The MPEG-4 Low Delay Audio Coder (a.k.a. AAC Low Delay, or AAC-LD) is audio compression standard designed to combine the advantages of perceptual audio coding with the low delay necessary for two-way communication. It is closely derived from the MPEG-2 Advanced Audio Coding (AAC) standard.
If the delay is fairly significant (more than a few hundred milliseconds), it is considered annoying. If the delay is very small (tens of milliseconds or less [3]), the phenomenon is called sidetone. If the delay is slightly longer, around 50 milliseconds, humans cannot hear the echo as a distinct sound, but instead hear a chorus effect. [3]
ASIO 2.3 introduced monitoring for dropouts in the audio stream. [4] ASIO bypasses the normal audio path from a user application through layers of intermediary operating system software so that an application connects directly to the sound card hardware. Each layer that is bypassed means a reduction in latency (the delay between an application ...
To their credit, though, Devantier tells me Samsung has done a lot of work on this problem over the past few years, and 2020 models now have the ability to adjust its delay in both directions ...
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.
Unfortunately, video delays frequently make quick and large changes, for example, a jump in delay time from 2 seconds to 6 seconds is possible. To maintain proper audio-video sync, the audio delay must track these video delay changes. Changing the audio delay requires changing the difference between the write address and the read address.

If the secondary does not implement the mode, it responds with DM or FRMR. Set ... mode extended (SNRME, SARME, SABME) command Place the secondary in the specified mode, with 7-bit sequence numbers (2-byte control field). Set mode (SM) command Generic mode set, new in ISO/IEC 13239, using an information field to select parameters.
