Instrument directionality shapes the captured spectrum depending on mic placement

Evidence

The positioning of the microphones is critical, since the frequency-dependent directional patterns of many instruments have a major effect on the magnitude spectrum of the sound radiated in different directions (Pätynen and Lokki, 2010). Such recording is often complemented with distant microphones, which are used to record the sound from the sources through the response of the room. Such microphones are often called ambience or ambient microphones. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1835
