  2. Rotation (music) - Wikipedia

    en.wikipedia.org/wiki/Rotation_(music)

    Even if a live person is present, the automation system at commercial stations usually picks the music ahead of time out of the current rotation, thus the DJ becomes only an announcer. Heavy rotation or power rotation is a list of songs that get the most airplay on a radio station. Songs in heavy rotation will be played many times in a 24-hour ...

  3. Latency (audio) - Wikipedia

    en.wikipedia.org/wiki/Latency_(audio)

    Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system, and when it emerges. Potential contributors to latency in an audio system include analog-to-digital conversion , buffering , digital signal processing , transmission time , digital-to-analog conversion , and the speed of ...

  4. Hard disk drive performance characteristics - Wikipedia

    en.wikipedia.org/wiki/Hard_disk_drive...

    It depends on the rotational speed of a disk (or spindle motor), measured in revolutions per minute (RPM). [5] [23] For most magnetic media-based drives, the average rotational latency is typically based on the empirical relation that the average latency in milliseconds for such a drive is one-half the rotational period.

  5. Latency (engineering) - Wikipedia

    en.wikipedia.org/wiki/Latency_(engineering)

    Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games. [1]

  6. Group delay and phase delay - Wikipedia

    en.wikipedia.org/wiki/Group_delay_and_phase_delay

    The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.

  7. Latency - Wikipedia

    en.wikipedia.org/wiki/Latency

    Latency (engineering), a measure of the time delay experienced by a system Latency (audio), the delay between the moment an audio signal is triggered and the moment it is produced or received; Mechanical latency

  8. Permutation (music) - Wikipedia

    en.wikipedia.org/wiki/Permutation_(music)

    Cyclical permutation (also called rotation) [9] is the maintenance of the original order of the tone row with the only change being the initial pitch class, with the original order following after. A secondary set may be considered a cyclical permutation beginning on the sixth member of a hexachordally combinatorial row.

  9. Disk storage - Wikipedia

    en.wikipedia.org/wiki/Disk_storage

    One is the rotation of the disks inside the device. The other is the side-to-side motion of the head across the disk as it moves between tracks. There are two types of disk rotation methods: constant linear velocity (used mainly in optical storage) varies the rotational speed of the optical disc depending upon the position of the head, and
