born_hard Posted February 12, 2012 Share Posted February 12, 2012 hi, lots of help here on the forum. thanks I have following problem :I have the limiter engaged in the stereo out (master) channel, but i get clipping (i can see it about +5 dB). but cant hear it. Whats wrong? Thanks Quote Link to comment Share on other sites More sharing options...
triplets Posted February 12, 2012 Share Posted February 12, 2012 Can you post a screenshot of your limiter settings? Quote Link to comment Share on other sites More sharing options...
Rev. Juda Sleaze Posted February 12, 2012 Share Posted February 12, 2012 Also check that your stereo-out and master fader are both at 0.0dBFS. Quote Link to comment Share on other sites More sharing options...
born_hard Posted February 12, 2012 Author Share Posted February 12, 2012 I dont get it. Everything seems just fine with the limiter settings and all level settings. in the limiter itself it does not overshoot -0,1dbfs , BUT in the channel fader itself in the display itm pekas around 4 db. Its also curious that i cant here digital clipping ! Look in the attachement please! Quote Link to comment Share on other sites More sharing options...
Eric Cardenas Posted February 12, 2012 Share Posted February 12, 2012 Your Master fader is at +6 dB I edited your post with the actual image instead of the zipped file. Quote Link to comment Share on other sites More sharing options...
triplets Posted February 12, 2012 Share Posted February 12, 2012 Like Eric points out, it's clipping because of your Master Fader. Option-click the fader to bring it back to zero. Never touch that one. Always leave it on zero. Quote Link to comment Share on other sites More sharing options...
Eric Cardenas Posted February 12, 2012 Share Posted February 12, 2012 Option-click the fader to bring it back to zero. Or just click the little speaker icon at the bottom all the way to the right. The other speaker button lowers the master fader to its "Dim" value. Quote Link to comment Share on other sites More sharing options...
Eriksimon Posted February 13, 2012 Share Posted February 13, 2012 But still, guys, that master fader setting cannot be responsible for the + 4.2 reading on the stereo out channel strip, and I believe that was the question...? Or can it? Is the Master fader actually before the Stereo Output in the signal flow...? OK, need to verify that I guess... as per Triplets advice, I never touch the Mster fader, so I'm not sure where it sits in the signal chain... I'd expect it to be the very last, so that it doen not alter the Stereo Output level meter... OK, well, I checked, and indeed altering the master fader alters the Stereo Output levels, so the master fader is actually situated before the Stereo Out in the signal chain... good to know, for future reference... but confusing nonetheless...

Eric Cardenas Posted February 13, 2012 Share Posted February 13, 2012 The master fader works as a VCA fader and controls all your Logic outputs together, essential for multi output surround. Quote Link to comment Share on other sites More sharing options...
Eriksimon Posted February 13, 2012 Share Posted February 13, 2012 Ah, OK... but though I do know what a VCA is, I'm not sure what a VCA fader is... ok, Google... I think I get it now.* The master fader sort "goes over the head" of all other faders and directly reduces or multiplies all output signals in the "main amplifier". so it is not really "in" the signal chain, but "over" the signal chain... and that makes it crystal clear as to why it is essential for multi output surround.

David Nahmani Posted February 13, 2012 Share Posted February 13, 2012 But still, guys, that master fader setting cannot be responsible for the + 4.2 reading on the stereo out channel strip, and I believe that was the question...? Or can it? Is the Master fader actually before the Stereo Output in the signal flow...? Yes, the master fader is responsible for the + 4.2 on the Stereo Output Channel Strip. The master fader channel strip is not really a channel strip like the others: when working in stereo, no audio flows through the master fader. The MF simply applies an offset on the gain applied by the faders on ALL output channel strips. Example: Stereo Output fader set to 0 dB Master fader set to +6 dB ... is the equivalent of... Stereo Output fader set to +6 dB Master fader set to 0 dB Gain applied at the output of any output channel strip = Gain applied by the fader on that channel strip + Gain applied by the master fader Hope that helps.

Jonas Fonn Posted March 20 Share Posted March 20 Hey all, digging up an old topic here, because I'm having a similar issue which is not caused by the solution in this thread (although that's definitely happened to me before as well). Nothing is clipping without the adaptive limiter on the stereo bus, but as soon as I add it with some gain, we get clipping during the snare hits, even if the Out ceiling is set as low as -1dB. What are some alternative probable causes of this issue? Quote Link to comment Share on other sites More sharing options...
fusbur Posted March 20 Share Posted March 20 This might help. You have 2.2db of gain on the limiter. I suggest you try putting the gain plug-in before the limiter to bring the level up or down to around -6dBFS then ad the limiter. Quote Link to comment Share on other sites More sharing options...

What are some alternative probable causes of this issue? You have Input Monitoring buttons turned on. The clipping you're seeing on the Stereo Out is likely produced by that signal coming from those live inputs. Disable both "I" buttons on those two channel strips.

Jonas Fonn Posted March 20 Share Posted March 20 Thanks, but I think I (kind of) found out what was causing the clipping: Low latency mode was on. Now, why that would cause clipping I'm not sure of, but I guess some real-time processing in the adaptive limiter was disabled. Quote Link to comment Share on other sites More sharing options...

Yes, the tracks that are input-monitored were not going through the Adaptive Limiter, to avoid them adding latency. Quote Link to comment Share on other sites More sharing options...

You're right, after turning input monitoring off on those tracks while low-latency mode remained on, there was no more clipping. I still don't understand why this would cause clipping even when I wasn't playing those input-monitored instruments during playback, but I'm happy to get the gist of it. Thanks!

When the Input Monitoring button is engaged, you're summing both the live input and the audio regions on that track and routing that signal to the Stereo Out. Because you're in Low Latency mode, that audio signal (the sum of input + audio regions) is not routed through the adaptive limiter, which would otherwise add latency.
