BFD just got easier.
I haven't tried it yet. Will the first person who does report back?

Have fun,

Cool, I'll be checking it out as soon as I can.

Funny, I just posted that link not 5 min. ago in the "My BFD Experience" thread. I'll definitely be giving this app a spin once I get everything set up. Just hoping my soundcard will be up to snuff...
-
I will give it a try at the end of next week when I have time for more measuring.

Testing it now. It's doing a painfully slow 20-200Hz sweep. So far it seems pretty good and includes a lookback function like ETF. Unfortunately, my native notebook soundcard only has a mic in and not a stereo line in. I'm testing with my external card and mic right now. Will report back graph comparison to my previous findings.

I'm done playing for this evening. It seems to work as advertised, but the 20-200Hz sweeps went in 1Hz increments and took 10min!! Talk about a painfully slow sweep.
The resulting graph looks very similar to my ETF one, except the 20-40Hz hump was disproportionally high. Both the RS meter and my ETF measurements (with the same equipment) showed those to peak around 20db above normal whereas this app showed them with a 30db peak. This confuses me since the rest of the measurements seemed to be on track.
My battery is dead and I'm going to chill for the rest of the night, so that's it for now. This definitely has a lot of potential.

Brad,
Can you clarify for me how you are sending the signal from your soundcard to your AVR/pre-amp? Are you simply connecting to the analog LFE (.1) input, or is your AVR/pre-amp capable of routing incoming signals to different speakers?
The reason I ask is that I am hoping to test my response: 1) before any changes, 2)with BFD filters in place, and 3)after the HK performs its EQ.
If I have to use the LFE analog input, I won't be able to test #3 (at least not with Room EQ Wizard) because the 635 will not do EQ on the 7.1 analog inputs, and I'm uncleear how to route an incoming signal (on say, the "CD" input) to just the sub.
Hope that made sense...
-
I am just sending the input into the right channel of one of the analog inputs (specifically the one on the front panel). The AVR does its bass management (I have it set for an 80Hz crossover), but it does not have any EQ capabilities.
-
Ok, thanks. Maybe I'm just overthinking things (as usual), but I'm getting hung up on the following in the Room EQ Wizard's config requirements:
"The input used on your AV processor must be one that the processor can route to any speaker output....If the processor does not have such a signal routing facility it may have 5.1 or 7.1 analog inputs that can be used."
Does the software control the routing (i.e. send a standard analog signal to the sub only), or must the AVR have this ability?
-
The software can't control the AVR at all. I don't know anything about the EQ function on your AVR, but the tests I did don't require any special 'routing' capabilities. I just set the receiver to have the sub as being 'on' with a crossover of 80Hz. It then sends signals below 80Hz (really above that too, depending ont he crossover slope) to the sub instead of the main speakers.
