What about the Sonnox Oxford Limiter?

I have this, but it's pretty far behind the list you had in the other thread. I think your money would be better spent on their Inflator! THAT I cannot live without.

All DMG plugs have been updated recently

Yeah - the latest Limitless has a new option in the Advanced section of the Setup menu: "Inter-Sample Peaks: Use ITU filter".

But I can't find any info on what exactly it does. Is it just regular oversampling to catch ISPs?

I was wondering about the High Pass Filter in Limitless.

So I checked the manual and it's described as "a regular minimum phase coincident-pole design". So it's minimum phase.

Wouldn't it therefore be more ideal to disable the HPF in Limitless and instead use an instance of Pro-Q2 before LImitless with a 'Natural Phase' HPF?

I guess my qustion is... Limitless HPF vs Pro-Q2 HPF? Is minimum phase most ideal for low end cuts?

Does anyone know if the Limitless HPF is applied at the input or output?

It is there primarily as a DC offset remover, so it is first.

If it were last, it would redistribute peaks and cause all kinds of issues with the post limited waveform and ISPs etc.

Edit: p.s. Minimum phase for low cuts always. Pro-q natural phase has pre ringing, so is anything but natural ironically!

Thanks! But what of the phase shift?

DMG replied - the HPF is between the clipper and the limiter. Makes sense!

You usually want to use a minimum phase filter for high pass filtering, because anything other than that will sound bad. No real technical idea why, but that's just my experience. I never use the HPF in Limitless because if I apply a HPF at all in mastering, it's either before the analogue chain (with Slick EQ M), or at the end of the analogue chain (Dangerous Bax EQ) right before the ADC. Not to mention all the transformers completely remove any DC anyway.

But yeah, Dave really needs to get some info out there on all the new tweaks/features, or update the manual etc. The ITU filter goes CRAZY amounts of GR when activated, what would normally be around 5-6dB GR can be as much as 20dB with the ITU filter activated, also takes more CPU, so I never use it.

Yeah I'm finding this aswell. I had it activated and I was scratching my head all day today trying to find the source of some nasty clipping sounds (though not actual peaking) that was happening in this track. The mix is sounding amazing except for just a couple of spots where this weird, nasty click happens on just a couple of transients. I checked Limitless and it didn't look like the cause because backing off the Threshold etc didn't fix it. After an exhaustive search I found myself back rummaging around in Limitless and lo and behold the ugly click disappeared as soon as I disabled the ITU. Hmmmmmm why did I leave that on

I can confirm what you guys are reporting about the ITU filter.
Unusable at present, unless there is something we don't know - that an updated manual might tell us.
I've emailed Dave.

why is AVG antivirus flagging the latest Limitless installer?

You can have a ceiling of -0.20db and with the ITU filter engaged you literally get a file true peaking at -0.20 or -0.19. So what the ITU filter does do is prevents ISPs very, very effectively - unfortunately with some trade-off artifacts of its own if pushed, which is a shame. Might be great on softer material? But then you probably wouldn't use heavy limiting anyway.

In my testing this weekend I've now disabled the ITU and it's cleaned this track up a bit, but now ISPs are getting through when I export to MP3. Hmmmm - how to avoid? Don't want to use the clipper so might just have to lower the ceiling onlyfor the MP3 versions. The 24-bit master is fine though.

Is there a Wave-to-MP3 convertor that catches ISPs?
