  2. Loudspeaker time alignment - Wikipedia

    en.wikipedia.org/wiki/Loudspeaker_time_alignment

    Loudspeaker time-alignment, usually simply referred to as "time-alignment" or "Time-Align", is a term applied in loudspeaker systems which use multiple drivers (like woofer, mid-range and tweeter) to cover a wide audio range. It involves delaying the sound emanating from one or more drivers (greater than 2-way) to correct the transient response ...

  3. Delay (audio effect) - Wikipedia

    en.wikipedia.org/wiki/Delay_(audio_effect)

    Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio.

  4. 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.

  5. Line array - Wikipedia

    en.wikipedia.org/wiki/Line_array

    Manufacturers typically provide a spreadsheet or custom program to design arrays. Examples include L-Acoustics SOUNDVISION, [15] Adamson Blueprint, [16] Electro-Voice LAPS (Line Array Prediction Software), [17] d&b audiotechnik ArrayCalc, and JBL Vertec Line Array Calculator. [18] Renkus Heinz offers a program called EaseFocus.

  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. 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 ...

  9. Thiele/Small parameters - Wikipedia

    en.wikipedia.org/wiki/Thiele/Small_parameters

    A speaker that can handle 200 watts thermally at 200 Hz, may sometimes be damaged by only a few watts at some very low frequency, like 10 Hz. Power handling specifications are usually generated destructively, by long-term industry standard noise signals (IEC 268, for example) that filter out low frequencies and test only the thermal capability ...
