-## recordtest.py
-##
-## This is an example of a simple sound capture script.
-##
-## The script opens an ALSA pcm forsound capture. Set
-## various attributes of the capture, and reads in a loop,
-## writing the data to standard out.
-##
-## To test it out do the following:
-## python recordtest.py > out.raw # talk to the microphone
-## aplay -r 8000 -f S16_LE -c 1 out.raw
-
-import alsaaudio
-import sys
-import time

-# Open the device in nonblocking capture mode. The last argument could
-# just as well have been zero for blocking mode. Then we could have
-# left out the sleep call in the bottom of the loop
-inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE,alsaaudio.PCM_NONBLOCK)
-
-# Set attributes: Mono, 8000 Hz, 16 bit little endian samples
-inp.setchannels(1)
-inp.setrate(8000)
-inp.setformat(alsaaudio.PCM_FORMAT_S16_LE)

-# The period size controls the internal number of frames per period.
-# The significance of this parameter is documented in the ALSA api.
-# For our purposes, it is suficcient to know that reads from the device
-# will return this many frames. Each frame being 2 bytes long.
-# This means that the reads below will return either 320 bytes of data
-# or 0 bytes of data. The latter is possible because we are in nonblocking
-# mode.
