Just wanted to share an Ozone 5 story...
I'm no mastering engineer, but like more and more musicians these days, I'm producing and distributing my own work. That's why I was a little surprised when an instrumentalist I'd used on some past work asked me if I wouldn't mind "mastering" a CD he was producing. His style couldn't be more different from mine--Americana oldtime stringband music recorded in a single day around a stereo pair of mics in an X-pattern. But his budget was $0 and I was more than happy to spend a few hours helping out a friend.
His goal was to produce a master CD-R to be mass-produced for distribution at his band's shows. He had a specific sound he wanted to attain and knew exactly what he wanted--it was very old-timey to my ears, so different from the digitally (over-) produced music I write.
So I pulled up CD Architect, a tool I'd honestly never really used (came with Sound Forge Pro) and we arranged the tracks. But despite the fact that they were all recorded in the same session, because of slight changes in the position of the instruments and singers each track sounded different. The volume levels weren't matched, and worse, the tonal qualities weren't consistent.
Within the first 10-20 minutes we had a good basic preset built in Ozone using a combination of 3-band dynamics and IRC3 that brought all of the songs much closer in line with each other. After that we honed in on the remaining tonal balance issues and it was a breeze to pick the best sounding song and then use matching EQ to even out the tracks on the CD. All told, it took under two hours for about 35 minutes of content. He walked away with a test CD that he'll live with for a few days before the final pass.
It was enjoyable to work on music that was so incredibly different in every way from mine to give me an appreciation and level of objectivity I don't have with my own music... and to work on a whole CD project at once, rather than releasing one song at a time which is typically how I work.
