[LAU] sample processing in python

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... -- Atte http://atte.dk http://modlys.dk http://virb.com/atte
