Just the reverse, Capacity! We *all* have that problem. It is an unfortunate fact of life that microphones are made to pick up sound, and that's what they do. You can't train them to ignore unwanted noise, and mostly, you can't remove that unwanted noise after the fact without removing part of the music, if at all. We of the acoustic persuasion suffer the most, because our source is very delicate. You can cover up a lot of noise with a death metal band, not so much with a mandolin. I am lucky enough to have a room that shuts out most of the outside world, but not the house. When the red light is on, my wife is exiled to the 3rd floor bedroom to read quietly with the cats, who are also banished. No one can walk on the second floor, or use the bathroom. Television? Not without headphones. I have to unplug the sump pump, turn off the heat, kill the pool timer (it ticks), lose the watch (the Neumanns can hear it ticking 10' away). I know the train schedules by heart. The simple horrifying fact is that recording acoustic music requires absolute elimination of ambient noise, and good mics and preamps will reveal noises you didn't even know were there. Furthermore, the more noise you have, the more it costs to make it go away. Do a search on "vocal booth", which is sort of an isolation box for humans. It's a royal pain in the ass, but it might be a partial solution for you. We all feel your pain, and every one of us that records acoustic music has been where you are. We're there for you, but there really is no magic wand. Mics record whatever sound is there, and you can't really change that. Good luck.-Richie
