using Linux executables from xBlock

[Robert M]

Is it possible to use executables from an xblock?

For example, call command line executable from python based xblock like this:

import os
os.system('sox input.wav -b 24 output.aiff rate -v -L -b 90 48k')

Where I assume I would have to include the executable in the xBlock to get it deployed.

Robert,

You can use any Python you like in your XBlock. You have to be careful not to depend on something that might not be present, or might change.

I'm curious about using an audio processing toolkit from an XBlock. What are you envisioning?

Down sampling audio before further use.
