Find the cat poo poo's resonant frequency

This reminds me of the guy I work with who's got a serval, and the cat apparently got bored and decided he loved the sound of his own voice.

So he found a corner that sounded particularly nice, and would howl into it for hours at a time.

Coworker stuffed the corner with sound treatment foam panels, so the cat went from wall to wall until he found another good echo spot, and went back to howling at himself.

Now, every corner in his house is full of foam, and he's built a whole outdoor enclosure for the cat to play in so he's less bored.

I should ask him if all the foam dampers have improved the overall acoustics of his house...

Servals are super hard to keep entertained. They're too smart to be pets.

Yeah, the outdoor enclosure ended up being what kept his serval from going insane, but dude's got property and resources for that sort of thing.

God drat! That is a lot of caps.
That all reads like a bunch of audiophile mumbo jumbo but the fact of the matter is that he's not particularly incorrect.
Capacitors in the signal path affect sound. That's why they're part of passive speaker crossovers.

Different capacitors affect sound differently, but that's mostly attributable to the caps values or type of cap.

I'm just happy to know that some dork with far too much spare time in their relatively short life reviewed the caps I have in my speakers well (Jensen, if you're wondering).

Bluetooth LC3 is the poo poo, tried it at CES

Just searched google for what to fill speaker stands with and thereís some funny stuff about resonances with different fill material. Apparently, if you put a stethoscope up to the speaker stand you can measure for resonances or some such poo poo.

Stuff like this is fun because it takes something totally reasonable (weíre really sensitive to resonances and should try to minimize them) and turns it into a weird voodoo thing.

Like it would actually be neat to see accelerometer data from different fill material, as well as legit blind testing to see if it made any real world difference. But he people arguing about these things online tend not to be interested in actual research and answers.

Itís one of those where the original idea is good - ďall those little things that resonate add up and increase the background noise floor of the environment, so hey why not dampen the obvious ones?Ē - and goes off on a tangent about the best fill materials, densities, placement etc until it all seems so much effort nobody bothers.

I guarantee you that throwing a thousand bucks some 300mm deep blocks of Rockwool RWA45 stapled into some basic cheap wooden frames and wrapped with an acoustically transparent material, some offcuts of wood chopped at various angles and mounted onto a board, and filling holes and cavities with your generic cheap builderís sand will do a fuckload more for your sound quality than spending magnitudes more on components.

Itís even harder to convince venues and places of work about this. The amount of places I come across in my day job that have spent a fortune on a new speaker system when all they needed was to just treat the drat room and position/tune the existing speakers properly is insane.

Luckily Iím able to - more often than not - do simulations and measurements that convince them otherwise, but there are plenty of nice live music venues, bars, restaurants and even cinemas that I actively avoid because the venue itself is just awful regardless of how good the kit installed is.

New mandatory codec that works on both low-energy and normal versions of Bluetooth, basically a scalable codec like AAC on steroids. But as it's a part of the BT 5.2 core spec it has other goodies baked in.

For example, connecting to multiple headsets at a time, or making true wireless earbuds not suck intense amounts of rear end like they do now. Also, they demoed an emitter for televisions/public spaces that allow people with hearing aids to toggle audio streams and connect directly to the source they're listening to.

Also, because it uses less energy, both hearing aids and earbuds will last longer

Yup, this is what a lot of people fail to realise when thinking about audio which is nuts. I did some work for a family that had spent thousands on a speaker install for their kitchen. A kitchen which was pretty huge, open plan into the rest of the house and completely covered floor to high ceiling with shiny tiling. They were wondering why the expensive speakers they'd bought didn't sound as good as they did in the listening room at the place they bought them from.

That people fail to realise about the listening environment is crazy to me. You can spend tens of thousands on kit but if your listening space is fundamentally bad, you've wasted your money.

As a mild aside is your work place related to your name here at all? A friend knows a dude at Neuron Pro Audio here in the UK and I've been following them because they actually know what they're doing when it comes to sound and setting up venues.

Haha, yeah thatís my company. I donít post here much, considering Iíve been a user under this or other accounts since the early 2000s. So much for anonymity! But thanks, itís nice to see some appreciation because as you say, itís a nightmare uphill battle a lot of the time.

Weíve been far from perfect in the past of course, but actually learning from mistakes and doing research instead of blindly following what everyone does seems to be paying off.

You can talk audio with some relatively intelligent people, and they will outright reject spending any money on room treatment. Rooms where a single hand clap rings for seconds.

If you have a brick and mortar store then they should allow a demo in your premises, via their / your countryís returns policy.

At the very least go do side by side at the store with tracks of your own and those you know.

Ah, now that I think about it I may have asked that same question before! I threw together a Bill Fitzmaurice setup years ago and like you say, it's a learning curve to figure out what works best theoretically and how to alter that when those are indeed theoreticals. There's not much like getting something dialled in properly though.

oh poo poo wait I hope I'm not too late!
I bought a bunch of used QSC power amps, a minidsp HD + mic and I gotta say it's a fantastic setup.
Yeah there's much nicer and expensive ways to do it, but for the money it's a great setup, and I can easily swap passive speakers If I want to re-arrange my space.

Edit: I should specify that I'm using the minidsp as the DSP and active crossover for a pair of 2 way speakers.
