Seems to be a nice solution, although I'm a little afraid of using dynamic compression at the files.
I found normalize-audio (http://normalize.nongnu.org/) can compute the RMS level of a file, I though about taking this value and calculate the necessary gain and apply it by mean of the playgain field on mysql. I'm still wondering how is the best aproach to achieve it. Thanks once more!
