- # 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!!!)
