New DMG Audio Limiter - Limitless!

[Tp3]

JFI guys... clipper @x64 is mighty CPU hog (that is to be expected, I guess).

On my very old computer (9550) anything above x16 is a no-go.

And if I thought about buying a OCed 6700k, now I seriously think about 5820

Normally you don't need more than x2-x4 oversampling. You could use that in realtime and render in offline mode at higher OS rates.

Yes but how will I know the impact on the sound ?

Anyways, my computer can bare x16 which is satisfactory, I guess.

As time goes on and having read the manual couple of time, me have to say :

I WAS WAITING FOR THE WEIGHTING !

Big big difference with extreme bass heavy material.

Is Limitless at all similar to Ozone's IV limiter? Does it "reduce gain in bands that contribute most to peak levels", or is it merely multiple bands each with a limiter?

Hello Dave ! I have just tried the demo version. Sounds really good after a few tests

Two remarks :

- I use it on Windows 8.1 with Reaper 64 bits. When I want to see the settings, the bottom tab appears, and when the settings tab is closed, the bottom tab diseappears. Is it normal ?
- I think the CPU load for the processing is fine. However, the UI seems to use an insane amount of CPU to display the graphs (around 40 % of my i5 processing power). Would it be possible to optimize it ? I know this is something tricky to do with JUCE

I don't think you'll be able to 'hear' the difference between x4 and x16 oversampling. x4 is already fine quality. x16 or x32 is insane quality for high-end pro mastering work - difference should be discernible only with sophisticated analysis tools.

Limitless is not targeting bedroom producers, you know.

Hi DMG AUDIO,

thank you again for this great tool. I have used Compassions limiter for the imho most transparent limiting
process in the past.
I`m sorry to tell you that it's beaten now
Limitless with a little tilt from Equilibrium and some balancing from Essence (thank you BK) let me focus
better on my music again because it is so fast to improve your bus sound. (I hope the desired results
manifests reliably in the future)
DMG AUDIO ist the king of revealing DSP imho but I wanted the dirty crunchy side for ever from you.
The new Clipper gives it to me surprisingly. Driven too much it sounds really great!
Things similar to this with transient control without latency would also be great

And the UI is great.

I'm on a 2600k with a Gforce 8600 gs I think and this Open GL thing? eats my overall computing power
with 3 displays with 1920x1080. Opening Dualism in Bitwig with about 70 % CPU leads to 100 % and crashes.
Do you have any recommendations for me with this? Win7 64. Thank you.

Do we have a hint in your Videos about your next product? Forensic Audio Analysis?

I don't know if openGL needs so much CPU, for me it's more the linear phase EQs for the bands and the 4x oversampling for the ISP mode. Using only 2 bands and with disabled ISP the CPU usage is comparable to other limiters.
So for very heavy projects which are already at the CPU limit it needs a different workflow (mastering with a different project and leave the 2-buss empty while exporting)

Inspired by a post above I mixed this Open GL topic up with Dualism where it's more of a problem, at least
for me. Back to topic I would say I think Intel integrated graphics are not the best for my setup.

I was asking about a way to display the measurement in LU instead of LUFS or LKFS (like in Nugen VisLM-H). For example in a calibrated plug -23 LUFS = 0 LU (I think you already know that). It's not really important, just a displaying habit that I have, if it's not possible I don't care. After all, Limitless is not a broadcast tool...

On the todo list

Dave.

[DaveGamble]

A question: there is no global oversampling (only for clipping)? Typically I use oversampling more to prevent intersample peaks but it seems this is handled internally with the ISP option? So oversampling is not really needed?

Correct. For accurate peak-limiting (I've spotted a few limiters that oversample and then clip at audio rate ), you MUST process at audio-rate, but you can (very carefully) oversample the sidechain (which is what ISP does).

I have one feature request Host synchronisation option, so if the host is paused/stopped the integrated measurement is reset automatically.

On the todo list.

[DaveGamble]

Dave, is Limitless using some internal oversampling for the limiter? CPU usage is very high (without the clipper) and latency is about 1019 samples, so something I would expect for heavy oversampling?

The latency is from the max lookahead and the bandsplit. Linear phase bandsplit needs latency!

The former.

Yep - I just pop the bottom tab open to make sure there's space for the setup box.

- I think the CPU load for the processing is fine. However, the UI seems to use an insane amount of CPU to display the graphs (around 40 % of my i5 processing power). Would it be possible to optimize it ? I know this is something tricky to do with JUCE

What are your hardware specs? Do you have a graphics card? Wanna join my "debugging OpenGL" party?

Thanks a lot Dave ! Glad I bought Limitless, your commitment is much appreciated and respected.
And thanks for this very deep manual, I'm gonna dig it...

I'm one of those people that's never been satisfied with limiters out there. They all do a great job, but I tend to write densely packed songs with limited headroom out the door, getting them anywhere near loud enough compared to commercial releases ruins the mix every time. Not shabby limiters either, Xeon, Elephant, Pro L. I think I might be selling all those and getting Limitless. (or at leas Xeon and Elephant, Pro L is CPU efficient enough to use on a bus if necessary)

I have the infamous chip Intel HD4600 They are a pain to maintain, since Intel released at one moment buggy drivers which make OpenGL not work anymore. They solved their issue, but third party computer vendors which provide custom versions of the drivers still use the buggy versions, and I can't update my drivers anymore using the Hewlett Packard auto updater if I don't want to lose the OpenGL support

Anyway, my graphics card isn't the best but it works, I am working myself on a spectrum analyzer with JUCE and OpenGL, and I have spent a lot of time with the profiler trying to reduce the CPU load, which involves in short dropping as much as possible drawPath / fillPath and drawImage from the UI code, to use drawVerticalLine instead and the OpenGL textures for example...
