-# Implementation of the following:
-# 
-# 1. Setup ECI to read audio from file, apply a 100Hz lowpass filter, and 
-#    send it to the soundcard (/dev/dsp).
-# 2. Every second, check the current position. If the stream has
-#    been running for over 15 seconds, exit immediately. Also,
-#    every second, increase the lowpass filter's cutoff frequency
-#    by 500Hz.
-# 3. Stop the stream (if not already finished) and disconnect the 
-#    chainsetup. Print chain operator status info.
