The Official DRI /R 128/A85 Measurement App from MAAT runs in the background and automatically measures all mandated R 128 parameters, along with official DRi and a host of key metrics that your DAW may not otherwise display. Much more than just a loudness control for commercials, it provides 24-different measurements, including integrated DRi Dynamic Range and PSR, the emerging Sample Peak-to-Short-Term Loudness Ratio, all measurements that are valuable to a music engineer. This is a cross-platform app that works within your DAW on Windows or Mac.
