That's neat. How did you get that to show?
BTW, the Mac I'm using is old, still running 10.5 and cannot up updated to anything newer. But, it can sit at the MLP and be ready for measurements at a moment's notice
Just put the cursor at the peak of interest. Click "Controls," "Estimate IR Delay." Then "Cancel," of course.
But no one has confirmed that this is the measurement you need.
I thought I posted how to do it. Did you miss that post?
So you are using an SPL as a mic? on a Mac? What happened to using a standard configuration, Brian?
I just tried using the SPL as follows (on a Windows system):
- Connected the SPL RCA output to the laptop microphone input using an RCA-to-2.5 mm mini-jack cable.
- Used the laptop internal speakers as output (just for the test)
- Used the Java driver
- Ran the mic calibration (which worked just fine)
- Ran a test measurement (a simple 500-1000Hz sweep)
This test was successful, so in principle the SPL can be used in lieu of a microphone. However, we know the SPL meter's accuracy is not good, so why use it?
So, what is your question? Don't ask anything associated with a Mac to me, please.
Thanks Nyal. I get it now.
That is one of the things that I always like about your posts - you do not offer a dogmatic "this is the way to do it and nothing else is good enough" approach. Thankfully, in this thread, that approach is rare, but it is prevalent on AVS in general. I prefer something different to you - I like the 'tack sharp images' that I've discovered since treating the room and eliminating most of the reflections that were 'fuzzing it' a bit before. We've discussed this in the past and I have said that with m/ch movies (my only serious listening in my HT) I am of the view that any and all ambiance etc that I need is already hard-wired into the soundtrack by the mixer. Of course, if I used the room for music, and especially classical music, I may well have an entirely different POV. But despite the fact that our preferences are quite different, you were still nonetheless able to give me terrific advice on speaker and sub placement, which increased my enjoyment of the room exponentially.
Incidentally, I find, with my movies, that the walls do more or less 'disappear' here. What I really like is the way the mixer and my room work together to give me the ambiance of the space I see on screen. If it is a small, claustrophobic space, that is what I hear. If it is a vast cavern of a space, that is what hear. If it is the great outdoors, or a city street etc etc, that is what I hear. I never really noticed this, to this extent, before I added the treatments, but the whole effect now adds considerable additional enjoyment to the movie soundtracks. This effect has also increased, psychoacoustically and psychologically since I installed my PJ and the big (for the room) screen that goes with it. The big sound is finally married to the big picture.
Jim, I think your post really gets to the heart of the issue of "picking a model". The part I struggled with most is exactly what you have described above - if I can't hear all of the models then how will I know if I've chosen the right one for me?! It's not like you can just head down a path of implementing an LEDE/RFZ model and once you finally get there in your listening space (nevermind the effort it took just to get there) and then just decide, hmmm maybe an NE or Ambechoic model was really the right choice?! This just doesn't seem practical if you ask me since it's hard enough to achieve any one of the models let alone trying them all on for size and then determining which one you prefer most.
That's why I've settled on the approach I'm taking. In the end, I'm the one that ultimately matters the most wrt how it sounds (since nobody else in my house really cares one way or the other) so I'm going to implement ideas that "make sense" to me but are not so permanent that I can't undo anything that's been done (in theory, nothing is really permanent but I mean in the practical sense regarding time, money and available resources). Hopefully, I'll like the results but obviously, there's no guarantee!
