hello everyone, this is my first post...
I'm a DJ and i've tryed to record a live dance mix performance with the public reactions. The ideia is to have a hi-quality sound of the music played, but mixed with the public reactions (when the public sings parts of the songs they know, applause, etc.)
the event i'm talking about did take place in a very large circus tent, with a complete PA system.
to do this, i've placed a mono microphone in the middle of the tent, and mixed live the microphone sound with the main mixer sound in a second mixer, and the output was feeded to minidisc.
this way:
CD's->Main Mixer->PA->speakers->microphone on middle of tent
...................|______________________|
.............................................|
......................................second mixer
.............................................|
.............................................v
.......................................MINIDISC
i've made this setup to try to have a good quality sound from the main mixer, which the public was added in real-time.
well, it worked, but with a very poor "hollow" sound. the beat was not clear. i've attached a small sample of teh actual final recording quality. it's from a major hit some years ago, and you can compare the beat with the original one... this sounds terrible.
i believe that was wappened is that the public sound was too loud, and catched the loadspeakers beat, which is equal to the main mixer sound, BUT COME LATER. how much later? if the microphone was 10 meters from the loudspeakers, as the sound speed is constant at 333 meters/second, then it had a delay of 30ms, which causes this efect.
Also consider that the way the tent was, it caused another artiact on the beat: as the tent was very large, and the loudspeakers only on one side, it could be heard double beat: the real beat, and the sound reflection of the opposite wall, when it returned.
(i could also get a stereo mic, and record only the sound from the mic, but then quality was even poorer!)
so my question is: how can i record a perfect quality live recording?
PS: i'm thinking on another way (not tested yest): record both the main sound, and public sound on separate Minidiscs. then convert it the the computer, and use cooledit's multitrack feature to mixdown both takes, BUT manually resync that difference of 30ms, so that the beats were aligned.
PS2: another ideia that i'm having right now is to record the public is the low frequencies cut, to remove the bass there.
sorry for the long post,
