I produce a broadcast piece. It is spoken word, recorded with a Mackie, a Shure SM7B, Compressor and Motu's DP with an 896HD.



Is -12db normal and -6db peaks the proper, or accetable set of rules for recording/outputting for broadcast audio?



thanks.

more like -18 or -20dB FS



A test CD may be of use to you.

Some CDs have more than just test tones and a spoken word track at the Broadcast standard could be a good learning tool for you.



Be aware that there seems to be a couple of Broadcast standards and growing

and you need to specify which one you are aiming at,

NAB

EU

internet delivery

DVD

and so on



big subject



Bob Katz has a web site that helps a little here.

Also the manufacturers have data in there instruction books that both help and confuse.

TC electronics have units like the TC-Max and I think you can download the manual. This can also be of use to try to understand where the various theroies come from.



Yes I can here all the crys of the old fellows BUT the fact is we now live in a far more diverse broadcast world and the old rule are constantly being broken.



The BBC will probably have a very old view on things if you want to get back to basics of transmitter over-deviation.



I have some pages with level data but, if you can believe this , I can't remember where I uploaded them ... here at RO or at my new place.

silly me

I'll see what I can find.

If we are just concerntrating on the internet delivery then some of the hardcore Broadcast standards aimed at Transmitters ... both analog and digital can be set aside.



I still suggest you get your hands on that TC-Max handbook to read up on a little background.



Is this internet streaming going to be edited stuff or is it streamed live ?

Yes the Ozone plug and these MultiBand Dynamic and EQ mastering tools have been mentioned here before.



I'll take a look at that 'listen' button when I get home on the weekend

BUT

I warn you that my net is slow and don't expect to be able to complete the process.



... yes I'll look to your web site for the email.



I do like to do things in the forum or on a web page so others can look in too.



I have a web page in development that looks at these issues.



The OLD broadcast levels were about analog transmitters and deviation.

Over deviation is NOT on.



Do I need to explain any of this history or should we just head straight to streaming ?
