iMac Pro also comes with four microphones with beamforming technology, a new 1080p FaceTime HD camera with enhanced low - light performance, and new speakers that are up to 50 percent louder. (ecoustics.com)
The new speaker also includes Dolby processing and omnidirectional audio for a sound boost, while the mic array comes with beamforming technology and noise cancellation so it can hear even whispers in noisy rooms (we've only had an Echo mistake random noise for the «Alexa» command once or twice).
