Thank you all for your nice comments Fickle, Brenski and PiotreQ. They give me desires to keep on with this project.
To do this I split every track into four channels, working with both stereo channels from the backing track and both from the voice with the Adobe Audition 3.0. That the way I can manage to make panning.
I aplied a slightly noise reduction to all songs because all the songs of the 2011 remasters have an annoying hiss on the back. But I didn't removed it completely to not loose much treble of the songs.
For every album, the best song to listen to this horrible hiss are (notice the beggining):
Queen - Liar
Queen II - TMoTBQ (FtS was ruined due the heavy clipping (2:05 - 4:00))
SHA - Tenement Funster
ANatO - Sweet Lady
ADatR - You and I
NOtW - SHA (WATC was ruined too, the last chorus (2:34!)WEE EAHGOSA THE GHKAHDMPCINSONS)
Jazz - Mostly Fun It, but all.
Game - Don't Try Suicide
Flash - Flash's Theme
Space - Soul Brother
Works - ITtWWC?
AKoM - WWtLF
Miracle - Stealin'
Innuendo - Don't Try so Hard
MIH - IWBtLY
Again, I really tahnk you three for your comments, (it might sound stupid, but they made me happy). That's why the responses are very important.
Here I let you Leaving Home Ain't Easy. And the list of changes:
-Raised up hi-hat and general trebles.
-Added more body to the lead voice and raised up it's volume.
-Lowered down the "S!" from "But I have to SSSay" at 1:15.
-Raised up the acoustic guitar shine.
-Raised up a bit the toms "bum!".
-Eliminated a light constant clicks from the whole ethereal voice part, every time Brian sings.
-Reduced every "s" intensity on that entire part.
-Added stereo effects to all that part, so it's more balanced and the hi-hat not only sounds by the right channel.
-Eliminated the high clipping when this part ends and the back vocals sings "Leaving home ain't easy", at 2:12.
-Reduced the "s" intensity of the last part with the backing vocals at 2:37.
-Added stereo effects to the ending guitar.
-Eliminated ugly noise on the very end guitars, at the fade out part.
In general the volume levels of the instruments are very good, the backing vocals aren't so strong like in Dreamer's Ball and doesn't make the lead vocal be on second place.
Enjoy it too!
