Hi I am importing some measurement sweeps from a digital mic, so in dBFS. I want to use a measurement from a reference mic to correct these by removing the frequency irregularities of the stimulus speaker measured @ the test mic location. In SPL measurements I can offset the reference mic...

Good to see Bass Hunters back! Look forward to future episodes. Question: when you show SPL I assume you are playing back ar Reference Level?

It is a system for a friend. Source would be TV settop box. Just shopping for TV and soundbar, so not firmed up yet. Probably Sony TV. Not sure of HDMI/audio flow - depends on soundbar selected, I think. Could be via HDMI eARC, Toslink, or soundbar HDMI pass through. Which options would work...

I want to extract centre channel to pass to a hearing aids transmitter, then pass the HDMI on to a soundbar & TV. Will that work? Thanks.

This looks very interesting! I have a particular use in mind, and wondered if this device strips out the audio, or does it also pass it along on the HDMI output?

I'm using 4 12" DIY sealed subs in my HT setup. They are located in the corners of my 15x19' room, and driven by 2 stereo B&O IcePower 500 modules. Alignment and tuning via MiniDSP 2x4 balanced, with parameters derived using REW and MSO. I use a house curve flat to about 100 Hz then rising to +6...

You have lized your whole life with the shape of your ear, and your brain has adapted to localize sounds with what are called Pinna (ear) Cues. Anything that messes with this is going to subtract, not add to your audio capabilities. Sounds like total snake oil to me.

Yes, upgraded from a Denon 4700 to a 6700 so I could have front wides...now 9.4.4 setup. It is an improvement in immersion, but only on some source material that has s lot of ambient or surround effects.

I have a Roon lifetime subscription and stream Tidal and Qobuz. I had meant to migrate from Tidal to Qobuz to save money, but have procrastinated due to hassle of migrating favorites....and have less incentive now that Tidal has dropped prices. One day...

Being technical snd somewhat obsessive, I base my cleaning regimen on the expansive document Precision Aqueous Cleaning of Vinyl Records. It covers vacuum and ultrasonic cleaning, focusing on safety (some solutions recommended on the internet are highly flammable), efficacy, and lack of damage...

Wonder how the black levels and contrast will compare to JVC?

The low frequency peaks and dips are most likely room modes, which are nearly impossible to treat with absorption...other than tuned absorbers. Multi Sub layouts can mitigate this, especially if individually tuned using minidsp/MSO or Dirac ARC or similar multisub optimization approaches.

OK, I think I figured it out. I didn't realize that the generator still had to be running to generate the template...so it was set to the wrong frequency.

Thanks John, makes sense. I have another question. In the attached measurement, which has quite high distortion, the overlay does not appear to be lined up with the fundamental. How can I correct this? Thanks

Hi, I am sure there is a simple explanation, but I am trying to figure out why the CEA2010 peak value reported is so much higher than the RTA spectrum value at the peak. See attached chart. Based on the input levels, I actually would expect that the acoustic peak level would be around that...
