Hi All,
I was wondering if anyone here has experience in transmitting audio in digital format over twisted pair or cable (any sort). I am aware of some of the digital audio protocols like I2S, SDPIF and PCM out there but I am trying to bounce the idea around to see what is best for the given environment and required quality.
Rough requirements are:
Having looked at some available ICs out there, they are fairly fixed in either their speed, sampling frequency etc. not to sure about I2S where it may be possible to slow down the clock signal to the required speed.
Just an idea I am playing around and thought to ask, its really similar to a normal analogue PA system but I want a digital version.
Thanks,
Sean

Rough requirements are:
- simple serial protocol
- 16KHz sampling max, i.e. audio can be up to 8KHz for example
- transmission medium is cable
- robust enough to withstand some environmental/electrical noise in the operating area
- to be able to feed the serial audio up to 500 meters
