simple toolset for broadcasting live audio

 It sends and receives encoded audio over IP networks, via a soundcard
 or audio interface. It can be used for point-to-point audio links or
 multicast, eg. private transmitter links for a radio station or other
 live audio distribution. In contrast to traditional streaming, high
 quality wideband audio (such as music) can be sent with low-latency,
 typically as low as a few milliseconds, and incredibly fast recovery
 from dropouts.
 .
 It works favourable as a replacement for traditional ISDN lines and
 hardware ISDN codecs.
