Like most other audio over Ethernet technologies, Dante is primarily for professional, commercial applications. Most often, it is used in applications where a large number of audio channels must be transmitted over relatively long distances or to multiple locations. Digital audio provides several advantages over traditional analog audio ...

AES67 also defines audio sample format and sample rate, supported number of channels, as well as IP data packet size and latency/buffering requirements. The standard calls out several protocol options for device discovery but does not require any to be implemented.

AoE systems use a much higher bit rate (typically 1 Mbit/s per channel) and much lower latency (typically less than 10 milliseconds) than VoIP. AoE requires a high-performance network. Performance requirements may be met through use of a dedicated local area network (LAN) or virtual LAN (VLAN), overprovisioning or quality of service features.
The AES50 protocol supports 24-bit PCM audio and delta-sigma bistream formats (Direct Stream Digital), with sample rates that are a multiple of 44.1 or 48 kHz. The bandwidth of 100 Mbit/s allows 48 channels at 48 kHz sample rate, or 24 channels at 96 kHz sample rate. The latency is 6 samples at 96 kHz and 3 samples at 48 kHz, or 62.50 μs.
And in the U.S., the TV is now the No. 1 device for YouTube viewing — topping desktop and mobile — underscoring the platform’s growing presence in entertainment, according to Mohan.
Byte 1: indicates if the audio stream is stereo, mono or some other combination. bits 0–3: Indicates the relationship of the two channels; they might be unrelated audio data, a stereo pair, duplicated mono data, music and voice commentary, a stereo sum/difference code. bits 4–7: Used to indicate the format of the user channel word
