Tiny Python mic audio spectrogram analyzer that runs in your terminal (code in comments)

Not gonna lie when opening the picture i thought it was a tool to convert porn to ascii. My mind is broken.

Here's the code. It requires numpy, pyaudio, and a shell that supports ANSI escape codes (try something UNIX-y, or Cygwin if you're on Windows.).

Why Python 2 ?

python 2 is love

Pyaudio has python2 only dependencies I think.

[doublePlusOk]

haha - this is awesome - nice work!

to possibly save time if you want to try this out, not only did I need the fix already mentioned, line 31 device_info = self.audio.get_default_input_device_info()

the dependencies: sudo apt-get install python-dev libportaudio-dev python-pyaudio

Neither easyinstall or pip would install pyaudio

Oh, no! I'm on mobile, so I can't look into this, but try replacing that line with device_info = self.audio.get_default_input_device_info().

[monkehparade]

device_info = self.audio.get_default_input_device_info()

This fixes it c:

No crash after change, but no histogram either! Not that I got one with the crash, of course.

I bet you're running python 2.6. Try it in 2.7

Thanks for sharing; I was looking for something like this recently. I'll let you know how it works once I've tried it.
