Composing programatically with Gstreamer

[stoffe]

Hello,

I am looking for some simple example on how to do some "composing" with Gstreamer: basically, taking a few simple sounds ("notes"), each from its own file (wav or mp3 or...), setting them to start at different, possibly overlapping, times with a pitch (and duration?) and write this out as a combined audio file.

I'm having trouble finding any good examples on how to do something like this. Not asking anyone to write it for me, but I'd be very thankful for any pointers or examples to start from. The language (mostly) doesn't matter, I'd be happy to see any example.

Can't you look at the source code of programs that do this already? http://audacity.sourceforge.net/

Err, well in theory that is of course possible, though there are better examples then, like Jokosher.

However, going through a large software project to extract those few tiny bits I need would take days, if I can find the correct info at all. If, on the other hand, someone had something minimal lying around, that would get me up and running within minutes.

If someone knows how to do this, it would really help. Thanks.
