Sorry about that. I was pretty sure I cc-ed you, but apparently did
not.

Debian 7.7: mpg123, anything pyaudio based, at least. (install
python-pyaudio, try to run examples).

I hit it with:

#!/usr/bin/env python

# Public Domain

# Deps: PyAudio, NumPy, and Matplotlib

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import pyaudio
import struct
import wave
...

When I decided to investigate.
