It has become the standard for professional audio and video. 48 kHz is evenly divisible by 24, a common frame rate for media, such as film, unlike 44.1 kHz.
25.0 GB. 23.28 GiB. 90. Modern compact discs support a writing speed of 52× and higher, with some modern DVDs supporting speeds of up to 24×. [4] Writing a DVD at 1× (1 385 000 bytes per second) [5] is approximately 9 times faster than writing a CD at 1× (153 600 bytes per second). [6] However, the actual speeds depend on the type of data ...
