This is a simple audio monitor that records about 1/2 second of sound then immediately plays it back in a continuous loop.
If you are testing with a laptop's, (etc), internal microphone be aware that acoustic feedback might occur...
This could be a use for your now aging netbook... ;o)

#
# A very crude baby alarm or audio monitor using standard text mode Python.
#
# A simple program that will do a short record of sound from either the internal
# microphone or an external one and immediately replay it in a continuous loop.
# It should work on ANY version of Python for Linux from at least 2.0.1, but untested.
#
# This is similar to this Linux shell veraion:-
# guest:~$ cat /dev/dsp > /dev/dsp<CR>
# Except that the shell version generates a byte string 32768 bytes in size.
# Debian 6.0.0, /dev/dsp existing and Python 2.6.0, 2.7.2, 3.1.3...
# PCLinuxOS 2009, /dev/dsp existing and Python 2.5.2, 3.1.2...
# If /dev/dsp does not exist then install oss-compat from your distro's repository...
# It also assumes that the _MIXER_ is set up correctly...
#
# This is ALL there is to it...
#
# Have fun messing with the sound system in its basic mode... ;o)
