Re: [Bluemusic-users] python script and soundfile lengths

[Steven Y. <ste...@gm...>]

Hi Peiman,

Because you are using the python object, you can use Java classes like
you would any other Python class.  I have in blue a utility class
called SoundFileUtilities which has a method which can, given a string
filename, return the duration of the soundfile.  This depends on the
soundFile being able to be read by JavaSound.  To use it, use this
code:

from blue.utility import SoundFileUtilities
dur = SoundFileUtilities.getDurationInSeconds("/path/to/file.wav")

If you are using AIFF or AIFC files, python has a built-in module that
I saw is in the Jython distribution called aifc:

http://docs.python.org/lib/module-aifc.html

There is a wave module in my python 2.5 distribution but I do not see
one with Jython.  You could try taking the wave.py file from a regular
python distribution and putting it in blue/lib/pythonLib or
~/.blue/pythonLib to see if it will run with Jython.

Hope that helps!
steven
