A microphone’s position in relation to the sound source also can affect frequency response. When a directional condenser microphone is placed close to a sound source, low frequencies are boosted. This is called the proximity effect. Because omnidirectional microphones pick up sound from all directions, they do not exhibit this effect. Offaxis coloration is another characteristic of directional microphones. Sound from outside the microphone’s optimum pattern can interfere with the desired sound source, making the overall image ill defined or muddy.

As you’re finding the right placement for the mic, don’t forget to factor in the sound of the room. Listen for any ambient noise, strange hums, bizarre reflections, and reverberation. You may decide to put the microphones closer to the instrument to diminish the environmental interference. This is called tight, or close, miking. Be sure to bring your ear down to where the microphone is placed to get a perspective of what the microphone hears. To get a better idea of what the mic is hearing, plug one ear and put the other close to the sound source. Just be careful that the volume of the sound source isn’t loud enough to damage your hearing when you do this.
