Hi,
I'm recording speech for radio broadcasts. I'm pretty satisfied with my combination of the Sennheiser MD 421 and the Marantz PMD 661 MkII - it's very low-noise. But still, when I record people with quiet voices and normalize them afterwards, sometimes noise/hiss is clearly noticeable. Not a big issue, but still annoying from a perfectionist's point of view. Does this also depend on the room I'm recording in? I'm talking about quiet rooms without computer fans, air conditioning etc., but not studio environments, e.g. offices which have some reverb. Is there such a thing as "room-inherent noise" which gets recorded (besides the obvious reverb)?
