When it comes to selecting the right microphone for your needs, understanding pickup patterns is essential. Two of the most commonly used directional microphone types are hypercardioid and cardioid microphones. While they may seem similar, they have key differences that make them suitable for different recording and live sound applications. In this article, I'll break down the differences, explore their strengths and weaknesses, and highlight some popular models of each type.
What Is a Cardioid Microphone?
A cardioid microphone has a heart-shaped pickup pattern, meaning it primarily captures sound from the front while rejecting noise from the sides and rear. This makes it an excellent choice for isolating a sound source and reducing background noise. These are the tried and true microphones that the live music industry have been relying on for years!
Pros of Cardioid Microphones:
- Excellent for live performances and studio recording
- Reduces unwanted background noise and limits room reverb being picked up in microphone
- Minimal risk of feedback
- Ideal for vocal and instrument recording
Cons of Cardioid Microphones:
- Still picks up some side noise
- Not as directional as hypercardioid mics
Popular Cardioid Microphones:
Shure SM58 – One of the most iconic dynamic vocal microphones, used in live performances worldwide. Also used to record many albums such as one of my favorites The Killers Hot Fuss!
Audio-Technica AT2020 – A popular budget-friendly condenser microphone for home studios.
Neumann TLM 103 – A high-end studio condenser microphone known for its clarity and warmth.
What Is a Hypercardioid Microphone?
A hypercardioid microphone has a more directional pickup pattern than a cardioid mic. While it still captures sound from the front, it has a narrower focus, rejecting more noise from the sides but picking up slightly more sound from the rear.
Pros of Hypercardioid Microphones:
- Superior side noise rejection
- Great for isolating a sound source in noisy environments. I have used this for isolating drum bleed live!
- Ideal for broadcast, theater, and film applications
Cons of Hypercardioid Microphones:
- Picks up some sound from the rear. This can cause feedback if a monitor is directly in front of the mic
- Requires precise positioning to avoid unwanted noise as well as pickup the vocals correctly
- More prone to feedback than cardioid mics
Popular Hypercardioid Microphones:
Sennheiser MKH 50 – A high-quality shotgun-style hypercardioid mic used in film and TV production.
Electro-Voice RE20 – A dynamic mic favored for radio broadcasting and podcasting.
AKG C414 XLII – A versatile condenser microphone with multiple polar patterns, including hypercardioid.
Which Microphone Should You Choose?
Choosing between a cardioid and hypercardioid microphone depends on your specific needs:
If you need a microphone for live vocals, podcasting, or general studio use, a cardioid microphone is likely the better choice.
If you’re recording in a noisy environment or need to isolate a specific sound source, a hypercardioid microphone will provide better rejection of unwanted noise.
Final Thoughts
Both cardioid and hypercardioid microphones serve important roles in the world of audio recording and live sound. Understanding their differences can help you make the best choice for your setup. Whether you're recording vocals, instruments, or ambient sound, selecting the right microphone can make a significant impact on the quality of your audio.
