Tip 1: Picking the Best Microphone
Microphone Types for Interviews
Shotgun Microphones
Shotgun mics pick up sound from one direction. They block out most background noise, making them great for outdoor use. The Audio-Technica AT897 works well for clear outdoor audio.
Lavalier Microphones
Lavalier mics are tiny and clip to clothes. They are hands-free and keep sound steady. The DJI Mic 2 cancels noise but keeps some natural sounds.
Studio Microphones
Studio mics are made for quiet spaces. They give clear sound, perfect for podcasts or studio talks. The Logitech Blue Sona is a top pick for pro-quality audio.
USB Microphones
USB mics are easy to use and plug into computers. They are great for online interviews. The RODE Podcaster gives clear sound with simple setup.
Dynamic Microphones
Dynamic mics are tough and flexible. They block background noise and work well for live events. The SHURE SM58 is a popular choice for interviews and shows.
Tip 2: Setting Up Microphones Correctly
The 3:1 Rule for Multiple Microphones
What It Means and Why It Helps
The 3:1 rule helps keep sound clear when using many microphones. It means the space between microphones should be three times the distance from the closest microphone to the speaker. This stops sound problems caused by microphones picking up the same noise at different times.
Steps to Use the Rule
First, measure the space from the speaker to the nearest microphone. Multiply that number by three. Place the next microphone at least that far away. For example, if the first mic is one foot away, the second mic should be three feet away. This setup works well for interviews with two people.
Stopping Comb Filtering and Sound Problems
What Causes Comb Filtering
Comb filtering happens when two microphones hear the same sound at different times. This makes the audio sound strange or hollow. It often occurs when microphones are too close or their signals mix.
Ways to Fix the Problem
To stop comb filtering, use microphones that pick up sound from one direction. Keep enough space between microphones by following the 3:1 rule. In noisy places, use a cardioid microphone to block side and back noise.
Tips for Placing Microphones
Shotgun Microphones: Aim at the Chin
Point shotgun microphones at the speaker’s chin. This helps capture clear sound and reduces background noise. Use a stand with a boom arm to hold the mic steady and at the right height.
Lavalier Microphones: Clip Near the Neck
Attach lavalier microphones to the neckline, about six inches below the mouth. This keeps the sound steady and the mic hidden. Lavalier mics are great for interviews because they stay close to the speaker, even if they move.
Using Stands for Stability
Keeping the microphone steady is very important for good sound. A shaky mic can make the audio uneven and distract listeners. Stands help keep the microphone still and in the right spot.
Desk Stands for Table Setups
Desk stands are great for interviews at tables or desks. They hold the microphone steady and at a good height for clear sound. Choose adjustable stands to easily change the mic’s position. For example, a swivel arm stand lets you point the mic at the speaker’s mouth without blocking their view.
To use a desk stand, put it on a flat surface near the speaker. Make sure the mic points at the speaker’s mouth or chin for clear sound. For two-person interviews, use one desk stand for each microphone. This setup avoids sound problems and captures both voices clearly.
Pro Tip: Add shock mounts to desk stands to stop vibrations from table movements. This improves sound and removes unwanted noise.
Floor Stands for Low Seating Arrangements
Floor stands are best for interviews on couches, chairs, or low seats. They can be adjusted to place the mic at the right height. Pick stands with strong bases to keep them from tipping over.
To set up a floor stand, place it slightly to the side of the speaker. Adjust the height so the mic lines up with the speaker’s mouth or chin. For two-person interviews, set the stands evenly to balance the sound.
Floor stands are helpful for interviews where people move around. They stay steady, keeping the sound clear and even.
Pro Tip: Use floor stands with boom arms for more flexibility. Boom arms let you change the mic’s angle without moving the stand, making it easier to record natural conversations.
Tip 3: Important Extra Equipment
Tools to Place Microphones Correctly
Boompoles: K-Tec Graphite Series and Rode Micro Boompole
Boompoles help you place microphones in the right spot. The K-Tec Graphite Series is light and strong, easy to hold for long times. The Rode Micro Boompole is small and great for tight spaces. These tools keep the mic near the speaker and stop handling noise.
Pro Tip: Pair boompoles with shotgun mics to focus on voices and block background sounds.
Shock Mounts: Pearstone DUSM-1 Universal Shock Mount
Shock mounts stop vibrations from affecting microphones. The Pearstone DUSM-1 Universal Shock Mount works well to reduce unwanted noise. It keeps the mic steady, even in busy settings.
-
Good placement avoids sound problems.
-
Vibrations from stands or surfaces won’t ruin your recording.
-
Small distance changes affect sound levels, so stability matters.
C-Stands or Light Stands
C-stands and light stands hold microphones firmly during interviews. They are adjustable and work for many setups. Use them to position microphones at the right height and angle for clear sound.
Audio Recorders for Great Sound
What to Look For
Good audio recorders help you get clear sound. Choose ones with:
-
48 kHz and 24-bit depth for high-quality audio.
-
Easy controls for quick changes during interviews.
-
Battery power with USB charging for long use.
-
WAV file support to keep sound clear.
-
Headphone jacks to check sound while recording.
Suggested Model: Tascam DR-40
The Tascam DR-40 is a great pick for interviews. It records clear audio, has dual XLR inputs, and lets you monitor live. It’s portable and simple to use, perfect for any interview setup.
Cables and Extras

Phantom Power for Microphones
Some microphones need phantom power to work. This feature keeps sound quality high. Many recorders, like the Tascam DR-40, have built-in phantom power for these microphones.
Tip 4: Techniques for Noise Reduction and Audio Optimization
Cutting Down Background Noise
Using Directional Microphones
Directional microphones help block unwanted sounds. They focus on sound from one direction, making them great for interviews. Cardioid microphones work well in noisy places. They pick up sound from the front and reduce noise from the sides and back. Shotgun microphones are also useful outdoors. They capture the speaker’s voice clearly by focusing on a narrow area.
Pro Tip: Don’t use omnidirectional microphones for interviews. They pick up sounds from all directions, including background noise, which makes editing harder.
Keeping Away from Noise Sources
Place microphones far from noisy things like fans or air conditioners. Keep the mic close to the speaker for clearer sound. If recording outside, face away from the wind. Use a windscreen to block wind noise and improve audio quality.
Improving Audio Levels
Listening While Recording
Listen to the audio as you record using headphones. This helps you catch problems like overlapping sounds early. Fix microphone placement or settings to keep the sound clear. Many audio recorders have headphone jacks for live monitoring.
Setting Gain Levels
Gain controls how sensitive the microphone is. Too much gain makes sound distorted, while too little makes it too quiet. Adjust gain so loud parts stay clear without peaking. Tools like the Tascam DR-40 let you fine-tune gain for better results.
Backup Audio Plans
Using Lavalier Microphones
Lavalier microphones are great backups. Clip one to the speaker’s clothes, even if you’re using another mic. This gives you a second audio source if the main mic stops working.
Recording Separate Tracks
Record each microphone on its own track. This lets you fix sound issues like overlapping noises during editing. Multi-track recording makes it easier to adjust levels and improve clarity. Many audio recorders support this feature.
Pro Tip: Test your setup before starting. Make sure all microphones and tracks work properly.
