Before asking question regarding 0 dBr, I need to know more about the levels display used under FM.

What does these three different colors means?

Edit: If the image doesn't work, here is the link https://minfil.org/xwycoUkt352SX8JlpPE3 ... levels.gif

"In the graph, you can see lines of different colors: BLACK shows the moving BS412 output level and should be below, but as close as possible to, the 0 dB line. RED shows slow volume changes. In general, it's best if this line doesn't drop below -1 dB - bigger drops can be noticeable. GREEN/PINK shows short-term volume drops caused by the compressor. YELLOW spikes show that the de-esser reduced loud highs. The actual drop of the highs is less than what is depicted here. BROWN spikes show the de-basser in action."

Ow. White = measured level. Light gray (actually, dotted) = going up in the first minute because it takes 1 minute before you have an accurate number (since the spec says it needs to be calculated over a 1 minute period).
