Well,
I was suspecting that for a long time but now I am convinced that Paris has
a limiter in his outputs !!!!
Yes either the monitor outs or the LR outs have a limiter on its outputs
that does not let anything go beyond that !
I found that -0.7 was a safe margin at the main outs and no matter how hard
I was driving the submixes and seprate cahnnels there were no overs !!
ou can see that on your mix that there is this chopped over waveform !!
Regards,
Dimitrios

Hey Chuck,
How come you offend my findings ?
Have you tried what I tried ?

Here is the conditions of my test.
I am using the spdif out connected to Pulsar Scope spdif in and I am watching
the digital meters of the Paris out.
When using the 0 for Paris outputs there is a occasional digital clip.
When lowering under 0, -0.3 then the digital over goes away.
Now no matter how much you push the submixes into red ,nno matter how hard
you push the indivindual tracks into red the digital clipping never shows
in Pulsar.

Dimitrios

What your describing is no different than if you had a mixer of any kind
and lowered the master fader. Your end output is not clipping even though
you may be clipping at one of many places before that in the signal chain.
That's still not limiting, unless you want to call it that.
Granted, Paris handles this kind of gain staging really well, and is one
of the reasons I still use it.

Dear Rod,
As with analog mixers if you gain up channels you always have to lower your
main output to compensate.
In Paris leaving the out at -0.7 digital (always) no matter what you do with
your music you never clip it.
Your waveform though shows the clipping (cutting the edges of loud peaks),
so to me that sounds like a limiter !

Dimitrios

Or it could simply be digital clipping that's being handled
well by the inputs of the Scope card... does it have a soft-
limit feature?

I found this to be true as well, I mean the sawed off waves if you back down
the master fader when dumping a track

My understanding was that a flat top wav file is an indication of clipping,
not limiting. That doesn't mean that you'll never see flat top wav forms
when going through a limiter, but it means that if you're seeing that, you
need to adjust your limiter. ;o) A limiter is really just a compressor on
a certain setting, so fundamentally what you see should look like a compressor
has hit it, which basically means a nice curved wav file just like what you
started with, only louder, or at least with less dynamics.

For some reason the flat top wav files Paris creates don't sound like the
flat top wav files that other apps create. They don't sound harsh and distorted.
They just sound kinda louder and with some added harmonic richness, not entirely
dissimilar to if you overdrive an analog circuit, which also, especially
with transistors, tends to leave you with a flattish top on your file. This
is not compression/limiting however. It's just a form overdrive which "hurts"
less than other forms.

Functionally it's similar of course. Anything you do to a wav file will change
the original audio, and limiters can easily lose dynamics obviously. Gentle
overdrive can achieve the same end of increasing overall average amplitude
of the signal, but the trade off is different. Basically, with overdrive,
you keep the bulk of the original audio intact but just "completely lose"
some small sections at the peaks. With compression/limiting there is a greater
overall change to the sound (depending on settings and such) but you keep
the peaks intact, albeit at a lower level.

Horses for courses yada yada.

What Paris does isn't a limiter as I understand it, but it can, in effect,
fill the role of a limiter to an extent.

And the reason Chuck doubts your findings is that these claims have been
made previously, and Chuck knows the inner workings of Paris as well as anybody
here. He's looked through the internals of Paris code and can't see a limiter
anywhere. Unless there is a separate limiter hidden on the EDS card which
doesn't use any actual code from the Paris app, he's right. ;o) I'm pretty
sure he is, in fact, right. :o)

Cheers,
Kim.

But...from my observations, if you look at a compressed wave file that has
been compressed to say -.07dbfs, as an overall file, it will look like it's
been severely clipped.
If you go into sample level, you'll find that all the waveforms are nicely
rounded.
Don't forget, waveform graphics are just approximations, especially if your
viewing a large file as a whole.

Your right Martin. Have you ever noticed that a clipped looking mix in Paris
(in the destructive editor) doesn't look nearly as clipped, or even clipped
at all, if you look at it in another app, like Wavelab. Good point
