Sorry for my bad english and greetings to everyone!

I am looking for a free tool that can check mp3 files and select the ones
that are "transcoded"; i.e. a 320-bitrate mp3 that was originally encoded as
a 192 ... or a 192 that was originally encoded as a 128 ... and so on. This
is not a simple problem, but i think that the rougly-bad transcoding are
simple to find ... if you know ... how ;-)

is there a tool like that i want?

What you seek is an impossibility.

Even if it existed, what good would it do you? Are you prepared to
delete any MP3s that may have been stupidly re-encoded to a higher bit
rate?

Might be semiempirical and fairly probabilistic, but likely not entirely
impossible.

Certain bit rates do generally correlate with an expected frequency
response, although also dependent upon initial recording factors.

Although not designed for the required purpose, this may help, at least
to some extent. Worth a try.

Good luck.
