Now before you go off the deep end, I just came across this and am still playing with it.
I was impressed with the analysis it does of your WAV or MP3 file and it actually seems to work.
It's got quite an extensive tool kit and a good assortment of reference audio files to bounce your source against.
I think it's worth exploring. It has a complete manual with it also.
I've mastered several of my songs with this tool and it is amazing.
There are reference files (over 200) that will master your song to that genre.
It can also master individual tracks, vocal, guitar, bass and there are reference files for this also.
You can also load up a file for just EQ or compression, bounce it against a reference file, and it will give suggestions for EQ and compression that you can then apply through whatever other tool you have.
It will produce a printable reference file that you can use.
Try it out and let me know what you think. :D
Master it with one of the @master rms. settings.
The @master ones seem to do the best job of not crunching out the middle.
Also, the reference files are definitely designed to beat up the loudness war and appear to be designed more to master multiple songs for use on a CD or album rendition.
P.S. Just my humble opinion but the auto mastered version separates the guitars and brings out the lead better.
It also set the loudness more along an AGC setting, keeping everything within a range.
