MAAT will not only maintain the DRMeter in the future but also improve it into an evolved fully ITU BS.1770 (R128/A-85) compatible universal metering tool (DRMeter MkII). Release is scheduled before end of 2017.
presumably due to noise
FWIW, R128 seems to have a pretty serious issue as well:https://hydrogenaud.io/index.php/topic,110561.msg911014.html#msg911014
I find that David Robinson's original algorithm does a better job. R128 exaggerates the loudness of modern mastering; for metal at the very least.
