Example program to read N channels of audio
|
|
data that are streamed over a TCP network
|
|
connection.
|
|
|
|
by Gary P. Scavone, 2000
|
|
|
|
NOTE: This program makes use of blocking audio
|
|
input/output routines. On systems where the
|
|
underlying audio API is based on a callback scheme
|
|
(Macintosh OS-X, Windows ASIO, and Linux JACK), these
|
|
routines are not fully robust (over/underruns can
|
|
happen with some frequency). See the STK tutorial
|
|
for example programs using callback schemes and/or
|
|
visit the RtAudio tutorial page
|
|
(http://music.mcgill.ca/~gary/rtaudio/) for more
|
|
information.
|
|
|
|
This program is currently written to play
|
|
the input data in realtime. However, it
|
|
is simple to replace the instance of
|
|
RtWvOut with WvOut for writing to a
|
|
soundfile.
|
|
|
|
The streamed data format is assumed to be
|
|
signed 16-bit integers. However, both
|
|
TcpWvIn and TcpWvOut can be initialized
|
|
to read/write any of the defined StkFormats.
|
|
|
|
The class TcpWvIn sets up a socket server
|
|
and waits for a connection. Therefore,
|
|
this program needs to be started before
|
|
the streaming client. This program will
|
|
terminate when the socket connection is
|
|
closed.
