Hi all,

I'm new to this and like 1manband I'm also trying to understand Peak & RMS.

Firstly, can I clarify. Are you saying that the RMS figure is calculated by applying the corrected formula (sorry Andreas!) to a rolling window of the "Peak" (ie actual dbFS) signal.

Assuming that's so, I did a few very simple calculations on a bit of paper based on the said formula and, correct me if I'm wrong:-

1. A completely steady signal would yield a figure for RMS that was the same as Peak whereas,

2. A mixed level signal would give (unsurprisingly) a lower figure for RMS than that of Peak.

I've two reasons for wanting clarify this:-

1. I need to know (as my wife will tell you - lol) and I know it will help me, and

2. When I did the "steady signal" experiment in practice with my DAW there was around a 7db difference between RMS & Peak.

Thanks

Mike
