Not really. If the forger converts a low-bitrate mp3 to WAV and then uses any popular encoder to make a higher bitrate mp3 out of this WAV, it will
look like an original high-bitrate rip even if it sounds probably slightly worse than the original low-bitrate mp3 (due to the two extra conversions).
In practice you can sometimes spot fakes by having a look at an album that you have downloaded from somebody with EncSpot and seeing if the details of all tracks are similar. When collecting albums from open networks people may end up with an
almost complete set of high-bitrate tracks and be tempted to 'upgrade' one or two lower bitrate tracks to make the set look nicer. These tracks often differ in some technical detail (ripping software, joint stereo, tagging etc) and suggest multiple sources instead of a single source original rip and a more thorough quality check is in place.
