Sounds better at home

It is a matter of acoustics and loudspeakers placement, why most of them lose the sound quality

Actually, singleendedsingle, it is more a matter of "sound engineers" ruining the natural acoustics with their mikes and mixing boards and loudspeaker placement. This even happens in very good concert halls, where pops concerts are almost always unnecessarily and very badly miked. It's never an improvement (assuming a good room, of course), and its downright criminal sometimes.

Learsfool, could you give an example of how you would mic a piano trio (piano, bass, drums)? What would be your preferred mics, how many would you use and approximately where would you try to place them? You've stated that sound engineers don't have a clue, so here's your opportunity to give them a clue.

Onhwy61, assuming you are serious, there is obviously no single answer to this question. It would depend very heavily on the location, and the acoustics of the space, and the type of music being performed. No good recording engineer ever sets up anything the same way every time - there are far too many variables. As for preferred equipment, again it depends on the type of sound wanted on the recording, or at the live event. I of course did not mean to imply that all recording/sound guys were bad - there are many great ones out there, all with different priorities and preferences. That said, you would be very surprised at how many that do this type of thing for live events have no real musical ears or priorities - they just set it up to be as loud as possible, assuming that this is what the audience wants. It is very rare and refreshing nowadays to find a good jazz venue, for instance, that is not over-miked, even when the musicians themselves complain, as we often do.

"No good recording engineer ever sets up anything the same way every time - there are far too many variables."

Someone should mention this to Rudy Van Gelder.
