EtherSound

While Ethersound is compliant with the IEEE 802.3 physical layer standards, logically it uses a token passing scheme for transporting audio data which prevents all of its features from being used on a standard Ethernet network. On a standard network, it is only able to distribute audio and control data one way. It is not designed to share Ethernet LANs with typical office operations data or Internet traffic such as email. It supports two-way communications only when wired in a daisy chain topology.{{Cite web|title=Best Practices in Network Audio |publisher=Audio Engineering Society |year=2009 |url=http://www.aes.org/technical/documents/AESTD1003V1.pdf |accessdate=2010-05-05}} For this reason Ethersound is best used in applications suitable to a daisy chain network topology or in live sound applications that benefit from its low point-to-point latency.

Low latency is important for many users of audio over Ethernet technologies.{{citation |title=Studer, Digigram partner for connectivity |work=Television Broadcast |date=2007|url=https://www.highbeam.com/doc/1G1-167104123.html|archive-url=https://web.archive.org/web/20160910080852/https://www.highbeam.com/doc/1G1-167104123.html|url-status=dead|archive-date=2016-09-10}}One of the most critical applications involves picking up sound from a vocalist's or instrumentalist's microphone on a live performance stage, mixing that signal with those received from other microphones (and performers) and delivering the mix to the performer via in-ear monitors. Latency in this application is particularly annoying to vocalists. This is because a singer hears his or her own voice through bone conduction as well as through the outer ear. If the sound from the in-ear monitor lags the bone-conduction sound by more than a few milliseconds, phase shifts and comb filtering will become audible. EtherSound can deliver up to 64 channels of 48 kHz, 24-bit PCM audio data with a network latency of 125 microseconds.

If A/D and D/A conversions are included, this latency is about 1.5 milliseconds, the major part of

this latency being caused by the converters. Each device in a daisy-chain network adds 1.4 microseconds of latency.

EtherSound's network latency is stable and deterministic; The delay between any two devices on an EtherSound network can be calculated.
