EBU R128 Loudness Measurement JSFX

[TBProAudio]

Hi,

so finally I did it during a rainy day: the EBU R128 JSFX library (+ small test script)

You will get:

- all in one EBR128 Loudness Measurement Class
- passes all stereo sample files from "EBU Loudness test set - v03 - 15 Sep 2011" including multichannel
- including class for prefiltering according ITU Filter settings
- including class for measuring Momentary/Shortterm Loudness
- including class for measuring Integrated Loudness (currently 1 hour max)
- including class for measuring Loudness Range (currently 1 hour max)
- including class for measuring TruePeak based on BSpline Interpolation (4xOverSampling)

... and as a goody a small memory manager class, qsort and bspline functions

Of course the library is far from being perfect and highly optimized, some stuff is simply left for debugging purpose:-)

So feel free to use it and let me know what you think. (corrections are always welcome)

And finally please download EBU R128 JSFX here (Pls. scroll down)

F yeah!

I'm going to work on a GUI for this.

Amazing work! I'm currently in the middle of moving, but I'll give it a try when I get settled down.

Cheers!

Wow, this is good, thanks Thomas!

Speaking about the GUI, a slightly related question to James; any possibility of having the slider values shown as separate meters also? Not saying they necessarily should, just fmi.
