noise floor

Hi everyone,

Hello,



Is there any reason why my noise floor would differ while speaking vs when just recording the tone of the room?



My recorded noise floor seems to be lower when speaking; -85 and higher when I just sample the "tone" of the room, it's at -60. Is that because my voice is blocking most of the noise floor?

i have a few cad e100s's on the way and if what i have seen is true it has a very low noise floor, 3 point something dba, and i wanna keep the "low noise" signal going, so does anybody have any opinions on which cable has the lowest noise floor?

i'll be running them very short, around 15 foot or less

any help thanks

The amount of self-noise generated by a piece of electrical equipment when it is at rest (no signal passing through.) All such devices generate noise to some extent or another, and engineers are constantly striving to lower this artifact. Measured in decibels.

ok i know this is very basic question and i feel like an idiot for asking so dont chastise me any further.

i think i understand what noise floor is but could someone further explain this to me (yes i have searched it but to no avail) and how i can measure it in my studio.

is it basically just recording silence with all equipment on?

hello.

i was recording my synthesizer SY 85 into Apogee trak2 through coaxial digital cable using Sony Sound forge apps.

even though i didn't play SY 85, the noise floor level is changing

why did it happen?

the noise level was -69 dbfs, but suddenly it was changed to -79dbfs. then again it was -79dbfs

I'm not sure this is a mastering question, but I'd like some feedback from mastering experts if possible. I'm recording solo acoustic guitar (think Alex de Grassi, or Leo Kottke, or...) in my home studio. I've been doing a lot of work on reducing noise and have made a lot of progress, but I'm curious how much further I need to go.

Why is it?

That when I first start the recording process, in Acid. . I get this 6db "noise"? It happens everytime.



I found a "workaround" by copying the name of the track. Starting the recording. . Canceling it and then restarting it, under the same name. Fixes it every time. :)

And, actually, this isn't much of a problem.
