/*
Example program for realtime input/output
by Gary P. Scavone, 2000
by Gary P. Scavone, 2000.
This program reads N channels of realtime
audio input for a specified amount of time
and immediately play them back in realtime
(duplex mode). This program also demonstrates
the use of FIFO scheduling priority. To be
run with such priority, the program must be
set suid (chmod +s) and owned by root.
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.
