Loudness Meter [v1.2.1]

Post by Logickin λ »

Worrying about the tracks being compressed too much, result in being punished by the all the famous streaming platform and social media?
Don't know about how much the song should be compressed to balance both dynamic range and loudness?

Now we have a solution!
Working with fuzion_mixer, introducing the Loudness meter!

This meter offers the following functions:
- Shows the dynamics of your project
- Measures the average loudness of a section of your project
- Records the maximum loudness of the project
- Analyze both channel at once, or only track either left or right channel within 2 clicks
- Panic button for reset the module for a rarely occurred stuck state

How to use the module:
1. load your song as a module for existing project, or add a "master" amplifier which connects to the output and the loudness meter for a total new project

2. Set the Vol. to 100% , to get the most accurate result

3. Set the visualization for the loudness meter as the following:
Level Meter: Stereo
Lever orientation: Horizontal
Level scale: Logarithmic (dB)
Peak meter: Level + Value
Oscilloscope: Line / Bars

4. Play the project, the meter will track the loudness for you! The left channel tracks the dynamic range of your song. More bouncy it gets, more dynamics range to your song; the right channel tracks the short terms loudness of your song, with the error of ±1dB at the worst case, compared with the YouLean Loudness Meter 2:

5. If you want to see the maximum loudness ever recorded for the project, set the "Left Channel Display: Dynamics / Max Loudness" to "On"

6. To clear the maximum Loudness or resolve the stuck state of the module, you may switch the "Panic" button On and Off, or simply double click the stop button.

There are some limitations, and it has no solution so far:
- No "integrated Loudness", since it will introduced unbearable amount of delay due to the smoothing parameters.
- No True Peak, since it requires over-sampling which is not possible at this point
- The Loudness meter may has a second or two latency due the the smoothing function.

Here is the module: Have fun! Please comment down below if there are some questions.
I was stressed out by my own matter, but I am finally back on the SunVox discord.

amazing! now i don't have to use an external meter to track the dynamics of my songs :)

this is fine, i prefer to use short term lufs anyway, gives me a sense of which sections are loud and quiet

hey, i have a suggestion

the klangfreund lufs meter is open-source: https://github.com/klangfreund/LUFSMeter

i'm sure you can look at that and make improvements on this module if you want to

interesting! thanks for this!
Which values (numbers) do you recommend as a rule of thumb?

Thank you! I don't notice there is an open source one. We would definitely go to check this out in future.
Not only this may improve the module, but also the knowledge for vst plugin written in C++!

You may take a reference to this site:
https://www.masteringthemix.com/blogs/l ... nd-youtube

TLDR; keep the loudness for some of the major platforms:

Code: Select all

Spotify     : -13 to -15 LUFS
YouTube     : -13 to -15 LUFS
Soundcloud  : -8 to -13 LUFS 
Apple Music : -16 LUFS (±1.0 LU) 
If you set your module to display dB, 1 Lu is exactly 1dB.
