VoxCast

Drone-Mounted Audio Broadcast System

VoxCast is a high-output aerial loudspeaker payload designed for clear voice projection during outdoor operations. It streams live audio from a nearby device over Bluetooth and projects it downward over the incident area.

What it does

• Broadcasts live audio from a phone, tablet, or command device
• Projects sound downward over crowds, terrain, or incident zones
• Enables standoff communication without moving personnel closer

Why it’s different

• Airborne delivery reaches areas vehicles and handheld PAs can’t
• Live input over Bluetooth (not limited to prerecorded clips)
• Voice-first tuning for intelligibility in outdoor noise

Performance Overview

Audio Performance

• Maximum Acoustic Output
  • Tuned for speech intelligibility under outdoor conditions
  • Designed for sustained output without harsh distortion
• Effective Voice Projection (Typical)
  • 50–75 ft AGL: clear voice within ~150–250 ft radius
  • 100–150 ft AGL: intelligible commands within ~300–400 ft radius
• Directional Behavior
  • Downward-biased projection for ground focus
  • Reduced horizontal spill compared to vehicle PA systems

Audio Input & Control

• Input: Live Bluetooth audio stream
• Sources: Phone, tablet, laptop, or command device
• Latency: Low-latency voice transmission suitable for real-time commands

Operational Impact

• Issue instructions without entering hazardous or restricted areas
• Reach crowds or individuals beyond megaphone / vehicle PA range
• Maintain standoff distance while retaining clear command presence

Power & Endurance

• Power: Drone-powered payload system
• Runtime: Sustained broadcast during typical flight durations
• Thermal Handling: Designed for continuous output under load
