  2. Audio-to-video synchronization - Wikipedia

    en.wikipedia.org/wiki/Audio-to-video_synchronization

    The AV-sync delay is static but can vary with the individual clip. Video editing effects can delay video causing it to lag the audio. Transmission (broadcasting), reception and playback that can get introduce AV-sync errors. A video camera with built-in microphones or line-in may not delay sound and video paths by the same amount.

  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 sound in the transmission medium.

  4. 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.

  6. Digital delay line - Wikipedia

    en.wikipedia.org/wiki/Digital_delay_line

    A digital delay line (or simply delay line, also called delay filter) is a discrete element in a digital filter, which allows a signal to be delayed by a number of samples. Delay lines are commonly used to delay audio signals feeding loudspeakers to compensate for the speed of sound in air, and to align video signals with accompanying audio ...

  7. Head-related transfer function - Wikipedia

    en.wikipedia.org/wiki/Head-related_transfer_function

    HRTF filtering effect. A head-related transfer function (HRTF) is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others.
