So, is there any reason NOT to go down to 83dB or 80dB?
@BFG: Are you going to play those MP3 in a player that supports replaygain, or in a player that does not.If you play them in a player that does not support replaygain, then you need mp3gain and there's the option to specify an alternate gain. It is up to you to decide if it is too silent or too loud with that new value.
There's also the possibility to scale during or prior to encoding instead of adjusting global gain after encoding. This is what I do.
I wrote "replaygain" when I meant "MP3Gain".
I rip to flac and use foobar2000 to add RG information. From there I encode mp3s:http://www.hydrogenaudio.org/forums/index....st&p=601287
Regarding lack of perfect reversibility, they're lossy files to begin with.
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.
