Just tried it with 3.0.4
Works exactly as you describe. No issues.

This is a bug with ruby... Try to reinstall flowstone, or turn manually on every ruby component inside it...

hm ... that seems strange.

I use RUBY very often in my projects. I understand there are issues at times.

I think I've gone through the whole schematic, searching for RUBY modules. Each that I found I reset ON/OFF.
NOTE: None of the RUBY's show any type of error report, but I reset them anyway.

No change in the result unfortunately. I'll keep looking.

Please ... if any other ideas where or what to do, I'd appreciate it. This EBU R128 is a function that I'd like to be able to use in my project ideas.

Thanks again ! Much respect for the level of work you've already put in developing this. Sure hope I can get it working ;)

Hi!! you plan share the OSM?
Your meter look very good.

You know how build Dynamic Range meter?

How can meter true peak?

Dynamic range is just the difference between peak- and rms-level. This document explains an open source standard that is used by almost all of the DR meters: http://www.dynamicrange.de/sites/defaul ... 20ENv3.pdf

True peak is defined as "only a one-sample-width is allowed to have maximum power, with calculating the real maximum by interpolating using 4x oversampling. Unfortunately I only know the theory, but it's up to the stream gurus to show how to reliably do interpolation by oversampling. Basically, every signal value is quadrupled and an interpolation applied to the four that results in a smooth curve between first and last value. (I'm afraid this explanation is so simplified that the gurus will chop my head off now)
