What is Shotgun Microphone?
A shotgun microphone is a highly directional microphone with a long, narrow pickup pattern that captures sound from directly in front while strongly rejecting audio from the sides. Named for their elongated tube shape, shotgun mics are designed to isolate audio from a specific source even in noisy environments.
Shotgun mics work using an interference tube—a slotted barrel that cancels out off-axis sound through phase cancellation. This makes them:
- Extremely directional: Tighter pickup than cardioid mics
- Great for distance: Can capture clear audio from several feet away
- Background noise rejection: Ideal for outdoor or noisy locations
| Use Case | Distance | Example Mic |
|---|---|---|
| Video podcast (on boom) | 2-3 feet | Rode NTG3 |
| Field recording | 3-6 feet | Sennheiser MKH 416 |
| Run-and-gun interviews | 1-3 feet | Rode VideoMic Pro |
Why It Matters
Shotgun microphones are essential for video podcasters who want professional audio without visible microphones in frame. Mounted on a boom arm just out of shot, a shotgun mic captures broadcast-quality voice while the speaker appears "wireless." They're also invaluable for field recording, on-location interviews, and any situation where you can't place a mic close to the speaker.
How to Use This in Dispatch
Position a shotgun mic 2-3 feet from the speaker, pointed directly at their mouth. For video podcasts, mount it on a boom arm or C-stand just above the frame. Shotgun mics require phantom power, so ensure your recorder or interface can supply 48V. In post-production, you may need to reduce room echo since shotgun mics can pick up reflections from surfaces they're pointed toward.
