The iPad is an iPadOS-based (previously iOS) line of tablet computers designed and developed by Apple Inc.; it has a wide variety of accessories made by Apple available for it, including a screen cover specifically for the respective models of iPad called Smart Cover, as well as a number of accessories to allow the iPad to connect to other devices, some of which enable non-touchscreen input.
The iPad Mini 2 (formerly marketed as the iPad mini with Retina display, [2] officially iPad mini 2 with Retina display [3]) is a tablet computer designed and marketed by Apple Inc. It has a nearly identical design to its predecessor, the first-generation iPad Mini , but features internal revisions such as the use of an A7 system-on-a-chip and ...
The Smart Cover, introduced with the iPad 2, is a screen protector that magnetically attaches to the face of the iPad. A smaller version is now available for iPad Mini. The cover has three folds, which allow it to convert into a stand, held together by magnets. [24]
FreeSync is an adaptive synchronization technology that allows LCD and OLED displays to support a variable refresh rate aimed at avoiding tearing and reducing stuttering caused by misalignment between the screen's refresh rate and the content's frame rate.

A video camera with built-in microphones or line-in may not delay sound and video paths by the same amount. Solid-state video cameras (e.g. charge-coupled device (CCD) and CMOS image sensors) can delay the video signal by one or more frames. Audio and video signal processing circuitry exists with significant (and potentially non-constant ...
Example: A 16-bit system has 2 16 different possibilities, from 0 – 65,535. The smallest signal without dithering is 1, so the number of different levels is one less, 2 16 − 1. So for a 16-bit digital system, the Dynamic Range is 20·log(2 16 − 1) ≈ 96 dB. Sample accuracy/synchronisation Not as much a specification as an ability.
The frequency range of these drivers is maximized through the use of a whizzer cone and other means. Most single driver systems, such as those in radios, or small computer speaker designs, cannot reproduce all of the audible frequencies or the entire audible audio range (i.e., sound within the range of human hearing).
