Jacob,
You are ... Not quite going about this in the correct way.
You should install Distribute, available from http://pypi.python.org/pypi/distribute This will provide the setuptools package, which is used to install most modern Python packages.
Once this is done, navigate to the folder and run:
python setup.py install
which will actually install the library into your site-packages directory and add it to the global package registry. As for documentation, I must admit that sound_libs is limited, but here's the general idea:
Bass, the underlying library provides functions such as
BASS_ChannelPlay, which takes as an argument the handle of a channel to play. The library models a pseudo-OO structure, with output streams and recordings inheriting the methods of channels, so I followed this in my wrapper. So once you instantiate, for instance, a sound_lib.stream.FileStream object, you can then call play on this object and it will call BASS_ChannelPlay with the channel's handle, which the object stores upon instantiation. Furthermore, Bass has many getters and setters which I have replaced with Python properties--so instead of calling BASS_ChannelSetAttribute(<channel_handle>, BASS_AttribPan, -1.0)
you can just go:
channel.pan = -1
I hope this is enough to get you started, and if you have any more questions feel free to contact me off-list.

Ok, think figured it out since see that there's a main.py file in actual 
sound_lib subdirectory, so can copy that folder/directory over wherever and 
then reference it and the objects/modules under there from within python 
interpreter, using import statement, and see there's also a .chm help file 
there, so let me play around a bit.

Stay well

Ok, if I want to try implement use of your soundlib library, how do I get it to 
execute the setup.py code since when I tried it under python 2.7, I first had 
to change the first line to in fact import setup from distutils.core - as 
opposed to setuptools, but distutils.core doesn't seem to have any 
find_packages inside/underneath it?

Do I need to run this under a different version of python, or do I not really 
need to run setup.py to actually make use of this under python itsself, and in 
that case, which modules should I initially try importing then, and/or where 
should I copy the contents of the .gz file I downloaded to under python27's 
installation directory?

Sorry, but am still relatively new to python itsself, and hence am rather 
asking these questions.

Stay well

If you want to perform this programmatically, use my sound_lib package
http://hg.qwitter-client.net/sound_lib
And set the .pan property of the sound from -1 to 1 with 0 being the middle.
If you're looking to just modify sounds, grab Audacity (the 1.3 beta,
open the sound, and use I believe shift+p on the track, or effects,
pan... It likewise ranges from -1 to 1.

Hi,

It looks like Windows Recorder can't do this. I want to take a sound
and pan it to one side or the other. Is there a utility that can do
something like this?

Thanks.
