I have friends who use Logic and obviously they let me know how good it is and what you can do with it. However they say if I want/need help to mix and master I should come over to the dark side (lack of knowledge on Logic).
 
I know a few people that could do the job for me but I really don't know anyone that could do it on this format.
 
So I have been racking my brain then I remembered that I used to frequent these forums and thought I would ask if they're any UK based producers/engineers who could help me. My music style is predominantly contemporary. so if there is anyone willing to work with/longside me or to help out I would be grateful. I'm based in the west Midlands Area but frequent London quite alot so travel is not a problem.
 
Things have changed here quite a bit, haven't really got time to sit and search through the forums like I used to. It is a bit much and can be quite taxing. So whether I posted in the right section I am not sure. Here I am
 
ps. This doesn't have to be the longest post in history short and concise!

In my opinion, Logic isn't Mastering software, only Mixing. Not that you can't Master with it. However, there's lots that you need specific tools for Mastering, and Logic likely doesn't have many of them. I'm sounding off snooty here, but one can appreciate a bit of snootiness when they're being peer-pressured into a different DAW for Mixing/Mastering, but have some doubt.
 
All of the major players do the job. It's a matter of portability, convenience, and knowledge of how to use those tools. With that said, the parts that matter most (the sound) are typically DAW-independent. So, don't let someone sway you to the dark side because it's what they love. Now, if they believe Logic is the best thing to Master with, ask them to take a look at Wavelab 8. If they can show that Logic can do everything Wavelab can for Mastering, then I'll Pepsi-challenge that one in a heartbeat. However, if they believe Logic is better than Sonar for Mixing, that's pure subjectivity and experience. You show me a guy who knows Logic and uses it with ease, and we can introduce you to Brandon, Fast_Biker_Boy, or some of the peeps here that are killer Sonar aficionados. I'm just having fun here, but you get the general idea. It's about what you feel is best for you. 
 
Best of Luck!!

You can mix and master or any software program. You do not need to buy Logic to mix and master.
 
Its not what you have. Its how you use them. That's according to my wife anyways. I don't know what she means when she tells me that????

The OP's problem seems to be that he does not have the skill himself to use Sonar for mastering, and that he does not know anyone who has the skills needed who knows how to use Sonar for that purpose. So the suggestion to use another DAW seems to be one of convenience for the skilled mastering guy he is looking for. This is a real problem with using totally capable software like Sonar, which is not the first choice for many professional engineers, compounded by the proprietary file formats that keep different DAW's from being easily . It is doubtful that large numbers of highly skilled Logic users are going to switch to Sonar. If he is really at the mastering phase, it is not too problematic, as he can ship his mastering consultant wav file stems of his mix to be used in whatever DAW the guru is competent on. Mixing is more likely to benefit from running the original tracks in Sonar, and keeping everything editable until the mix is done.

If he is sending stems its not mastering. Its mixing.  I think people need to do a little reading on the subject. it is not that hard. Ans yes Sonar can do it as can any DAW. In fact Sound Forged was highly recommended for just that purpose many years ago. Back then it was not multi track capable. 
 
Most mastering houses require a stereo file. 
 
 

I think people misunderstand the appropriate definition of Mastering. Mastering is the process of taking finalized audio and producing a pressing plate. Creating a Master stamper. Incidentally, over the years, a Mastering Engineer's role has grown to encompass making things simply sound better than before. There are Mastering houses that will take stems. The idea there is mainly for ensuring that some Mastering decisions don't affect the vocal, or that the vocal survive the compression/limiting techniques used.
 
However, there's Mastering Engineers that will receive entire mixes in a DAW. It's the least recommended way to Master, but in fact, is the most flexible. The Mastering engineer isn't there to make mixing decisions, but rather to adjust specific things that tend to change during the Mastering process. Stems aren't Mastering, but Mastering can be done with stems.

If I was mastering, I'd use Samplitude.

Wavelab is my choice because of the Mastering-centric functions, metering, rendering, and other encoding tools it has. It's geared for Mastering.
