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.
Tired of laboriously re-recording dual vocal tracks, John Lennon asked Townsend if there was some way for the Beatles to get the sound of double-tracked vocals without doing the work. Townsend devised automatic double tracking (ADT). According to historian Mark Lewisohn, it was Lennon who first called the technique "flanging". Lennon asked ...
A video monitor with built-in speakers or line-out may not delay sound and video paths equally. Some video monitors contain internal user-adjustable audio delays to aid in correction of errors. Some transmission protocols like RTP require an out-of-band method for synchronizing media streams. In some RTP systems, each media stream has its own ...
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.
Audio transmitted over analog cables can be adversely affected by signal degradation due to electromagnetic interference, high-frequency attenuation, and voltage drop over long cable runs. Thanks to digital multiplexing , the cabling requirements for digital audio distribution are almost always reduced when compared to analog audio.
Audio network protocols are used to transfer signals from many sources, digitally over network cables. Subcategories This category has only the following subcategory.
Ford has gotten about 100 complaints from F-150 truck owners who say the speakers in their vehicles are emitting a loud, annoying noise that sounds like static, or glass shattering, and which ...
AoE provides a reliable backbone for any audio application, such as for large-scale sound reinforcement in stadiums, airports and convention centers, multiple studios or stages. While AoE bears a resemblance to voice over IP (VoIP) and audio over IP (AoIP), AoE is intended for high-fidelity , low-latency professional audio .
