Re: broadcast sound quality

[Michael Drainer]

What exactly do you mean by maximum defination? Anytime you are dealing
with the sattelite/broadcast world, it is critical that you keep your output
peak levels below 0 dBm or -20 dBFS. If you are running much hotter, you
WILL get calls from those who receive the downlink. If you are looking to
maximize the percieved "Loudness" of the program material, you can compress
the snot out of the signal then boost the gain but depending on the program
material, you will be doing more harm than good.

"Broadcast" sound quality... Yeeeechhh!!! Heh heh... :-)


Only really great sounding broadcasts I've ever heard were classical
stations. Sometimes they use considerably less limiting & compression, or
just less signal processing all the way around.


Seriously though, the reason to operate at an "optimum" level, i.e. highest
level where no clipping occurs, would be to have good signal level to
customers on the receiving end and the lowest possible noise floor.
Otherwise, a compromise involving lower level settings could offer more head
room. It's a trade off. For broadcasting, I'd say with contemporary
equipment, noise is not much of a worry as compared to headroom. Personally,
I think broadcasters use too much compression, but then, the focus is on
simply getting the program across, then okay... A "leveling" like an Aphex
Compellor could help a board operator achieve optimum level settings. A
compressor/limiter can help, but it's an art as to setting it for relative
transparency, low noise and low distortion. :-p

"Broadcast sound quality" used to mean something, but today it is distorted,
squashed, flattened and mushed beond belief.

I did some ads, listened to their playback when broadcast, and modified my
sound from there.

Overly compressing in production is counter productive.

Get your levels up there, but leave some peaks for the station processing to
deal with or else the sound broadcast will be quieter, not louder and punchier.


Some systems will give you required levels, (0dBVU= -20dBFS I personally
find that too low and prefer 0VU=-12dBFS ) some will not.
