Werner Althaus Posted October 30, 2015 Report Share Posted October 30, 2015 Just wondering about how to handle the 60 seconds of tone (-20dBFS/ roughly -20LKFS) and 30 sec of silence before the program starts when measuring/ correcting loudness to a target value of -24LKFS. The 1770-3 standard gates for silence but doesn't ignore tone so the integrated loudness will be skewed by that tone if included in the file to be measured/ corrected. I'm mixing close to -24LKFS by ear, doing what I've always done but I want to include a render for loudness to get as accurate as possible using RX5's loudness tool. If I include tone in the file (like I always did in the past) it'll turn down the audio because there's 1 minute of "content" (tone) that is 4 dB too loud over time, not good. On the other hand, the guys doing the layback want tone included in the file. There has to be a standard way of dealing with this by now. Thoughts?

John Blankenship Posted October 30, 2015 Report Share Posted October 30, 2015 Good question. One option would be to include tone in a separate file. Another would be an abbreviated section of tone -- after all, digital lineup is quicker, and looping a section much easier, than things were in the linear tape days. Maybe do both: 60 seconds of tone in a separate file, and 5 to 10 seconds at the head of the program, accompanied by a brief explanation.

Wandering Ear Posted October 30, 2015 Report Share Posted October 30, 2015 Could you measure the file first, then prepend the tone after? Quote Link to comment Share on other sites More sharing options...
