The Sound of Live Music
Doing a recording of our local symphony orchestra - I just wanted to relate my impressions of the sound of the live music last night before I master a disc of it and listen to the playback. I tried to close my eyes and determine a little more exactly – describably – what I was hearing. I have found that only by putting it into words can we relate these subjective experiences.
If you keep your eyes open, it is very difficult to isolate the sound of the experience. It messes with your brain when you see them playing. So closed it is. I find that there is not so much all of this hi fi “pinpointed” localization or holographic imaging that is described in the subjective reviews of hi fi equipment, especially speakers. The main impression is spaciousness, or open-ness of the sound. At a certain distance – and not very far at all – the instruments are far enough and submerged enough into the reverberant field that the direct sound is such a small part of it that only the highest of frequencies make their way through the rich reverberant field to do whatever localization is left. The splash of the cymbals – kind of over on the left side; the bowing of the deep strings of the double bass, on the right; the kettle drums – back there somewhere near the center. Each instrument just sounds bigger than it really is and its sound blends with the rest in a way that enriches the total experience. It is just the opposite of a group of separate sounds playing in an anechoic chamber. The full sound power output of each instrument reaches your ears and enables you to hear all of its overtones and radiation into the room. The room itself is unrestricted; you do not hear the size of the room specifically, nor do you detect where the walls and other physical reflections are – it is just “big.” I wish I could have measured the reverb time in the church. It was a fairly large church with good acoustics. Not a long reverb that I could detect. I think that in spaces with long reverb times in the right seats you will hear a “stereophonic” reverberance that differs on the two sides from the different instruments on the right and left, and if the early reflected trails off smoothly it will not be noticed as “echo” but rather as additional spaciousness.
I will now make a CD of the music and play it in the listening room and close my eyes once again. I will try and hear if there are any hotspots in the sound field in front of me. There shouldn’t be; the music should just be huge and spacious and not limited to a 21 ft wide room but rather spread widely in an arc about 130 to 150 degrees in front and around me. The early reflected plus the surround speakers should help get me there – it was recorded in MS with a +2 setting for the side mike.
Has anyone else performed this experiment with “the absolute sound” – especially you recording engineers? What do you hear with live music?
