The present disclosure provides techniques for controlling transmissions in time-sensitive networks (TSNs) and/or for time-sensitive applications (TSAs), including techniques for providing low latency and scalable gate control for TSNs and TSAs, configuring multiple TSAs to share the same physical network link, and enabling TSNs/TSAs to utilize Energy Efficient Ethernet (EEE) mechanisms.

Technologies for configuring and reducing resource consumption in time-aware networks and time-sensitive applications

Example methods, apparatus, systems and articles of manufacture to reduce audio streaming latency between audio and Gigabit Ethernet subsystems are disclosed herein. An example integrated circuit disclosed herein to process an audio stream associated with an endpoint device on a network includes an Ethernet subsystem to access the network and an audio subsystem to process audio data associated with the audio stream. The disclosed example integrated circuit also includes a direct hardware path between the Ethernet subsystem and the audio subsystem to exchange audio data between the Ethernet subsystem and the audio subsystem without the audio data being processed by a first software driver that is to provide access to the Ethernet subsystem or a second software driver that is to provide access to the audio subsystem.

Methods and apparatus to reduce audio streaming latency between audio and Gigabit Ethernet subsystems

Various embodiments relate to a system for adapting a signal gain, which comprises a peak detector configured to receive an audio input signal containing consecutive signal blocks and to dynamically establish a current input signal level of the audio input signal, and a loudness determination unit configured to dynamically determine a perceived loudness of a current signal block of the audio input signal based on a psycho-acoustic model of a human hearing. Furthermore the system comprises a time constant generation unit configured to determine a time constant based on the perceived loudness of the current signal block and the perceived loudness of a preceding signal block, wherein the time constant describing a change of the signal gain. A gain determination unit is configured to determine the signal gain for the current signal block based on the time constant and the current input signal level.

Peak detection when adapting a signal gain based on signal loudness

A system and method for switching between multiple audio input signals to select one of the audio input signals as audio output signal are disclosed which include receiving the audio input signals, receiving a control signal, and switching controlled by the control signal from a first one of the audio input signals to a second one of the audio input signals. Prior to switching, the first one of the audio input signals is muted and upon switching, the second one of the audio input signals is unmuted in one of multiple unmute modes based on one or more signal parameters characterizing the second one of the audio input signals.
