In Windows 95, 98 and Me, the DirectSound mixer component and the sound card drivers were both implemented as a kernel-mode VxD driver (Dsound.vxd), allowing direct access to the primary buffer used by the audio hardware and thus, providing the lowest possible latency between the user-mode API and the underlying hardware, but in some cases ...
Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets.Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput.
Audio Stream Input/Output (ASIO) is a computer audio interface driver protocol for digital audio specified by Steinberg, providing high data throughput, synchronization, and low latency between a software application and a computer's audio interface or sound card. [1]
The buffer in an audio controller is a ring buffer. If an underrun occurs and the audio controller is not stopped, it will either keep repeating the sound contained in the buffer, or output silence depending on the implementation. Such effect is commonly referred to as "machinegun" or Max Headroom stuttering effect.
Low Latency High-Definition Audio Codec (LHDC) is an audio codec technology developed by Savitech.LHDC allows high-resolution audio streaming over Bluetooth.It is a high-quality Bluetooth codec based on the A2DP Bluetooth protocol and allows a bit-rate of up to 900 kbit/s compared to SBC's bit rate of 345 kbit/s .
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.
While standard web conferencing software is designed to facilitate remote audio and video communication, it has too much latency for live musical performance. [ 1 ] [ 2 ] Connection-oriented Internet protocols subject audio signals to delays and other interference which presents a problem for keeping latency low enough for musicians to play ...
If the sound source is 340 meters from the microphone, then the sound arrives approximately 1 second later than the light. The AV-sync delay increases with distance. During mixing of video clips normally either the audio or video needs to be delayed so they are synchronized. The AV-sync delay is static but can vary with the individual clip.
