This library adds Pure Data (Pd) objects that allow one to build a networking infrastructure within Pd on OSI-Layer 4 (transport layer). The objects use threads to allow for non-blocking network communication within an audio realtime environment. - [tcpreceive], [tcpsend]: unidirectional communication over TCP/IP - [tcpserver], [tcpclient]: bidirectional communication over TCP/IP - [udpreceive], [udpsend]: unidirectional communication over UDP - [udpsndrcv]: bidirectional communication over UDP - [udpsend~], [udpreceive~]: transmit uncompressed signals via UDP Since these objects only send/receive lists of bytes, you will most likely need to add some glue to implement higher-level protocols (and transmit meaningful data).
