Microphone selection and placement are critical factors in capturing high-quality audio, each microphone type possessing distinct characteristics that make it suitable for specific applications. Comparing and contrasting the most common types - dynamic, condenser, and ribbon microphones - and considering their ideal placement for various instruments and vocals reveals their strengths and how best to leverage them for optimal sonic results.
Dynamic microphones are known for their robustness, ability to handle high sound pressure levels (SPLs), and relatively simple construction. They function using a moving coil that generates an electrical signal when sound waves cause it to vibrate. Dynamic microphones are less sensitive than condenser mics and often preferred for loud sound sources because they can handle high SPLs without distortion. A classic example is the Shure SM57, often used on snare drums. Due to its ability to handle loud transients and its rugged construction, it’s a standard choice for snare drums. The SM57 is often placed slightly off-center and angled toward the drum to capture both the attack and the body of the sound. Additionally, the dynamic microphone is used on guitar amplifiers. Its ability to handle high SPLs and its less pronounced high frequencies mean that it doesn't pick up the high frequency fizz that often comes from guitar amps. It should be positioned close to the speaker, often just slightly off-center, ....
