Basic two-microphone stereo techniques
The focus in this chapter will be on the two-microphone stereo techniques that are frequently referred to throughout the book for non-orchestral recordings such as piano, chamber music, choirs, and organs. These fundamentally useful techniques are co-incident directional microphones, spaced omnis, and spaced and angled cardioids (of which the ORTF pair is the most well-known example.)
