If I can point something out:The musicians performed for an audience of about one hundred people in a fairly large room with a sprung floor, built in 1807 by the famous builder, Samual McIntire. The acoustics are excellent. The music and performance were sublime. As live acoustic music is my reference, I paid particular attention to a few aspects of the presentation.
The first thing that struck me was the sheer energy coming off of the instruments and how resonant the cello was. The floor vibrated with that energy and it was strongly felt as we sat just 15-20 feet from the musicians. The second thing I noticed was that the violin was not very extended, not shrill, or thin, but instead, it had a very rich, colorful tone. The third thing I noticed, and this might be most controversial, was the lack of separation of the instruments.
Microphone placement has an enormous effect on how the instruments 'separate'!
You really can't assess how live sound compares to reproduced until you limit the variables! One huge variable is the room. The thing to do was to record that ensemble in the room and then play it back on your system. Then you'd know how the room is affecting the sound of the live performance.
Commercial recordings are the way they are because engineers try to give the the front row center ideal placement. Unless you've heard the same ensemble in the space in which the recording is made, you simply cannot make assessments. This is why I encourage everyone to invest in a set of decent mics and a decent recorder, so they can have a better idea of what they are hearing.
Good mics and a good recorder isn't that expensive compared to the kind of things people are talking about on these threads. The hard part is often just getting permission to record the event.
A low noise floor, free of intermodulations, harmonic and inharmonic noise, creates a 'black background'. Its not enough IOW to simply say 'low noise floor' because if that noise floor contains the stuff I just mentioned, your ears can't hear signals below that. So there's less resolution.In my opinion, language should clarify the writer’s intent, not confuse the reader. If you mean low noise floor when you write “black background”, why not simply write “low noise floor”?
If you mean something other than low noise floor, please explain what you mean.
