Goodhertz launches free loudness analyzer 'LOUDNESS'

Goodhertz has released a free loudness analyzer plug-in, 'Loudness'. This plugin is part of the Goodhertz Free Series (which means it’s completely free).

Why is this better than my DAW volume control or trim?

It sounds better.

This might sound like marketing hyperbole: how can a digital volume control possibly sound different?! But in a number of measurable ways, digital volume controls are imperfect and are often poorly implemented. A quick example: a simple sine tone faded out with a standard DAW trim plugin vs Goodhertz Loudness: The stock trim plugin is full of tiny digital clicks — small discontinuities in the audio — almost like a scratchy potentiometer but digital. Loudness, on the other hand, is completely clean. Nearly every DAW we tested caused clicks & pops when automating Mute, Solo, Polarity, or Mono Summing switches — all of which are performed clicklessly in Loudness. With fully 64-bit processing throughout, you can trust that Loudness is the finest volume control available: no clicks, pops, or added distortion — just clean, smooth volume ramping.

It has really nice metering.

With LUFS, RMS, Peak, & True Peak meters and three different time windows (Momentary, Short, & Long Term), you’ll always know exactly what’s happening in your track (and what’s already happened). Fader rides are quicker & easier because you can easily see where things might need adjustment. The Summary page provides a comprehensive numeric summary of all metering types simultaneously and can easily be copied to clipboard to share with collaborators, added to a track log, etc.

Advanced options help you work faster.

Customizable fader glide times allow you to spend less time smoothing automation points manually — let Loudness take care of it for you! Up and down glide times can be set separately, which can be useful for manually automating drum hits, etc.

It helps you hit the target.

Set a target loudness level, hit “Apply,” and the fader snaps to the correct position, taking the guesswork (and the calculator) out of hitting a target reference level. Open up the advanced page and hit “Apply Balance” and Loudness automatically adjusts the fine trims to perfectly balance the stereo field.

It has extensive stereo controls & metering.

Mono Sum, Solo, Mute, Polarity, Fine Trim — they’re all available in the advanced pane. Loudness can be downloaded from the Goodhertz website. Read the full article

Dialog-gated Audio loudness and why it is important

Being a fan of watching video content on a variety of devices, I sometimes get into situations where I can’t make out what is being spoken even though the overall audio levels are fine. Have you experienced these issues? I am sure they are annoying enough and make us think how this content was approved for publishing with such obvious issues.

Many of you would be surprised that such content can pass the Loudness criteria that are commonly used for typical audio QC testing, and if not manually reviewed, the content can indeed pass and be made available to consumers. This is because a more sophisticated level of Loudness testing, called ‘dialog-gated loudness’ criteria must be used in order to verify that the portion of the content with dialog has the proper loudness levels. Not performing the dialog-gated loudness verification could result in content that while passing general Loudness criteria, may still not have audible dialogs for the viewer. This can negatively impact content providers who are continuously vying to gain & retain consumers by maintaining the high quality of their content – both technically and editorially. Now a days OTT service providers like Netflix and others require the dialog-gated loudness compliance.

In this article, we will discuss how such issues can be detected by using Dialog-gating and how our QC products can help content providers achieve this in a fully automated manner.

Dialog Gating

Gating is the process that only pass audio signal satisfying the criteria while removing the unwanted audio signals from loudness measurement. The gating criteria may be absolute audio level, relative audio level or audio type such as speech or non-speech.

Dialog-gating is a process that only allows the audio signal which has speech content. All other non-speech audio segments are rejected and not passed through for the loudness measurement.

Level-gating is a process that only allows the audio signal higher than particular audio level to pass through. There are two common level gating techniques:

Absolute Gate. All the audio segments below a particular audio level (mostly -70 LKFS/LUFS) are rejected.

Relative Gate. All the audio segments that are lower than particular value (mostly 10 LU) below the average absolute loudness are rejected.

Let’s consider the case of a 5.1 audio stream. The list of channels in such audio stream are L, R, C, Ls, Rs, Lfe. Normally the speech content is carried in the Center (C) channel but sometimes it may be carried in Left (L) and Right (R) channels also. For this reason, only L, R and C are considered for calculating the Dialog-gated loudness and all other channels are ignored.

In real workflows requiring dialog-gated loudness measurement, an adaptive gating approach is taken. It means that Dialog-gated measurement should be performed if there is sufficient speech content in audio. If the speech content is not sufficient, then level gating is used to perform the loudness measurement.

The diagram below shows such a workflow for a 5.1 audio stream:

The upper half of this diagram takes the audio content from L, R and C channels for dialog-gated loudness measurement. The content is passed through “Dialogue Intelligence” to determine if the audio contains speech. If the audio has speech, it is assigned a gain of one, else zero. The resultant channels with gain are fed to the dialog gating process. In this case, only the audio segments containing speech will pass through along with corresponding loudness level and amount of speech content. Non-speech audio segments will be dropped. Adaptive gate selection decides whether to use dialog gated loudness or level gated loudness depending on the overall amount of speech content.

This measurement provides a true picture of actual speech levels in audio and content providers can be sure that the audio experience of their audience is preserved.

Venera’s Automated QC tools – Pulsar™ & Quasar® allows automated measurement of dialog-gated loudness measurement. Following options – shown for the EBU mode (popular standard in Europe) – are available in both the solutions:

These options are available for ATSC (popular standard in North America), OP-59 (popular standard in Australia), and ARIB TR-B32 (popular standard in Japan) modes as well.

In addition to measuring the dialog-gated loudness, users can also measure the difference of loudness level using dialog-gated measurement and level-gated measurement. This gives them a practical perspective of audio composition in the content they provide to their consumers.

Pulsar™ also allows users to automatically normalize the audio levels eliminating manual intervention in making the content compliant.

In addition to Loudness measurement, Venera’s QC tools – Quasar® & Pulsar™, offer a wide range of Audio and Video measurements that help users automate the otherwise tedious content QC operations.

Quasar® is a Native Cloud Content QC service, allowing auto scaling with ability to process hundreds of files simultaneously with wide range of content security capabilities so that our users can process their content with peace of mind.

1,2,3,4,5,10,11,12,13,15,21,24,25 and 30 for the end of the year fanfiction asks please bb!

1.favorite fic you wrote this year

AAAAAAH this one is hard honestly bc I did branch out this year to do fics I never thought I would. Rn I’d say Don’t Fear the Reaper and The Wolf & The Mad Dog bc those are 2 I never saw myself doing. I always write for Daryl and I luf him but I took a risk branching out a bit to shows I love but thought I wasn’t talented enough to write for.

2.least favorite fic you wrote this year

I don’t think I really have a least favorite? This year I feel like my writing has been so much better. I think part of the reason is bc I made this blog and have been committing myself to writing more than I ever have. I never thought I’d make a fanfic blog tbh. At times in chapters I feel meh about them but overall this year feels like it’s been on point.

3.favorite line/scene you wrote this year

Omg I’m blanking. The first one that comes to mind is Taylor’s trauma/revenge in Right Before Our Eyes. I feel like writing smut is hard and writing traumatic things is also hard. I seem to have a skill in writing fucked up shit. I’ve been told by you that I made you cry before. So that scene in particular and any kind of scenes that made anyone cry,laugh or anything else etc. I’m all about the emotional response.

4.total number of words you wrote this year

I dunno how to calculate that since I only JUST started writing in my google docs. I used to just write up a draft on here lmao. I’m gonna say 2304848994203920 words. Thank you.

5.most popular fic this year

So I was BANKING on one of my Daryl series to be the most popular...it isn’t. They actually are doing shit. My most popular fic this year is...The Wolf & The Mad Dog. I did not expect that. The highest note being 51 I think. Damn.

10.shortest wip of the year

....My Hangman series I keep swearing is coming. I just hit a brick wall with that one and i’msofuckingsorry.

11.fandom you enjoyed writing for the most this year

All of em? I really can’t choose tbh.

12.favorite character to write about this year

...I’m supposed to choose one? Just one? Like 1? -cries- Ok. I am gonna give 3 answers. Hangman,Ramsay and Chibs. Hangman bc @robwiethoff made me fall in love with him 100%herfault and he’s such a sweetie. Ramsay bc he poses new challenges since he’s such a sadistic prick. Chibs bc...it’s Chibs. I don’t need to explain to you.

13.favorite writing song/artist/album of this year

Ice Nine Kills definitely inspired me with their metalcore music. Your Number’s Up which is about Scream actually made me wanna go forward with my modern!Ramsay au. Music always helps me get the mood of what I’m writing.

15.something you learned this year

To not be afraid. To just go for it and even if you write it just for you or the one other friend who loves it then so be it.

21.most memorable comment/review

Every single one? Your comments in particular always get me. Especially bc you’ll be very specific on something you love. Overall tho I love any feed back from friends or even complete strangers. It makes my fuckin day. The most memorable for me is when I made you cry. If I get an emotional response whether it’s crying,laughter or even anger that just makes me so fucking happy.

24.favorite fic you read this year

ALL OF THEM. Most recently Hot Chocolate Mustache bc it’s such a fucking honor for someone to take my OC and their partner and write something for me essentially bc they love the pairing. Probably the biggest compliment I could get. Anything that also includes me/Claudia in their works. It warms my heart to be made into a character essentially. @doedreamss Some Real Cowboy Shit makin me drool on my laptop. A Little Country Christmas from @sassbei that I kinda had a hand in making happen but all cred goes to her for writing it. @moxleysbaby Why? makin me cry like a lil bitch. Lingerie from @robwiethoff. Golden Cage by @twdeadfanfic is so good. I’m behind a few chapters but pls give it a look it’s so so so so so good andi’manassholeforfallingbehind

25.a fic you read this year you would recommend everyone read

See number 24 bc I threw a lot in there. I have a section on my tumblr called Rampage Fic Rec which is exactly what you think it is.

30.favorite fandom to read fic from this year

AEW,Sons of Anarchy,WWE,Game of Thrones,TWD and pretty much any other show I love. All day every year.
