And guess what?… 

 

Each of these sounds, subtle or pronounced, has its own unique characteristics. 

 

Capturing them in their purest form is no small feat, which is where understanding the different types of microphones becomes invaluable.

 

#1. Capturing Vocal Nuances

 

 

When it comes to capturing vocal nuances, there are a few things you should certainly consider, such as the vocals of a specific artist.

 

Every single artist you work with has a distinct:

 

• Vocal texture
• Pitch range
• Projection

 

While one microphone might excel at picking up the deep baritones of a male rapper, it might not do justice to the higher pitches of a female vocalist. 

 

For instance, condenser microphones, with their sensitivity and frequency response, are often preferred for capturing detailed vocals in controlled studio environments.

 

#2. Instruments Have Their Own Voice

 

 

Just like vocals, instruments have their own unique voice too, so to speak.

 

The resonating sound of a grand piano, the strum of an acoustic guitar, or the bass-heavy thump of a kick drum 一 each instrument needs a specific microphone type. 

 

For example, a dynamic microphone, known for its durability and ability to handle loud sound sources, is often the go-to for miking guitar amps and drums.

 

They capture the raw power of these instruments without any distortion.

 

#3. Room Acoustics Play a Role

 

 

The environment where you record also influences your microphone choice. 

 

While some microphones are designed to pick up sound from all directions (omnidirectional), others focus on capturing sound from a specific direction (cardioid or shotgun mics). 

 

If you’re recording in a space with a lot of ambient noise, you’ll need a mic that can hone in on your sound source and reduce the background distractions.

 

#4. Versatility vs. Specialization

 

 

While some producers prefer to have a versatile microphone that’s a jack-of-all-trades, others invest in specialized mics tailored for specific tasks. 

 

For example, ribbon microphones, known for their warm sound profile, are excellent for capturing the natural tones of vintage instruments or adding a retro flavor to vocals.

 

In essence, it’s not just about recording sound, but capturing: 

 

• Emotion

A small diaphragm condenser mic is known for its precise, detailed sound.

 

In particular, small diaphragm condenser microphones excel in capturing the intricacies of acoustic instruments. 

 

Small diaphragm condenser mics are ideal for ensuring every detail is present and accounted for, like the:

 

• Delicate plucking of a classical guitar
• Shimmering resonance of a cymbal
• Intricate timbres of a violin

 

Their design is geared towards a tighter polar pattern, allowing for focused sound capture. 

 

This makes small diaphragm condenser microphones perfect for situations where ambient noise rejection is essential (such as in live sound environments) or when capturing instruments in ensemble settings.

 

Due to their size and design, small diaphragm mics are often chosen for stereo recording techniques, such as X-Y or ORTF configurations. 

 

For example, the renowned Shure SM81 or the Sennheiser MKH 40 are often used in pairs to create stereo recordings that give a lifelike representation of acoustic spaces or ensembles.

 

NOTE: While their precision is commendable, a small diaphragm condenser mic might not always be the first choice for vocals. 

 

The inherent character of large diaphragm microphones often suits the human voice better.

 

However, in certain scenarios, especially when a natural and uncolored representation is sought, these ‘pencil mics’ (small diaphragm condensers) can be the perfect choice.

 

• Recording Vocals & Acoustic Instruments

 

 

Condenser microphones, both large and small diaphragm, stand out as the gold standard for recording vocals and acoustic instruments. 

 

Their sensitivity and wide frequency response ensure that the full tonal range of a performance is captured.

 

For vocals, the clarity and detail offered by a condenser microphone, like the revered Neumann U87, can make sure a singer’s voice sounds phenomenal and shines in a mix. 

 

From the airy highs to the resonant lows, every nuance is faithfully reproduced.

 

When recording acoustic instruments, capturing the instrument’s natural resonance and overtones is crucial.

NOTE: While a dynamic mic may lack the detailed highs of condenser mics, this can often be beneficial, especially when trying to avoid harshness or excessive ambient noise.

 

Another advantage of dynamic microphones is their lack of need for an external power source; unlike condenser microphones. 

 

This plug-and-play nature, combined with their robust build, makes condenser microphones a favorite for on-the-go recording and live sound.

 

• Perfect for Capturing Loud Sound Sources (Like Guitar Amps)

 

 

Guitar amplifiers, especially when driven to high volumes, emit a significant SPL. 

 

Dynamic microphones (like the Shure SM57) have become the industry standard for capturing the roar of these particular amps.

 

The reason lies not just in their SPL handling but also in their frequency response. 

 

The roll-off in the high frequencies can prevent overly bright or harsh tones 一 preserving the warmth and richness of a guitar sound.

 

The positioning of the dynamic mic in relation to the speaker cone can drastically alter their tonal quality.

 

These specific positions of a dynamic microphone include:

 

• Center
• Edge
• Off-axis

 

This flexibility allows sound engineers and producers to tailor the sound to their preferences using just one dynamic mic.

 

Similarly, drum kits, known for their explosive transients and volume, which technically makes them ‘loud instruments,’ are often miked with dynamics (a dynamic microphone).

 

A top-pick dynamic mic, like the Audix D6 for kick drums or the Sennheiser MD 421 for toms, can ensure that the power of the kit is captured without distortion.

 

So, if you’re a producer thriving for the most pristine recordings and epic mixes, dynamic microphones can be your best friend.

 

Ribbon Microphones: The Delicate Touch

Always ensure compatibility before engaging phantom power.

 

Cardioid Mics: Directional Mastery

 

The cardioid microphone, named after its heart-shaped pickup pattern, specializes in honing in on sound from a specific direction while rejecting sounds from the sides and rear.

 

• The Cardioid Pattern & its Benefits

 

 

The cardioid pattern is the most common directional pattern found in microphones. 

 

Its ability to focus on sound coming from in front of it while rejecting ambient noise from the sides and back makes it highly versatile and suitable for a variety of recording situations.

 

This pattern is particularly useful in live settings; where onstage monitors or unwanted noise from the audience might interfere with the desired sound. 

 

It ensures that the microphone picks up primarily the intended source.

 

Another advantage is the reduced feedback. 

 

Since feedback often originates from speakers positioned to the sides or behind the microphone, the cardioid’s rejection capabilities are invaluable in preventing it.

 

The effectiveness of the cardioid pattern, however, can vary based on the microphone’s design and quality (especially the cardioid dynamic mic).

 

Some may offer a tighter or broader cardioid pattern 一 while others can veer slightly towards super-cardioid or hyper-cardioid patterns.

 

• The Difference Between Cardioid Mics & Other Types of Microphones

 

 

While the cardioid pattern is a polar pattern, not a microphone type, it is most commonly associated with both dynamic and condenser microphones. 

 

However, what differentiates cardioid microphones from other types of microphones, like omnidirectional microphones or figure-8 microphones, is their directionality.

 

Omnidirectional mics capture sound equally from all directions 一 making them more prone to room noise and less suited for isolated sound sources. 

 

Figure-8 mics capture sound from both the front and back but reject sounds from the sides.

 

Cardioid mics, given their focus, are the go-to for situations requiring sound isolation. 

 

From podcasting to studio recordings where ambient noise rejection is crucial, their directional mastery shines.

 

It’s also worth noting that within the cardioid family, variations like supercardioid and hypercardioid offer even tighter front-focused patterns but with slight rear sensitivity.

 

Knowing the intricacies of different types of microphones is the first step to creating pristine tracks and choosing the right mic for your specific needs.
