I haven't read all the replies thoroughly, so forgive me if I'm repeating information.
This thread caught my attention because I just finished a 19 track CD of my own music. It was 6 years in the making, but it's finally done.
Sound Forge is meant to be paired with CD Architect in my opinion. You create the regions in a track with Sound Forge, then when you export that file in to CD Architect, you can easily create tracks at those regions. You can do the regions directly in CD Architect too and skip SF all together.
This method is extremely handy for when you rip LP's so it sounds like the LP is playing nonstop with no dropouts of pops and clicks between tracks, yet you can still skip songs if you want to.
I spent days mastering my CD. I loaded all 19 .wav's in to CD Architect. I loaded all kinds of effects on each track thinking I would need to spice things up, but I couldn't get it to sound right. Finally I said to myself, why am I doing this? I spent 6 years on this music getting it to sound the way I want and now I'm adding more to each track?
Point behind this is, you should have to do very little when you get to the CD mastering point. If you have to do more than slight compression, adjust some gain due to track volume differences, and some light Mastering EQ, then you're not done with the actual mastering stage. There's a difference between Mastering and CD Mastering. Now that I think about it, even slight compression is questionable at the CD Mastering stage.
If you have Sound Forge, there are some sweet tools that come with it that you can also use in CD Architect. All I ended up using was the free Izotope Limiter and the Sony Master EQ that comes with Sound Forge, on the Master Bus. I did have to EQ two of the tracks so I removed them, adjust the mix in Sonar, and used the new file. I know it sounds like a lot of work, but that's technically what should be done and makes for a smoother process if I want to add songs to the CD in the future and don't have the CD Architect project file.
With CD Architect you have a visual representation of the volume of each track and can control the volume or gain. Gain is what you want since it will effect the input side of the effects on your master bus.
I rolled off the Master EQ at 80Hz and 15kHz, found the softest track and adjust the gain down to match it on all the others, put the Izotope Limiter on set to -2.0 and adjust it to barely hit -2.0.
If you have to EQ individual tracks, most of Sonars plug-in's work in Sound Forge and CD Architect. 32-bit only though. I used Sonitus EQ on a couple of tracks but then, like I said before, I remastered the tracks in Sonar and used the new file. But I would have been perfectly fine using Sonitus inside CD Architect.
Sony Master EQ ... check it out. 32-bit only, but I'm ok with that for the sound I get with it.
Oh, the other thing ... I'm not comfortable with the way Sound Forge and CD Architect do dithering, so I used 44.1/16 files. If you want to use higher spec files, you'll also have to throw dithering on the master buss in CD Architect.
CD Architect comes with Sound Forge ... you should have it ...
Hope this helps.
