EtherSound is one of several technologies for Audio over Ethernet( AoE). Developed by Digigram, EtherSound transmits digital audio and control signals over Ethernet.
EtherSound uses proven Ethernet technology, more correctly Fast Ethernet and Gigabit Ethernet, and uses EtherSound as the transport protocol on top of this technology. Using the underlying network and existing cabling, EtherSound can connect many transmitting and receiving devices in any combination. In total, EtherSound supports 64 synchronized channels over which pulse-coded digital audio can be transmitted at a sampling rate of 48 kHz and a resolution of 24 bits. At double the sampling rate, the number of channels is halved. In addition to the audio signals digitized in pulse code modulation( PCM), control signals and monitoring signals are embedded in the data stream.
EtherSound is fully compatible with IEEE 802.3 (x) and can be transmitted over Cat 5 and Cat 6 TP cables as well as over fiber optics, fiber optic links, switches, media converters or other Ethernet components. The prerequisites for transmitting high-quality audio are high bandwidth, the lowest possible latency, a defined quality of service( QoS) and no packet loss.
EtherSound, which is subject to licensing, is used by many well-known manufacturers of audio equipment, by system integrators, in audio broadcasting and in recording studios.
