Used in television production and filmmaking post-production, a 2-pop is a 1 kHz tone that is one frame long and placed 2 seconds before the start of a program. It is a simple and effective method of ensuring synchronization between sound and picture in a video or film. [1] A 2-pop is typically placed at the end of a visual countdown. Only the ...

A loop can be created by a looper pedal, a device that records the signal from a guitar or other audio source and then plays the recorded passage over and over again. [ 13 ] In the early 1990s, dedicated digital devices were invented specifically for use in live looping , i.e. loops that are recorded in front of a live audience.

Hexadecimal time is the representation of the time of day as a hexadecimal number in the interval [0, 1). The day is divided into 10 16 (16 10 ) hexadecimal hours, each hour into 100 16 (256 10 ) hexadecimal minutes, and each minute into 10 16 (16 10 ) hexadecimal seconds.
The first dedicated loop device was the Paradis LOOP Delay. [6] The Paradis and other models had volatile memories, forcing composers to develop fresh loops live in front of their audiences — and thus, live looping came into existence. Roland and DigiTech loop pedals entered the market in 2001, around the same time DJ mixing gained popularity ...
Some 1980s 8-bit Commodore computers, such as the PET / VIC-20 / C64, had a jiffy of 1/60 second, which was not dependent on the mains AC or video vertical refresh rate. [9] A timer in the computer creates the 60 Hz rate, causing an interrupt service routine to be executed every 1/60 second, incrementing a 24-bit jiffy counter, scanning the ...
