View Full Version : Audio input to Squeezebox possible?

With the current hardware on the Squeezebox, would it be possible in the
future for the software to take an audio input on one of the available
connections, and stream the audio out to the network, or would this require
hardware changes?

It would be really cool for the whole-house audio distribution end of
things.

Squeezebox is not designed to do this. Reading the follow-ups to this
thread, I would also point out that IMHO such a feature, nifty though
it may be, is not as useful as one might initially think. The reason is
that for the most interesting applications like musical instruments,
live DJ, or any kind of multi-room distribution from a live source, you
have the problem of not being able to transmit over the network
reliably without a significant amount of delay (so you can recover lost
data). When streaming from a "stored" source, this is not a problem
because you just pull through as much data initially as you need to
fill the buffer. However, if you want good quality (no clicks /
dropouts) from a live source, you have to delay it for a second or so -
more for wireless.

BTW, Gibson is developing a system for guitars, and soon other
instruments, which is designed to do this over switched ethernet with
minimal latency. The thing about switched ethernet is that it really is
"damn near lossless" - if you can assume such a reliable network
(definitely not wireless), and do not provide for retransmission, it is
possible to get the latency down to almost nothing. They're using very
customized hardware and network protocols for this... cool stuff:
