The EBU (European Broadcasting Union) have defined 0dBFS digital to
mean
+18dBu analogue after conversion.


Interesting.
Can you let me have a reference to the technical paper for that.
Cheers,


EBU R68-2000. I'm emailing you a copy directly.

Received, thanks.

With 0dBFS as =18dBU, that would mean OVU (+4dBU) would be -14dBFS. Most
people I know line-up their Pro Tools rigs for -18dBFS for 0VU hence
OdBFS is going to be +22dBU.
Isn't it a lovely world!

Standard are great, that's why we have so many of them!

Decibels, to me, seem to be overused, particularly with digital audio. And
particularly because silence is negative infinity decibels, which isn't a
lot of good if you're writing a computer program that can only cope with
real numbers. What's wrong with plain old 0% to 100%?!
(Rhetorical question, don't feel obliged to answer...)

Are you trying to put us out of a job?

Not much danger of that, if he's such a bad programmer! :-)

BTW, what's wrong with 0-100% is that our hearing is logarithmic, so
deciBels give a much better idea of how things sound. A 10dB increase
in SPL sounds twice as loud, but takes ten times the power.
