    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?

    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,
    internet delivery
    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.

    I mix my live-to-air shows at -18 - -15dbFS.

    I am working with internet delivery. Is there anything else you might suggest? Thanks for the info.

    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 ?

    Have a listen...

    click the 'listen' button under the post for podcast no. 21. I make reference to this issue during the cast, and I inquired here at the forum for some other opinions. I am being bombarded with inquiries in reference to how I aquire my audio quality.

    You can email me from my site.

    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
    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 ?
