No, I'm not sure that the test suite produces 'exactly' the files  
that you're looking for, just that there are some examples of each.   
It seems that I missed the subtle details of your original request.

If you want to specify exactly what you are looking for - e.g. the  
exact same audio in 8, 16, and 24 bit so that you can listen to each  
version to compare amplitude, or multichannel / surround audio, then  
perhaps someone on this list has non-copyrighted material that they  
could send you.  I'm not sure that I have anything I can release.

You could always find similar example audio files in AIFF or WAV  
format, and then convert them to flac for your testing purposes.   
AIFF allows for multiple channels, although I have not tested whether  
it is a simple matter to convert to FLAC from multichannel files.

I thought the "test" part of the source was like a unit test for the
whole FLAC package and not exactly what I was looking for. I'm more
interrested in if diffent bit in flac files will still have the right
amplitude when I play my files in my implementationn, and if I'm mapping
multichannel files to the right speakers is done corrently in my

But what you're saying is that the test suite will generate such files
for me, that's great
