The EBU R128 filter is very useful.
An extra feature that would useful is the evaluation of True Peak.
I'm not skilled enough to assist with implementation.
The steps are explained in the spec in the last Annex 2 at:
Basically 4x over sampling needs to occur by placing 0's between the samples, then a low-pass "interpoloation" filter needs to occur to remove the high frequency noise created in the over sampling process, then the true peak values can be retrieved.
(this is a guess)
