The device also houses an omnidirectional microphone
, a mini speaker and real-time face tracking using a front facing camera.

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
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.
As part of the solution, the PolycomA SoundStructureA audio system has an automatic microphone mixer with feedback elimination and acoustic echo cancellation to eliminate howling and echoing that occurs with an omnidirectional microphone
in the on-premises public address system.
