Just ran mp3gain (1.2) and after running album gain, one of my mp3's is listed in a blue font, with blue question marks in the clipping columns
What does this mean?
Oddly, the analysis shows that the volume was 142.7 dB before normalising...
Full Version: blue question marks in mp3gain
Abnormally loud or abnormally quiet, I have found. It has happened on Thomas Newman Film soundtracks and recordings I made in a forest... My interest lies in what the album is and what song managed to get the unofficial highest ever volume 
to me this happened when MP3Gain was not able to apply gain correctly. After MP3Gain the file seems to be corrupted and it shows at least one extremely loud "blip" at > +20 dB.
The MP3 level tool by Sergej Sapelin (don't remember the name) says in this case, it is not able to correct the volume and leaves the file alone without damaging it.
Edit: the name is MP3Amp

well the tune is a live Black Uhuru track, but it was never tons louder than the others on the album
also the normalised file still plays fine, althoug I can't really say if it was normalised or not - mp3gain seems to think it did normalise it

If there is a ??? in the clipping column for a file, then the mp3 probably has some bad data in it. This bad data could have been caused by a download error, a poor job of splicing two mp3s into one, or other factors. Listen closely to the mp3, and somewhere you'll probably be able to hear a loud click, pop, “chk”, or other sound. Because of this bad data, the program cannot accurately determine the maximum amplitude, because the bad data is causing extreme clipping.
Fortunately, in most cases the amount of bad data is small enough that it does not affect the calculation of the overall volume of the file. The suggested Track and Album gains are probably still valid.
