A friend plays the pipe organ, I often attend his practice sessions. No reproduction even come close to the power of such an instrument, however-the organ produces enormous amounts of noise. There is the air rushing through the pipes, the sounds of the mechanical opening and closing of swell doors,not to mention the opening and closing of valves, the operation of compressors.....
An orchestra on stage is also the venue of extraneous noises. At a concert we ignore these noises, yet they can make up an important part of the experience we remember. Until recent years I did not realize how many of the noises were recorded and reproducible on modern equipment. Sometimes they add a great deal to the sense of realism- sometimes not. Those of us fortunate enough to not have to worry about our neighbors hearing our systems have a real advantage in this area.
