Hi
I'd like to process samples, mostly slice, splice, mix and fade,
preferably in python, and preferably without any 3rd part library
installed. I couldn't find such functionality inside standard python,
did I overlook something?
I could (and have) write wrappers around sox, but since sox seems to
change it's "API" all the time that's not such a nice solution. I
guess/hope ecasound is more stable with regards to it's interface, would
that be a better option?
Are there other languages, c++ or c for instance that have the
functionality I'm looking for build in? I might consider letting go of
my beloved python if other languages have something available as standard...

Hallo!
Look at numpy and scipy (http://www.scipy.org/). Python is really well
suited for all those kinds of operations - similar to matlab.
I do all my signal processing and machine learning simulations in python
(instead of MATLAB/octave, as before).

Thanks for mentioning that, it look interresting, will check it out tonight!

Slightly more specialized, and does involve third-party libraries:
David Cournapeau's Audiolab is a wrapper around libsndfile, allowing
to read/write audio files from numpy arrays.

In Hernán Ordiales blog there are some informative examples about that:

Have you ever looked at The Snack Sound Toolkit ?
http://www.speech.kth.se/snack/
I don't think it is current even if it will meet your needs. Might be worth a
look if you don't find anything else.
all the best,

You can load and save samples in Python without any 3rd party module, using the
standard library: http://docs.python.org/library/mm.html. That said, I would
recommend that you use Audiolab instead, as mentionned on this thread.
Then, you do not need any API to perform such simple operations as slicing,
splicing, mixing and fading. All you need is a couple of loops, and a few
additions and multiplications.
