my studio is a single large room. i must record a flute quartet performing pieces that must be played in an ensemble setting (live, all four parts at once so they can see each other as they do accelerandos and ritards, etc). since the pieces are difficult, i need to multitrack to allow for punch-in corrections. how can i acheive adequate isolation of up to four live acoustic instruments at a time in my studio? how would they do this in a real studio?
