The device also houses an omnidirectional microphone
, a mini speaker and real-time face tracking using a front facing camera.
The system's configuration was the same in all cases: a rectangular room 3 m wide by 3.6 m long; in the center of the room, the prototype is localized comprised of two omnidirectional microphones
in contraposition separated 15 cm from each other; a voice recognition unit with omnidirectional microphone
; and a control unit supported by a microcontroller (ATmega 2560 from Atmel).
When functioning as a wireless speakerphone for phone calls and video chats, the Jambox offers a built-in, omnidirectional microphone
with echo-cancellation that's compatible with most Bluetooth-enabled devices.
Additionally, subjects could have preferred the omnidirectional microphone
condition because of the greater access to environmental cues that was likely afforded in this program.
The headset delivers a frequency response of 15-25,000 Hz and an omnidirectional microphone
features a frequency response of 30-16,000 Hz and has high sensitivity for optimum pickup.
There is an inbuilt omnidirectional microphone
with a decent range and good clarity (I could talk in a market with the microphone several inches away from my mouth, and the person on the other side could hear clearly).

Other features include a flying erasehead for clean scene-to-scene transitions, a quarter-inch charge-coupled device solid state pickup with 70,000 pixels, high-speed picture search, blank search, real-time tape counter, battery charger with refresh capability, and built-in omnidirectional microphone
. Included accessories are a power connection cord, A-V output cable, rechargeable NiCad battery,
The latter comes integrated with a 12-watt amplified stereo keyboard, 20-W speakers, LED display, volume, bass, left and right channel controls, omnidirectional microphone
, and phone jacks.
Launching at an unprecedented industry price point of $895, PanaCast 3 uses three 13-megapixel cameras working as one via the PanaCast Vision Processor to capture the entire room on video, a digital signal processor and two omnidirectional microphones
with 40% better separation for enhanced audio and an advanced multi-sensor AI array that has built-in capabilities to detect people.
Fitted with omnidirectional microphones
on either ear, they capture the world around you, creating an immersive 3D soundscape accurate to the environment the user inhabits.
