How do you know a master is clipping...

Well for example I often read "I achieved -9 dbRMS without clipping". And I realize while I listen to test sounds I do, that if I put a strong limiter, it clips a little. Or maybe with the trick to limit to -0.3 or -0.1 dBFS it permit extreme stupid brickwalling with no clipping, technically speaking ?
 
But on the other hand, I know there were tons of albums I couldn't hear clipping on until I got my Tannoys, so I wouldn't wanna trust that too much!
 
fuckin' a, just export the track, load it back into the DAW, and look at the waveform. if it's shaped like the arizona skyline, it's probably clipped.
 
"I achieved -9 dbRMS without clipping"

I think Joey Sturgis started a thread titled "I achieved -7 dbRMS without clipping" where he was referring to not using a clipper like G-Clip in the mastering chain. That's probably what most people from this board mean when they say they achieved a certain level without clipping. Beyond that, using your ears is your best bet. You'll hear it when it happens.

i was under the impression that it meant more "i achieved -7 db RMS without the clip indicator lighting up on the master buss"

aka the mix got compressed/limited/g-clipped to death, but didn't peak over 0dbfs

Also, doesn't seem particularly hard tbh. Whether it sounss any good is an entirely different matter.
 
Ozone is a clipper.............
Basically achieving something hotter than -10db RMS and still make it sound musical and as true to the mix as possible will ALWAYS mean some kind of clipping is involved. Having said that, any album hotter than -10, which is to say most of them, will have some kind of clipping going on, so you don't need to look for it really. :)
 
Can you explain me exactly the basics of a clipper in comparison to a limiter and how to use it ? For example I don't see the interest of the clipping knob on GClip ? Don't get it.
 
It's pretty basic - a limiter detects when a signal goes above a certain threshold (which you set) and then brutally yanks it back to be beneath that (hence the term "brickwalling", cuz it's as if the spikes are hitting a brick wall), whereas a clipper just cuts the tops off of those spikes, which can be bad on things like guitars, vocals, etc., but very very very good on anything with super sharp transients where we barely notice anyway (especially snares). So the philosophy is: since snares usually create sound spikes higher than any other instrument in a mix, they strain the limiter because it has to work to bring them back down, but since it's only working on the master bus, the rest of the mix suffers as well. However, if you clip the snare using something such as GClip, then it doesn't spike nearly as highly, and you can bring the volume up much louder with the limiter before it starts sounding horrendous because it's not working as hard to tame all those crazy snare spikes.

Hope that helps! :)
