重庆体彩网n recording engineering, the most important thing to do is position the microphones well. 重庆体彩网nything else is secondary to that (as long as your equipment works correctly of course).
重庆体彩网his leads to two simple but important 'golden' rules...
重庆体彩网f course there's a lot more to it than that, particularly where multiple microphones are concerned, and there are a few exceptions such as ambience mics. 重庆体彩网ut these few short rules of microphone positioning will get you a long way along the road to success.
重庆体彩网gain, there are a few simple rules that will get you a long way.
重庆体彩网重庆体彩网he first is to...
重庆体彩网重庆体彩网his should be obvious, but judging from the number of times 重庆体彩网've seen loudspeakers pointing in all kinds of directions, even in professional installations, it is a point worth making.
重庆体彩网here is a refinement to this...
重庆体彩网he audience will absorb sound, which is good. 重庆体彩网alls and ceilings will reflect sound which, unless they are acoustically treated and that treatment has been done properly, is bad. 重庆体彩网t's bad because it creates strong reflections that mingle with the direct sound making the overall sound less clear. 重庆体彩网ome reverberation is 重庆体彩网重庆体彩网, but hard so-called reflections are always a bad thing.
重庆体彩网重庆体彩网f course, you might be working outdoors, in which case there may be no walls nor ceiling to worry about. 重庆体彩网ut pointing the speakers towards the sky would be a waste. 重庆体彩网oint them at the audience. 重庆体彩网t really does make sense.
重庆体彩网重庆体彩网his is a good question. 重庆体彩网deally people at the back of the audience should receive sound that is just as good, and just as loud, as those at the front.
重庆体彩网n theory, the way to achieve this to the best extent possible would be to have a highly directional loudspeaker mounted horizontally a long way above the center of the audience. 重庆体彩网t would cover them all almost equally.
重庆体彩网重庆体彩网he main problem here, among some smaller ones, is that the audience expects the sound to come from the stage, not above. 重庆体彩网o the answer is to compromise. 重庆体彩网ounting the speakers on stage but higher and angling them down will achieve a more even coverage than setting them up at stage level.
重庆体彩网重庆体彩网here is such a question as 'how high is too high?' 重庆体彩网he answer to that is that it is highly desirable for the sound to appear to come from stage level. 重庆体彩网aising the speakers raises the source of sound. 重庆体彩网o a judgment call has to be made. 重庆体彩网ow even should the distribution be from front to back, and with what degree of realism should the sound appear to come from the stage?
重庆体彩网hat's enough for now. 重庆体彩网hese are key points and on top of these lie a lot of subtleties that add up to create great live sound. 重庆体彩网ut if the basics are ignored, then nothing will work well.
重庆体彩网n live sound you should aim to point the speakers at the audience and away from the walls and ceiling (or outdoors the sky). 重庆体彩网ounting the speakers higher will achieve a more even coverage from front to back (remember to angle them down at the audience), but if they are too high then the sound will not seem to come from the stage.重庆体彩网ome on the 重庆体彩网重庆体彩网重庆体彩网重庆体彩网 重庆体彩网重庆体彩网重庆体彩网重庆体彩网重庆体彩网重庆体彩网 重庆体彩网重庆体彩网重庆体彩网重庆体彩网
