Bob, As you know, the GUI has been a problem for many years - one the rare occasions I need the GUI I use IE.
As far as DRC is concerned, the correction impulse files, and how they are created, are critical. I might be wrong but I don't think REW creates these. There was a basic method that was described in the original Inguz instructions. I seem to remember that there was a Youtube video which someone did to demonstrate how to do this, so it might be worth looking for this. I did have a go using it but didn't get very far. For more control over the filter creation process there are two software packages that people have used (see below). They are expensive but they do give good results. The basic procedure is: - measure the room response (using a microphone and soundcard) - display the room response and create a target response - run the software to create the correction filters to use with Inguz - copy the correction filter wave files to the Inguz Impulses directory. In practice it is an iterative process - and people try different targets in order to get a final response which they feel is the most pleasing. Why not use a flat straight target? Well that doesn't necessarily work best for many people. One thing worth mentioning: sometimes a room will have a deep null (or near null) in the bass region - no DRC (or amplifier) can correct that. It will be caused by the room modes and the only solution is to move the listening position. I found that one incidental benefit of setting up DRC is that I had to start to scanning the room frequency response and that made me think about loudspeaker and listening positions. As a result I moved things around to make the frequency response smoother even before DRC. These are the software packages that were available a few years ago when I started looking at DRC. I use Acourate, Phil Leigh (who posted a lot on Inguz) used Audiolense. I have no idea to what extent they are currently being developed and there might be other options these days: AUDIOLENSE This comes in two versions: _Audiolense_2.0_ (165 Euro) - a more basic version which is very easy to use but has limited options. However this will be fine for most people with a stereo system. _Audiolense_XO_ (390 Euro) - a more advanced version with cross over design, etc, etc. Probably overkill. There is a trial version which enables you to create a corrected wave file that lasts 90 seconds, but you can't save your work. One advantage of Audiolense is that the room measurement is done within the main package, so you can see the result immediately. ACOURATE This costs 340 Euro. It is chock full of options which the non-expert will find totally confusing. However, once you get over the initial feeling of panic and follow the basic instructions it isn't so frightening. There isn't a trial version, but you can use download the measurement program for free and use that to measure the room response, send the impulse files to the developer together with a music clip of a few minutes and he will send you back a corrected version of the music clip. In either case - I'm not sure of the usefulness of the test files. They give some indication but, as I said, getting to a good result depends on trying various targets.
