it with noise, and it is no
problem at all. Interestingly, I also tried a 17th order Butterworth
filter 3dB down at 20kHz, and although the effect is subtle, I can
reliably identify it.

This, presumably, is an A-B test. If you were presented with just one or the
other without knowing which it was, would you be able to identify it?

David.

That does not mean you can hear the "half dB at 10kHz", since you may well
be hearing the loss of the higher frequencies.

It might be to your dog, listening to sine waves. But 1dB down at 20k
won't make any audible difference to any real world audio signal.

I can hear it, at least certainly used to be able to.

It is certainly wiser to claim you *used* to be able to do something. That
way even if you were put to the test now, and didn't do what was claimed,
your explanation would be to hand. :-)

Just because YOU'RE deaf, don't assume everyone else is.

From what you say, I presume you find it intolerable to listen without
either doing so in an anechoic chamber, or using a clamp to keep your ears
in the same place all the time you listen... or do you only use headphones
because all room acoustics are unacceptable to you? :-)

Slainte,

Jim

WTF no-one chose a sensible sampling frequency and a half sensible bit

20 bit and 60 kHz would have done nicely.

It was designed around the semi-pro video recorders of the day.

However, even your golden ears wouldn't tell the difference between 16 and
20 bit. 14 bit is where most cease to notice any difference.

And what on earth is the point in worrying about frequencies way above the
uppermost harmonics of any musical instrument?

A 1dB change at 20k? I think not.

I certainly don't make extravagant claims from behind my keyboard.

I used to be able to 'hear' - more accurately be aware of - at least 24
kHz.

Designing the CD spec around old deaf ****s was the worst move ever.

You should really do some research on the subject instead of bandying
around figures you obviously don't understand the meaning of in practical
terms.
