Audio over Internet using OSC for Computer and Embedded Microcontroller

Up one level

Audio signals should be distributed to playback-systems over network. To save resources like bandwidth, and computing time the audio data should be sent on demand only. Ethernet established itself quite well in the field of controlling embedded devices and computer. Furthermore most of the available network-components are able to handle the IP-protocol. Open Sound Control (OSC) will be used as transmission protocol, due to its message based structure. Unfortunately there is no standardized implementation for audio via OSC yet. So with regard to the possibility of synchronicity and partly discontinuous data stream with constant and predictable latency a protocol to transmit audio over OSC has to be developed. As remote terminal microcomputers, embedded devices (e.g. microcontrollers) and computer-workstations with integrated ethernet interface are used.

Audio Over OSC on Embedded Devices
An open embedded plattform, escher2 with ADDA modules, should be expanded with the functionality of Audio over OSC using freeRTOS.
