Loudness Webinar Recording Available

If you missed Saturday’s webinar, the recording is now available. Just click here to load it up.

We had some reports of audio issues, which appear to be due to the service’s compression settings. All of the truly pertinent information is included in the slides that were part of the presentation. So if things get a little difficult to make out sonically, don’t fear that you’re missing out on important data. We’re looking into how we can correct this for future presentations.

At the end of the presentation, I put up a set of URLs. I’m including them here for your convenience:

Listening Examples – A set of 150Hz and 2500Hz sine waves, and pink noise files…normalized using different metering standards (RMS, LeqA and BS.1770). Just right-click and download.

ITU-R BS.1770 – Documents outlining the metering spec

EBU-R128 – The European broadcast recommendation

ATSC-RP A/85 – The broadcast recommendation from the United States

C.A.L.M. Act – Information about the legislation passed in the U.S. regulating commercial advertisement loudness

And, as I said at the end of the webinar, feel free to e-mail me if you have questions or need clarification on anything covered in the webinar. Or better yet, leave a comment below for me to respond to. That way we can avoid repeats of the same questions.

Free “Loudness Metering” Webinar

We’re changing the name of the “Film Sound Discussion Group” to Designing Sound Discussion Group, because it’s silly to think that we’ll never have a live discussion about anything other than film. While I’m on the subject, it’s also high time we scheduled the next webchat!

As the title of the post suggests, in the next presentation I’ll be explaining how, exactly, ITU-R BS.1770 compliant metering methods work, and the standards and applications that have been developed to make use of “loudness” metering. We’ve already mentioned that February is going to be “loudness” month (bottom of the post), and we’re setting up the first full week to make sure everyone can get a strong grasp of what it all means, even if you’ve never explored the subject before. We’ll be capping  the week off with this webinar on Saturday, February 9th, at 11AM (U.S. Eastern Standard Time).

I’m trying to make this presentation as accessible as possible. Don’t worry though, there will definitely be time at the end of the webinar for questions. If you can’t make the webinar, a recording will be available within the following few days.
