Thanks. We are interested on the kind of things you want to do with CLAM.

Does that happen with multichannel audio files? Maybe it is due to an 
configuration over restriction. You don't transfer other file parameters such 
as the samplerate.

A backtrace could be useful. You can generate it by running:

$ gdb ./MyProgram
(gdb) run parameter1 parameter2
Segmentation Fault ....
,,,,,
(gdb) bt
...Here, the backtrace will appear...

AudioFileIn and AudioFileOut are deprecated and i hope they get removed on the 
next release. The new-but-not-so-new classes were added to cope with mp3 and 
ogg particularities while keeping the old code working. Now all the 
AudioFileIn/Out user code has been removed.
