The FLAC source code has several small example programs that demonstrate how to use the libraries.  The source is available on the 
download page, or can be 
checked out from git.  The examples complement the 
API documentation.
		
		Currently the examples show how to encode WAV files to FLAC and vice-versa using both libFLAC and libFLAC++.  Over time we'll be adding more examples.
