Understanding Your Microphone
First things first, know your mic! Different microphones have different pickup patterns. Cardioid mics, for instance, are great at rejecting sound from the sides and behind, focusing on what’s directly in front. Omnidirectional mics pick up sound equally from all directions, ideal for capturing the ambience of a room.

The 3:1 Rule
This handy rule applies to stereo miking techniques. To achieve a natural stereo image, place your mics apart, with one microphone three times the distance from the sound source compared to the other. This creates a wider, more realistic soundscape.
Mind the Room
Rooms have their own sonic personalities. Bare walls reflect a lot of sound, leading to a bright or harsh recording. Conversely, rooms with heavy furniture absorb sound, creating a duller tone. Experiment with mic placement to find the sweet spot. Avoid corners and walls, which can cause unwanted buildup of certain frequencies.
Strategic Placement for Different Scenarios
Solo Instruments: For a clear and focused sound on acoustic guitar or vocals, position your cardioid mic a few inches off-center from the soundhole or mouth. Experiment with height as well. Generally, aiming the mic slightly above the sound source provides a good balance between warmth and brightness. You can move the mic closer for a more intimate and detailed sound, or farther away for a fuller, more ambient tone.
Drums: A common technique is to use a close-up mic on each drum piece. Aim the kick drum mic at the beater head, and snare mic slightly above the rim, around 1-2 inches away. For hi-hats, position the mic directly overhead at a close distance to capture the cymbal attack. Along with close mics, use a room mic overhead to capture the overall kit sound and ambience. Experiment with the height of the room mics – higher placement captures more cymbals and ambience, while lower placement focuses on the body of the drums.
Live Performances: For bands, strategically placed cardioid mics in front of each instrument are a good starting point. Aim for the sweet spot of the instrument – the area where it projects sound the strongest. Consider using omnidirectional mics for audience ambience, but be mindful of placement to avoid picking up too much PA bleed. Microphone height here is crucial for singers. Ideally, position the mic stand so the capsule is level with the singer’s mouth when standing upright.
The Art of Listening
Ultimately, the best mic placement is the one that sounds best to your ears. Trust your judgment! Record some test runs, listen back, and adjust the microphone positions and heights as needed. There’s no one-size-fits-all approach, so experiment and have fun!
By following these tips and using your ears, you’ll be well on your way to capturing professional-sounding recordings in any room. Remember, practice makes perfect, so grab your mics and start experimenting!
