Re: a program to verify original rip bitrate?

You can't really tell, for sure, once it is converted to another format or bitrate.

There are some clues you can look for, like whether the spectrum is hard filtered from 16kHz up (or anywhere in that area.. 18kHz, etc) MP3 codecs will do that as part of the compression scheme. They do not always do that, though. It's an option. You can do MP3 without the lowpass filters, so again, there's no exact way to be sure.
