qirex posted:runner up is this, a bargain at one thousand eight hundred of your earth dollars TBH, that's a pretty cool way to do a clock, and gives me some ideas. But yeah, with an arduino and a couple of repurposed VU meters, it could be done for a few (not thousand) bucks. Oh, wait. That's probably what's inside there, anyway.

I hope this is the right thread, but if not please redirect me. I'm trying to upgrade my home stereo system. Currently what I use is my old Akai AM-U33 amp with my turntable on the phone input and my TV running into an analog converter and then into one of the aux inputs. Sound comes from a pair of old Sonic speaker cabinets that I re-speakered with celestions years ago, and these speakers also serve as small tables for some vintage lamps that are part of our 1960s living room setup. This system, while it has served adequately, is not where I want to be. So, please direct me to a better amp and speakers that can a) handle both turntable and television inputs, b) sound super clear, and c) possibly still serves as small tables for my lamps. I'd also like to keep things to under $1000 all together if possible. Help?

Tiger repelling rocks are an optional accessory. However, some find they reduce the vertically of their music, so they pick up some of our entallener cable lifts to offset this. If you're using uncompensated tiger protection in your current set up, call now and we'll give you a special deal so you can see what you've been missing.

Thanks for the help, the phone call really cleared things up. Love the chance to join the $100k customer club! I think I can feel the tiger effects already, it's like they know the tracking number has been accepted by China Post. Anyway, they have been keeping their distance even though I started the decompression soft landing protocol on the microblimp uavs suspending the old cable through the local wildflower crtyobiome cable terrarium.This will be the best USB cable ever, can't wait to see what the ole Marantz does with this crystal clear signal. I think I have the tuning really optimized now, I mounted the usb-fm transmitter upside down (MegaCrystal organic jute cable hangers, 12mo aged, repurposed for the transmitter with some RF pheremone spray, I've got a guy if you need a hookup) and the blacks really opened up. 5stars, live to see science improving lives! keep up the good work

LRADIKAL posted:What a deal! 10$ a watt, includes tubes and solid state! $5/watt. It's $6k for the pair and each does 600W@8 OHMs or 1200W@4 OHMs, so $2.50/watt if you're running 4ohm speakers. The 12AU7 is just an input buffer I think. The THD specs are decent enough and that's a fuckton of power with a nice feature set. I'd say this is only boarderline Audiofool when you consider that you could spend 3/4 that much on some Pro Audio PA equipment to achieve the end result and it wouldn't look nearly as nice and might not have remote trigger capabilities. It's still in beta though so we'll see what this looks like when it actually drops.

I've just ran into some AI experiment that tries to generate novel audio based on existing songs that you input into the machine learning algorithm, which made me wonder, is there anyone that has tried to do ML based audio codecs? Train an autoencoder to figure out on its own how to compress audio the best?

I think a prerequisite would be to train a network to recognize the same kinds of quality loss humans accept, i.e. a measure of quality of audio compression that's more predictive of human ratings than PSNR and other algorithmic measures.

they're doing it for video, just a matter of time until it's done for audio (if not already)

I predict if an AI was given free reign to design an audio or video codec end-to-end it would eventually become a Turing-complete system where the encoder produces a program that will reproduce the input.

Firstly, it is thought that ferrous ingredients contained in the printing ink of the label side of the disc is one of the causes of magnetizing discs. For example, iron oxide is used for red, yellow or brown ink, cobalt is used for blue or green ink and nickel is used for silver ink. These materials, iron, cobalt, nickel, are called ferromagnetic substances, and they are relatively easy to magnetize. Second, problems are caused by the use of aluminum used for the recording side of CD. Currently, the JIS (Japanese Industrial Standard) states that the purity of the aluminum used must be 99.0%. The other 1% contains ferromagnetic substance such as iron, nickel and cobalt. Aluminum is a weak magnetic material, so it is easily influenced by magnetism. CD players contain magnetic substances, when a disc is played, the rotation of the mechanism, magnet and motor generates a flux which quickly causes discs to become magnetized. The multi-purpose audio demagnetizer RD-3 is a ground breaking appliance which can easily treat and completely demagnetize all kind of optical discs (CD, DVD, etc). If you demagnetize your disc by RD-3, sound and picture quality are much improved and you will be able to hear aspects of the recording that were inaudible from magnetized discs. RD-3 also has a remarkable effect on digital recording media such as CD-R, DVD-R. If a disc is demagnetized by RD-3 before recording, the sound quality improves greatly regardless of the recording device or software. For this reason, the RD-3 is widely used in the mastering rooms of major recording studios.

The only way you'll get even remotely acceptable audio quality out of Bluetooth is to adjust the tonal color balance of the room you're listening in, otherwise everything will be too, well, blue. Smartbulbs produce too much interference so you'll have to hand-phosphor some bulbs (LEDs are far too digital for proper tonal color production). You need an appropriate number of black lights too to ensure you're not brightening your blacks from all the light sources, so invest in some skin protection as well.

One of my favorite audiophile reviewer things is "tightness" or "organization" like one amp will just let some sounds float around in there. What Hi-fi is especially bad at this:quote:The One Cast finds timing a struggle and is less than adept at organising instruments so that their input feels beneficial. At best, it is all a bit messy; at worst, more intricate pieces can sound almost entirely unrehearsed.

It's because they used the wrong model of vacuum tube in the violin circuits of the amp, obviously.

The talk about high frequencies reminds me of this: https://www.youtube.com/watch?v=L34S4Tt1EuQ Whenever I watch this I'm 100% convinced that the reason this headphone probably sounds so agonizing and sibilant is because it's targeted at people with super hearing loss and somehow Tyll got unscathed.
