Absolute time code (ATC) is generally recorded in the subcode or control track region of any digital tape. This is the code that digital tape machines use to locate specific points on a tape for autolocation or other functions. In some machines, it is even used to synchronise the tape to other equipment. ATC is precisely accurate and usually conforms to the IEC standard which is easily converted to the more commercially used SMPTE time code. Unlike SMPTE, ATC always begins at zero at the beginning of a digital tape and increments one frame at a time until recording stops. Some DAT machines have the ability to function without ATC on a tape while others simply will not play a tape without it. These days, almost all machines record it automatically so it will always be on every tape.

In acoustics, the opposite of reflection. Sound waves are “absorbed” or soaked up by soft materials they encounter. Studio designers put this fact to work to control the problem of reflections coming back to the engineer’s ear and interfering with the primary audio coming from the monitors. The absorptive capabilities of various materials are rated with an “Absorption Coefficient.” Absorption Coefficient

Graphic accelerators function like application-specific microprocessors whose purpose is to work in conjunction with a PC’s host microprocessor to display graphics. In general, graphic accelerators control frame memory, colour processing, resolution, and display speed. With the advent of the high-speed local buses and higher clock rates, accelerators operate on 32-, 64-, and 128-bit pixel data.

A) The time required to receive valid data from a memory device following a read signal. b) This is the time it takes from when a disc command is sent until the disc reaches the data sector requested. Access time is a combination of latency, seek time, and the time it takes for the command to be issued. Access time is important in data intensive situations like hard disc recording, multimedia playback, and digital video applications.
Lower access times are better. Keeping your drives in good shape with periodic de-fragging, etc. will ensure that your drive is providing the fastest access times it can.

A) The coded data for a picture or block of sound and any stuffing (null values) that follows it. b) A coded representation of a presentation unit. In the case of audio, an access unit is the coded representation of an audio frame. In the case of video, an access unit includes all the coded data for a picture, and any stuffing that follows it, up to but not including the start of the next access unit. If a picture is not preceded by a group_start_code or a sequence_header_code, the access unit begins with a picture_start_code. If a picture is preceded by a group_start_code and/or a sequence_header_code, the access unit begins with the first byte of the first of these start codes. If it is the last picture preceding a sequence_end_code in the bit stream, all bytes between the last byte of the coded picture and the sequence_end_code (including the sequence_end_code) belong to the access unit.

One or more registers associated with the Arithmetic and Logic Unit (ALU), which temporarily store sums and other arithmetical and logical results of the ALU.

Full-duplex audio technology; used for the elimination of acoustically-coupled return echoes within a teleconference room. Note that all microphones connected to an AEC are active at all times. Consequently, as more microphones are added, the total transmitted noise level (caused by picking up room ambient noise) increases. See also Tail Time, Echo Suppresser, and Echo Return Loss Enhancement.
