    cotton absorbers

    I am just wondering if there's anyone out there besides me that uses Bonded Logic's recycled blue jean cotton for sound absorption. I used this in the construction of my studio walls but after seeing the absorption coefficient on bobgolds.com, I had to try it later on the walls. I don't have...

    best fabric for diy acoustic panels an basstraps with images

    I am not an expert but I have a few thoughts on the matter. If you have samples of the cloths, hold each over a speaker (while it's playing of course) and see which one is more acoustically transparent. Regarding mounting with magnets, sounds like a maybe but you can always try it. 72 lbs of...

    Cannot get good data for card calibration

    Back in business! Thanks to my friend, Steve Allen. Turns out it was a clock syncing issue. MY FAULT. My PCIe card that talks to my ASIO drivers as well as my ADDA converter was using its own clock instead of syncing to my converter. Once we made the converter the slave, everything matched...

    Cannot get good data for card calibration

    Thanks, ddude. Thanks for checking out the sweep on other tools. The blip that shows in the REW frequency report is semi-repeatable. It repeats in that there is always a blip. However, it appears at different frequencies, anywhere from 200-14000 Hz depending on the volume of input. As of an...

    Cannot get good data for card calibration

    Unfortunately I cannot because I do not have a battery. It's a desktop computer. (Yeah, I'm one of those people.) Thanks for your thoughtfulness. This is a great forum. I think I'll give it a rest for a few days. :)

    Cannot get good data for card calibration

    Thank you, sm52 and Bernard. Sorry for the late response, I didn't realize someone had answered. I'm using a desktop. In fact, two desktops. Swapping out the power supplies does have a significant hassle factor... or did you mean just use the battery? I've taken some time off because this and...

    Cannot get good data for card calibration

    As suggested by Mr. Mulachy, I tried sweeping REW measurements with and without the WiFi turned on. Both have the blip... but at different places. Nothing else was changed. Same connection. Same sweep. Same T-shirt I wore yesterday. If anyone can explain The Blip I would be most grateful...

    Cannot get good data for card calibration

    Had a chance to run a slower sweep. Played it back on a different computer using Microsoft Groove Music app. I can't really hear anything unusual. Below is a link to it (11M wav file). https://1drv.ms/u/s!AiLEJtzPzRRQh5kfUIH9VGBiyGEHgw?e=bbabt8 I haven't had a chance yet to turn off the...

    Howdy from California - another Left Coaster

    haha! That's a very kind way to say it. I didn't bother to try and tidy up before I took a picture. That's the mess I usually work in. The live room stays clean for tracking while the control room is just 2 degrees below chaos - but actually manageable.

    Howdy from California - another Left Coaster

    Good eye, ddude. That's a C3 and a Leslie 145. Both are in okay condition but not best in class. I do love the Hammond sound! If I ever open up for business again I'll buy a digital Hammond. Out of the four Hammond techs that I know of around here, three have died in the last three years...

    Cannot get good data for card calibration

    Sorry about the description. The Aurora16 is a stand-alone, rackmount 16-channel AD, 16-channel DA converter. In order for my DAW computer to use it I have a Lynx AES16e (PCIe) sound card that accepts all 16 in and out digital signals. Using ASIO drivers I arbitrarily chose Channel 6 as the...

    Howdy from California - another Left Coaster

    Hey folks - one of 40,000,000 people in California here. I grew up and still live in the San Francisco Bay Area. I've been doing audio on and off for 40 years. I'm an amateur engineer and I have a project studio (photos below). I hope to measure my two rooms in order to improve their...

    Cannot get good data for card calibration

    The sweep is audible; sounds smooth. I do not hear any audible blip and it sweeps through. To be fair; it would be difficult to hear a 2 db change in a relatively fast sweep.
