Remember that epic mountain bike ride you filmed? The scenery was breathtaking, but the wind drowned out your excited shouts. Picking the right microphone for your action camera can make all the difference between capturing amazing memories and capturing muffled sounds. This guide will help you choose the best what type microphone for an action camera, ensuring crisp, clear audio enhances your videos.
Understanding Action Camera Audio Challenges
Action cameras, due to their small size and often outdoor use, face unique audio challenges. Wind noise, distance from the subject, and the camera’s own internal microphone limitations contribute to poor sound quality. This section will explore these challenges and how different microphone types address them.
Wind Noise Reduction
- Windshields (Deadcats): Fuzzy covers that slip over microphones reducing wind noise. These are inexpensive and effective for mild winds. They work by disrupting the airflow and minimizing the impact of wind pressure on the microphone diaphragm. However, they can slightly muffle audio.
- Supercardioid and Hypercardioid Microphones: These microphones have a highly directional pickup pattern. This means they pick up sound primarily from the front and reject sound from the sides and rear, reducing the impact of wind and background noise. They often perform better than omnidirectional mics in windy conditions.
Distance and Audio Pickup
- Omnidirectional Microphones: These pick up sound equally from all directions. This makes them suitable for recording ambient sounds, but they are not ideal for focusing on a specific sound source at a distance. Because they pick up all sounds, they can sound less clear.
- Directional Microphones (Cardioid, Supercardioid): More suitable for capturing audio from a specific direction, crucial when the subject is a distance from the camera. The directional properties allow for a cleaner recording by focusing on the primary sound source.
Internal Microphone Limitations
Many action cameras have built-in microphones, but these are often low-quality and susceptible to interference. External microphones generally offer a significant improvement in sound quality due to the use of higher-quality components and better shielding against noise. Upgrading improves the quality considerably.
Types of Microphones for Action Cameras
This section will outline the various microphone types and their suitability for action cameras, helping you understand which one best suits your needs and recording style.
External Microphones
- Shotgun Microphones: These highly directional microphones are excellent for isolating a sound source, especially when combined with a deadcat for wind noise reduction. Their elongated design allows for specific audio capture, reducing background noise. However, they may require careful positioning.
- Lavalier Microphones (Lapel Mics): These clip-on microphones are great for capturing clear audio from a subject close to the camera. They’re particularly useful for vlogging or interviews during action-based activities. They are often less susceptible to wind noise than other microphone types. However, they require the subject to wear the microphone.
- Wireless Microphones: These offer freedom from cables and are useful for scenarios where the action camera is moving dynamically. They often improve audio quality as the microphone is positioned nearer the subject, and also improve the audio capture. However, they often require separate receivers and can be expensive.
Choosing the Right Microphone Based on Activity
The best microphone for your action camera depends heavily on the type of activity you’re filming. Different activities present different audio challenges.
Omnidirectional Microphones: Considerations
While convenient, omnidirectional mics pick up sounds from every direction, resulting in a less focused audio recording. This is less ideal for action scenes. This type of microphone is not suitable for many action camera scenarios.
Connecting Your Microphone to Your Action Camera
Connecting your external microphone to your action camera is typically straightforward but varies slightly depending on the camera model and microphone type. This section will cover the common connection methods and troubleshooting tips.
3.5mm Jack Connection
Most action cameras use a 3.5mm audio input jack. This is a standard connection for many external microphones. Simply plug the microphone’s 3.5mm connector into the camera’s jack. Ensure a secure connection to minimize audio interference. It is inexpensive and easy to implement.
USB-C or Other Proprietary Connections
Some newer action cameras may use USB-C or other proprietary connectors for audio input. Check your camera’s specifications for compatibility before purchasing a microphone. You may need an adapter.
Troubleshooting Audio Issues
- Check Connections: Ensure the microphone is securely plugged into the camera’s audio input.
- Microphone Power: Some microphones require phantom power, which must be enabled in your camera settings. If not, it is unlikely to record sound.
- Test Recording: Record a short test clip to check audio levels and quality.
Microphone Accessories and Enhancements
Various accessories can further improve the quality and versatility of your action camera’s audio.
Windshields (Deadcats) and Other Wind Protection
Essential for outdoor filming, these fluffy covers significantly reduce wind noise. Different sizes and densities cater to various wind conditions. This is usually inexpensive and highly recommended.
Shock Mounts and Suspension Systems
These reduce handling noise and vibrations that can be picked up by the microphone. They are often used in conjunction with more sensitive microphones to minimize extraneous noise. They can isolate the microphone from camera movements. This can greatly improve audio quality.
Microphone Cables and Extensions
High-quality cables minimize signal loss and interference, providing cleaner audio. Extensions allow for more flexibility in microphone placement. Longer cables provide flexibility in microphone placement. This is often overlooked but essential to audio capture.
Debunking Common Myths about Action Camera Microphones
Myth 1: Internal Microphones are Sufficient for High-Quality Video.
While convenient, internal mics are typically low quality and capture poor audio. External mics are essential for clear, professional-sounding videos.
Myth 2: Expensive Microphones are Always Best.
While higher-end microphones offer superior features, a budget-friendly microphone can significantly improve audio over a camera’s internal microphone. Your needs should drive the choice.
Myth 3: All Directional Microphones are Created Equal.
The degree of directionality (cardioid, supercardioid, etc.) impacts the microphone’s sensitivity to sound from different angles. Choose the right one for your needs.
FAQ
What is the difference between a cardioid and an omnidirectional microphone?
A cardioid microphone picks up sound primarily from the front, while an omnidirectional microphone picks up sound equally from all directions. Cardioid mics are better for reducing background noise in many action camera applications.
Do I need a special adapter for my microphone?
It depends on your camera and microphone. Most action cameras use 3.5mm jacks, but some may require adapters for different microphone types or connectors. Check the compatibility of your equipment.
How do I reduce wind noise during outdoor recordings?
Use a windshield (deadcat) over your microphone. Alternatively, consider a microphone with a highly directional pickup pattern that rejects sounds from the sides and rear, effectively minimizing the impact of wind noise. Also consider filming in a location with less wind.
Can I use my smartphone microphone with my action camera?
Usually not directly. Smartphones use different audio connectors than action cameras typically do. You would likely require an adapter, and sound quality might still be an issue.
What type of microphone is best for vlogging with an action camera?
A lavalier (lapel) microphone is ideal for vlogging as it’s small, unobtrusive, and can be easily clipped to your clothing, providing clear and close-range audio capture.
Are wireless microphones worth it?
They offer freedom of movement but are generally more expensive and require a receiver. They’re worth considering if capturing audio from a distance or in scenarios requiring mobility is crucial. Consider wireless microphones for improved sound quality and freedom of movement.
How do I adjust microphone levels?
Check your action camera’s settings menu for audio input level adjustments. This will control how sensitive the microphone is and prevent clipping (distortion from an audio signal that is too loud).
