I don't fully understand what do you exactly mean by rhythm and amplitude so 
correct me if i am wrong. If you refeer to the overall max wave amplitude and 
for rhythm  you refeer to tempo/BMP you wil find useful some examples in the 
source tarball or in the svn:

For reading a file and finding its maximum, this snippet is pretty close:
CLAM/examples/AudioFileReading_example.cxx

Extracting the tempo is not that easy. There is an example contributed by 
Fabien Gouyon and others available at:
CLAM/examples/TickExtractor/
