Noise Floor
I record vocals low, and I need to get more volume. So I use compression and limiting to get more volume. However when I do this I get the white noise in the background.
How can I get volume without the noise?
I would say, at least you could try Reafir from Coockos (free plugin from Reaper).
You can make a sound profile from your noise floor and substract all that from track.
Works good for me.
However, not sure about Reason (3rd party plugin) but at least you could try it with another software (Audacity ?!)
