I have a power conditioner in my amp rack for my PA stuff. I bought it because it's a cheapish IEC multi-out. It makes everything sound WONDERFUL

Yeah run 240v to your recording space and plug in a bunch of server UPS'. TrippLite makes alright ones but APC is fantastic. Also make sure you have a proper ground bus bar and tie that into the UPS. Provided everything plugs straight into the UPS', you will never have to worry about ground loop. Just make sure no signal wires run in parallel with your mains.

You already got good answers, but it somewhat depends on how much stuff you need to plug in and what's causing you the most grief. I have only a handful of things because I use a Line 6 Helix these days and Roland drums so there's not a lot to deal with. If you have racks of stuff, you'll need to do the larger stuff mentioned by others. This is also probably the wrong thread for it, and I'd guess there's a "right" thread somewhere in Musician's Lounge where you'll get way better answers. Here someone's going to tell you that your problem is that you don't have any crystals and I'd bet money that none of your volume knobs are wooden.

Burn all your gear and start from scratch. I'd start with a crystal radio kit to get your skills up before you actually try to listen to anything. In the meantime, consider using earplugs to limit your exposure to rough soundwaves that can snag and get hung up in your ear canals.

I found this gem with various arguments online about listening to cables and if a high end analog cable makes a difference or not and stranded vs solid core and cables spending years in development. This was while trying to find an instrument cable that looks weird because I'd be more interested in weird over sensible. Now while these are expensive instrument cables at a couple hundred USD per at retailers and solid core, that isn't the worst. Apparently even high end XLR cables can have enough variation from cable to cable that they sell them in matched pairs. I could be very behind in cable science but I'd imagine two XLR cables of the same length and same cable and ends would be effectively identical but apparently there is such variation that they need to be matched together. How long until someone makes matched pair power cords for active speakers or monoblock amplifiers? I can't imagine trying to use a solid core cable for a musical instrument if that actually means a solid core and not that someone else makes one of those liquid filled speaker cables but for instruments. It seems like a recipe for a broken wire or the cable just being far too stiff. In the search I even ended up reading gearslutz arguments over that cable brand and how it opens up the soundscape etc etc and do cables even matter. I think that qualified as some sort of self flagellation.

A lot of the measurements they use are things that are way outside the realm of audible sound, but they don't let that stop them from saying things like "capacitance at 2.385GHz was reduced dramatically when we did X", and then claiming it had a huge effect on "soundstage", and "deep blacks", and "instrumental differentiation".

They're getting down to mass market prices, now's the time to make good margin before they become a commodity.

They are already commodity mass market items, the only way to make money on them is either niche (audio quality, integration with devices) or branding. You can get perfectly good Bluetooth iems direct from the manufacture in China for £20 and a six week wait. Unless you are already an established manufacturer with lots of interesting patents to throw into the device like Sony or Bose then you need the Youtube shills to pump your product. Hell, if you were going to buy a few tens of thousand units you can get your own brand designed and made by the same OEM manufactures that the likes of Raycon use.

I got a Marantz CD-46 for $15 and I was googling the DAC to find a bunch of audiophiles talking about oversampling being bad and stair steps in the audio signal etc etc. Anyway what is the normal-person consensus on oversampling CD players? Apparently it's DAC doesn't oversample which is why the nuts are drawn to it, which immediately makes me think that oversampling is good and cool.

As near as I know, no one has ever been able to differentiate between DACs in a properly conducted double blind test. So the normal person consensus is who cares? Buy what looks cool, makes you happy, and you can easily afford. I think that Marantz probably fits all 3.

Apparently it's DAC doesn't oversample which is why the nuts are drawn to it, which immediately makes me think that oversampling is good and cool. Ignore the audiophiles, in an oversampling DAC the oversampling is a vital part of how it removes the stairstepping from its output. Also the CD-46 apparently uses the Philips TDA1545 DAC IC. I looked up its datasheet and it's an old and quite odd DAC design, which is probably why it's catnip for audiophiles. I don't think you can support the idea that it's not oversampled because its datasheet mentions using it in oversampled applications. (Like many DACs from its era, it's a building block rather than a completed DAC in one chip - it needs external support. So if you wanted to build a complete oversampling DAC circuit with the TDA1545, you could.) Oversampling is indeed good and cool, one of the valid techniques for implementing the sampling theory behind digital audio reproduction.

I think that a 44khz output doesn't have stair-stepping at all due to application of the Nyquist Theorem.

Buy what looks cool, makes you happy, and you can easily afford. This is the 'Ridicule Audiophiles' thread so I am throwing myself on the pyre here but this deserves a bit of qualification. The bits and bytes part of a DAC isn't what you hear, the AC part is. There are some dacs that do a real poo poo job of both though. I've had a couple DACs that couldn't decode their way our of a wet paper bag and CD players with terrible op-amp implementations that needed a unity gain buffer in order to drive a class D amp. That's more of a fault of the amp, but it wouldn't be a problem with an appropriate output impedance. That all being said that cd player is probably fine enough that it's sound quality isn't going to be it's biggest drawback.

^^^^^^^E: it's perfectly possible to make a lovely DAC.LRADIKAL posted:I think that a 44khz output doesn't have stair-stepping at all due to application of the Nyquist Theorem. It's this. The stair steps are an inaccuracy in graphics. The the samples are single points, a DAC creates the sum of sine waves through them. Per Nyquist this is a perfect reconstruction of the original signal, subject to a couple trivially achieved conditions. Physically limitations on ADCs and DACs create a small amount of quantization noise, but nothing audible.

What's the point of sampling above 44.1/48khz? Just snake oil?
|
# ? Jun 9, 2020 21:38 |

Afaik it allows you to do more digital signal processing with less noise (a higher sample rate effectively drops the noise floor)
|
# ? Jun 9, 2020 21:45 |

Also, if you are going to do audio production of the recorded track, especially pitch shifting or speed shifting.

I really wish more people would use lollipop charts instead of bar charts for sampling. Helps drive the point home that the reproduced wave isn't a jagged line following some stupid rear end chart visualization, but intersects a lot of points instead

Really, any manipulation of the sound including digital effects. Some Goon posted:In production it gives you more room to mess with the signal before mixing down to distribution quality. In playback it's snake oil. Depends on what you consider playback I suppose... My MiniDSP 2x4HD is worlds better at room correction when using a 96khz sample rate vs 44.1 But that's correcting for 4 lovely speakers in a small and well treated room. I haven't had the opportunity to set it up to be the active crossover for just 2 speakers yet so I can't really speak to if that matters with regards to sample rate, but I highly doubt it.

GnarlyCharlie4u posted:Depends on what you consider playback I suppose... I would say "signal processing" rather than "production", really. 96kHz sample rate gives more than enough headroom to minimize artifacts from filters, similar to how 24 bit depth assures that you really don't have to worry about the noise floor creeping up into the audible range while messing with the signal, unless you really mess up bad. It's the "don't worry about it" setting. If you do signal processing at 44.1kHz and 16 bits, you have to know what you're doing to not mess it up. For the final end result signal being output by the last DAC in the chain, yeah just use 44.1 or 48kHz at 16 bits, job done. E: In fact, unless you have to use 44.1kHz for whatever reasons of compatibility if/when you distribute audio to customers, just use 48kHz, please just let us standardize for once. It's the default sample rate on phones and stuff, you would be making life so much easier. KozmoNaut fucked around with this message at 16:21 on Jun 10, 2020 |
