[QUOTE="Mark DeArman, post: 137532, member: 950"] Re: Garage Loudspeaker Lab Unless something has changed with CLIO, it does the direct transform and not matched filtering. The old linear X system only did stepped sine analysis, I haven't tried his new one. I just looked through the Praxis manual and it appears to just do the direct form also. I'm going to give a talk at the Seattle AES on March 12th about different affordable measurement systems and how they work and how to use them. I hope to get the power point slides uploaded so people can look at them next week. Here is the first parts, you can tell me what you think.

Oh I always forget, EASERA has a TDS module which cost extra and required the Firebox with a sync pin. So there is one. The main ones I'm going to look at right now are Smart/Sys-tune, REW, and I'll use my software as a sample of the matched filter type. I don't have a TEF or access to one. [/QUOTE]
