ABSTRACT
I’ve found the ORTF technique to be unsatisfactory. It works fine for listening on headphones, but on loudspeakers there’s not enough width, and it tends to be too dry. If I moved the mics back, there could be too much ambience, especially in a bad sounding room. With a spaced pair of omni microphones, you get accurate low frequency response and, I think, a more natural high frequency sound. Omnis do pick up a lot of ambience so generally need to be placed closer, but not so close that one hears too many individuals. It goes back to needing good room acoustics to start with, and having enough of a blend coming through without having to move the mics back too far.
