Apple showcases iPhone 16 audio and video testing facilities in Cupertino

Apple has opened its specialized laboratories in Cupertino to showcase the testing of the iPhone 16's audio and video features. A key focus is a long wave anechoic chamber, designed to eliminate echoes while testing the phone's four microphones. Engineers have developed a new microphone component to enhance audio quality. They also introduced the Audio Mix feature, allowing users to adjust recorded sounds creatively. Testing includes a spherical sound profile created by rotating the iPhone in a setup with multiple speakers. Additionally, Apple has a theater-sized video verification lab to calibrate display performance under various lighting conditions. This facility helps ensure videos look good on iPhone screens in different environments.
