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.
Audio Units (AU) are a system-level plug-in architecture provided by Core Audio in Apple's macOS and iOS operating systems. Audio Units are a set of application programming interface (API) services provided by the operating system to generate, process, receive, or otherwise manipulate streams of audio in near-real-time with minimal latency.
On displays with a fixed refresh rate, a frame can only be shown on the screen at specific intervals, evenly spaced apart. If a new frame is not ready when that interval arrives, then the old frame is held on screen until the next interval (stutter) or a mixture of the old frame and the completed part of the new frame is shown ().
A real-time analyzer (RTA) is a professional audio device that measures and displays the frequency spectrum of an audio signal; a spectrum analyzer that works in real time. An RTA can range from a small PDA -sized device to a rack-mounted hardware unit to software running on a laptop .
Core Audio is a low-level API for dealing with sound in Apple's macOS and iOS operating systems.It includes an implementation of the cross-platform OpenAL. [1]Apple's Core Audio documentation states that "in creating this new architecture on Mac OS X, Apple's objective in the audio space has been twofold.
Apple bundled a pair of model M7963 clear spherical/globe Sound Stick 2.1 based speakers with the Power Mac G4 Cube, which was released on July 19, 2000. They used a custom USB interface and originally worked with the G4 Cube, Power PCs and ADC/ADP monitor screens. They work right up to OSX 10.6.4 Snow Leopard.

It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz. [2] [3] [4] In air at atmospheric pressure, these represent sound waves with wavelengths of 17 metres (56 ft) to 1.7 centimetres (0.67 in).
