I kind of see the point in having adjustable metering, but the whole point of standard loudness measurements is that they’re standard. If we change integration time it’s no longer conforming to the standard. If anything I’d like to see an alternative BS.1770-1/2/3 reading. I think one of them is pretty much equal to RS128 so it’s really only for backwards compatibility.
But at any rate I think the objection I have is that people will be tempted to mess around with their “loudness” algorithm and risk end up with not loudness, as opposed to simply having non-adjustable measurements that are clearly labeled so everyone knows what they’re looking at.
Know what I mean?
