# Broadcast audio input on the network as UDP packets;

|
# they can be received on any SGI machine with "radio.py".

# This uses the input sampling rate, input source etc. set by apanel.
|
|
# It uses the default sample width and #channels (16 bit/sample stereo).
|
|
# (This is 192,000 Bytes at a sampling speed of 48 kHz, or ~137
|
|
# packets/second -- use with caution!!!)
