Hi Sam:
1. how does one change there registration details
Click on "sgc3000000" to the left of your post, then under the "Modify Profile" tab, select "Account Settings".
2. what site would you suggest because i wanted to be able to talk to some professionals who had a high level of audio experience.
Those types of people are available here and elsewhere. The challenge involves acquiring a strong enough grasp of the fundamentals to be able to ask the right questions and understand the answers. I constantly study the basics of audio and this measurement forum documents portions of the empirical extension of that pursuit.
Searching the forums and reading posts related to what you want to learn about will help. Books are also very helpful. The single best source for learning the fundamentals is through an organization called Syn-Aud-Con. They have online instruction as well as live seminars that cost far less than they are worth.
3. would you be able to give me a link to the correct forum section?
If you mean within the PSW forums, that was answered at the end of my last post. If you mean an entirely different site, I'm only acquainted with forums that are similar to this one.
