message: dBov or dBO is another measurement in decibels related to the overload level.  Is this similar enough that we can cover them in the same article? — Omegatron 21:00, 16 March 2007 (UTC)
replies: text: (edit conflict) To be honest, the decibel system is the logarithmic measuring system of signals compared to some reference.  dBov, dBfs, etc. are just different ways of specifying what the reference is.  They should probably all be merged with and redirected to decibel. --Selket Talk 21:15, 16 March 2007 (UTC)
replies: text:  Decibel is a huge article that needs to be split.  It already has summaries of each of the units, but many have enough detail to merit their own articles.  dBFS, dBov, dBO are all essentially the same thing, though.  — Omegatron 23:43, 16 March 2007 (UTC)

message: Could someone please explain the difference between dBFS and Full scale?  Are they the same thing?  Should they be merged?

replies: text: "Full scale" includes analog signals while "dBFS" does not. Inclusion of the other topic in "See Also" is probably enough. Binksternet (talk) 02:11, 31 December 2007 (UTC)
thread_title:  dBFS vs full scale 

message: Is this statement correct? If the reference value is L, 50% of maximum level will be 0.5L, so the level will be: 10log(0.5L/L) = 10log(0.5) = -3.01 (approx).
Am I right?  —Preceding unsigned comment added by 203.161.71.242 (talk) 11:29, 24 May 2010 (UTC)
replies: text: You are getting -3.01 because you are using a natural logarithm instead of a base 10 logarithm, but that statement is still poorly explained. The varying conventions mean that a measurement in dBFS can't be as abstract as the example implies. If the example signal is arbitrary and the convention is unknown, then you can't say accurately that the highest peak will be at -6dBFS. "Maximum level" doesn't mean anything.

replies: text: Actually, my bad. The log button on the calculator I used did not label the base and I assumed that meant base e. That is what I get for blindly punching numbers in and not reading the documentation. In any case, power = coefficient of 10, amplitude = coefficient of 20. RMS is still a measure of amplitude, and still uses 20. My observation is that level is not a technical term and peak is not a generality. They are really only put together on meters, and most meters only tell you half of what they are actually doing. Radiodef (talk) 01:33, 10 November 2012 (UTC)
replies: text: You're using a power equation. The equation for level is 20log(0.5). See Decibel#Field_quantities. -—Kvng 18:27, 12 November 2012 (UTC)
thread_title:  "A signal that reaches 50% of the maximum level would peak at -6 dBFS" - huh? 

message: From User:MaxEnt and User:ChamberGuy2:
−3dBFS (power) or −6dBFS (amplitude), which is 6dB below full scale.
I'm not sure that this makes any sense, can you provide a reference for "dBFS (power)"? — Omegatron (talk) 22:49, 7 February 2023 (UTC)
