Microphone Types for Music Recording: an In-Depth Look

The recording world is as diverse as the sounds it captures, with various devices and techniques employed to attain the desired auditory output. At the heart of this intricate process are microphones, often underappreciated but indispensable tools. In this article, we explore the different types of microphones used in music recording, their respective strengths and weaknesses, and important concepts that underpin their operation.

The three primary types of microphones commonly employed in music recording are dynamic microphones, condenser microphones, and ribbon microphones.

Microphone Types

Dynamic Microphones

Dynamic microphones, or moving-coil microphones, use electromagnetic induction to transform sound into an electrical signal. A thin diaphragm, connected to a coil of wire, vibrates in response to sound pressure, moving within a magnetic field and generating an electrical signal.

Advantages: Dynamic microphones are known for their durability and high tolerance to loud sounds. They are typically used in live sound scenarios due to their ruggedness and ability to withstand physical mistreatment. This makes them an ideal choice for instruments producing high sound pressure levels, such as snare drums or guitar amplifiers.

Disadvantages: While their robustness is commendable, dynamic microphones may not capture high frequencies as accurately as other types, and can lack in detail and transient response. Additionally, they may exhibit proximity effect – a boost in bass frequencies when the microphone is close to the sound source.

One of the most iconic dynamic microphones is the Shure SM58. Recognizable for its robust construction and exceptional sound quality, it has been a staple for vocals in both live and studio environments for many decades. The Shure SM57 is another popular dynamic microphone, often used for instruments due to its ability to handle high sound pressure levels, clear mid-range and presence boost.

Condenser Microphones

Condenser microphones operate based on a capacitor’s capacity to store electrical charge. They employ a lightweight diaphragm, or ‘backplate,’ adjacent to a solid metal plate. When sound strikes the diaphragm, the capacitance changes, translating this into an electrical signal.

Advantages: Condenser microphones are exceptionally responsive and can capture a wide range of frequencies with great accuracy. This makes them a preferred choice for studio recordings, particularly for vocals and acoustic instruments, where detailed and transparent sound is essential.

Disadvantages: Condenser microphones require an external power source, either through battery or phantom power, to polarize the capacitor. They are also more delicate compared to dynamic microphones and may not handle extremely high sound pressure levels as efficiently.

The Neumann U87 is perhaps one of the most renowned studio microphones, with a rich history of use in professional recording settings. It is loved for its detailed and accurate sound reproduction across various sources. The AKG C414 is another well-regarded condenser microphone, offering multiple polar patterns and a broad frequency response, making it very versatile in a studio environment.

Ribbon Microphones

Ribbon microphones use a thin strip of metal, typically aluminum, suspended in a magnetic field. Sound vibrations cause this metal ribbon to move within the magnetic field, inducing a current that is transformed into an electrical signal.

Advantages: Ribbon microphones are acclaimed for their warm, natural sound and ability to capture subtle details. Their bidirectional (figure-eight) polar pattern picks up sound from the front and rear, making them ideal for certain stereo recording techniques like Blumlein.

Disadvantages: They are the most fragile of the three types, often requiring special care during use and storage. Ribbon microphones also exhibit a pronounced proximity effect, and their high-end frequency response can be less accurate than condenser microphones.

The Royer R-121 is a highly respected modern ribbon microphone. It’s known for its warm, realistic sound and excellent side rejection due to its figure-eight polar pattern. The AEA R44C, a recreation of the classic RCA 44, is another celebrated ribbon microphone, noted for its smooth, vintage sound that has been a favorite in broadcasting and music recording since the 1930s.

Important Concepts

When selecting a microphone, consider its polar pattern, or the sensitivity to sound from different directions. Common patterns include cardioid (sensitive to front, rejects rear), omnidirectional (equally sensitive all around), and bidirectional (sensitive to front and rear, rejects sides).

Another consideration is frequency response, which refers to how a microphone reacts to different frequencies. A ‘flat’ response captures all frequencies equally, whereas some microphones enhance certain frequencies to ‘color’ the sound.

Lastly, sensitivity and signal-to-noise ratio (SNR) are crucial. High sensitivity microphones generate stronger output and require less preamp gain, thus having lower noise. A high SNR ensures that the desired signal (the music) is much louder than the undesired signal (background noise).

Remember, the choice of microphone will often depend on the specific requirements of the recording session and the characteristics of the sound source. An understanding of the strengths and weaknesses of different microphone types can aid in making the most appropriate selection.


In conclusion, each microphone type offers unique features that make it suitable for different recording environments and applications. As an audio engineer, understanding the specific characteristics of dynamic, condenser, and ribbon microphones, and the critical concepts of polar patterns, frequency response, and sensitivity, is key to making informed decisions in the recording process. The right microphone not only captures the music but also adds depth and character to the sound, helping to create a memorable recording. Remember, the best microphone is the one that best serves the sonic needs of the recording at hand.
