I didn't consider this point, and its truly one to think about. But since major projects also use sndfile and mad (like ardour uses sndfile), and the use of them simplifies the code, I still favour them over using external apps.

Another thing, we should better open a sourceforge project for tX with svn.

I can swear that libsndfile doesn't leak memory when used correctly
regardless of file format used. I consider any memory leakage a 
bug which I will hunt down and fix. In addition, every single release
is run extensively under Valgrind and all issues fixed.
