i have generally always recorded individual instruments (mostly flute) using my single best mic (AT 4050) to one track. works fine in duets and trio mixes, but for solo performances, it tends to put the instrument a bit too "in your face" in the center, when compared to commercial CDs. i have been experimenting with doing them in stereo with a pair of matching, but less expensive mics (akg c3000s). do the pros "spread" the sound by recording the solo flute in stereo, or are they recording in mono and doubling it with a delay and panning the original and the delay a bit off center?
