I use all that stuff too, but as I understand it that wasn't the question. The question was which
SONAR plug ins do you use. I believe it is possible now to get a really good master using only the plugs in Sonar, especially with the new Adaptive Limiter and Engineering Eq's etc.
In Ozone 7 Advanced we have chains. In TRacks we have chains. In Sonar we have chains or you can make your own.
After having used most of the others I believe you can do it in Sonar. It's mostly about knowing which chains to use in addition to how to set each plug in.
You can make your own mastering chain in Sonar.
Here's a basic example of a chain you could make that would cover a lot of material.
Dynamic EQ> Multiband Compressor>Post Compressor>Exciter>Post EQ> Adaptive Limiter
You can mix it up, you can copy other chains or use the existing chains in Sonar. No one says you can't make adjustments to existing chains.
To begin with you'll need a basic understanding of frequencies and how they interact.How they can cancel each other or how too much can make a track muddy. Also an understanding of limiters and compression. With respect to master volume RMS, LUFS, Average RMS, K-meter.
Lots of folks simply use a mastering application. It really doesn't take much more to do it the other way. Even if you still use Ozone or TRacks you can learn how to best manipulate them for maximum effect. Use good plug ins. Sonar has good plug ins.
