Try the MP3 Encoder list (CCed).

No, LAME doesn't provide such a functionality, and I don't know of a
program which offers this functionality. Maybe someone on the MP3
Encoder list knows such a program.

Besides the fact, that a mismatching checksum means the data is
worthless, it should be easy to write a short program after looking at
http://www.mp3-tech.org/programmer/frame_header.html which does what you
want (in case you aren't afraid to touch C, C++, Java, VBA, Perl, Kylix,
Python, Ruby or any other programming language).

Bye,
Alexander.
