Hi All,

Thanks for taking the time to read this discussion.  This is my first post ever to this forum.  I just need an opinion on the Loudness Radar to see if my project audio is OK.   The project is a documentary with dialogue, backing music and narration also occasional SFX.

Here is the issue.  I mixed the levels in the sequence so everything sounded/blended perfectly and fell within the -24 LKFS range.  When I look at the Loudness Radar over a 1 Min speed scale there was absolutely no peaking into the yellow, everything was green or below.   I then set the Radar Speed to 2 hours and let the entire sequence run for the 1 hour 20 mins of the film and low and behold I started seeing slight yellow peaks everywhere on the edge of the radar.  When the sequenced finished the overall reading was -26.9 LKFS.  (failed to comply with the -24).  So it would indicate to me my mix was slightly to low to pass.

I then raised the level of each track in the mixer by 1.5 db, everything still sounded fine in relation to each other.  I ran the entire sequence again, this time the yellow peaks were more defined but I got an acceptable score of -25.4 LKFS.  (see attached image)

What I want to know is although it appears to fall within the allowed range are you allowed to have yellow peaks?.  I was under the understanding that Yellow peaks were not good.  Does my radar image look OK to pass?  or is there something of concern?  Any comments or suggestions would be appreciated.  Thanks.

Yellow peaks are fine.  The Program Loudness measures the average over the entire program.  So long as that is on target, you're good.

The exception is if the Peak indicator is lighting up.  Those are "illegal".  You don't look to have any of those.

In the UK, ITV expects a loudness of -23 with the maximum peaks of any clip to be -2dbfs
