I have this weird thing whenever I have headphones and open the Dota2 settings on my Mac, then I not only get buzzing but the overall sound quality plummets!

> 100-1000x lower than any transducer This seems like a lot but it's only 20-30db lower than whatever reference they're using. This is the spec that really matters: THD+N: 0.0003% which is roughly -110 dB. It's very good and completely inaudible but not exceptional these days.
THD+N is irrelevant for the issue the author is describing, through. You need to spec PSRR (power supply rejection ratio). Many individual ICs do not spec this, and pretty much every system does not spec this.
The buzz isn't completely gone but now I can't hear it unless I'm paying attention to it, which if I am playing beat saber, I'm not.
> A picking texture is a very simple idea. As the name says, it’s used to handle picking in the game, when you click somewhere on the screen (e.g. to select an unit), I use this texture to know what you clicked on. Instead of colors, every object instance writes their EntityID to this texture. Then, when you click the mouse, you check what id is in the pixel under the mouse position. Unrelated, but why? Querying a po…

No need for UPS, a good external usb soundcard with power supply will solve that problem. I have all connected to the the same power circuit and with a Elektron Digitakt as audio device and have zero noise. With audio devices powered by USB there is a lot of noise.
Sigh , it's almost like I had this conversation before. My audio equipment is not connected by USB. It's connected by optical (TOSLINK) to an external DAC. TOSLINK is not great, but it shows that it is not a USB noise problem.
I remember 15+ years ago reading about certain laptops (Dell?) that you could 'hear' scrolling on websites, somehow the video chip was interfering with the sound chips. I had one at the time it was pretty weird.
Just ordered a hat for my Raspberry Pi with optical out, with a plan to make that my main music streamer. Excited to see if that works out!

If you had that conversation before and you still having noise, maybe you are not doing the right thing... Sigh...

What’s with the animosity towards Schiit? They seem to make decent products. Noise from using USB power delivery for audio devices is common.. that’s why you can (and should) use the dedicated power input to you DAC/amp
>They seem to make decent products I don't agree with that sentiment. Their designs are subpar and the quality of the soldering is (maybe was) unacceptable: https://www.audiosciencereview.com/forum/index.php?threads/h... https://www.audiosciencereview.com/forum/index.php?threads/b... The above review specifically goes into the problem from OP. There's also their amplifier with a rather non-standard architecture that…

> No doubt you have noticed my frequent use of terms "nice" and "excellent" and that sums up the performance of Modi+. At this price point, we don't expect objective perfection but competent engineering and that is what we have. Physically, the unit is solidly built and of course supported by an English speaking US company. For people with such preference, the Modi+ provides an excellent option. That they can stay competitive with far east audio companies is definitely a feather in their cap.
> I am going to recommend the Schiit Modi+ DAC. Great to see Schiit continue the (new) tradition of optimizing objective performance as they cater to their traditional audience.

Moving my cursor makes an audible sound over my (builtin) audio card. I always blamed inductors somewhere (noisy power). This has never not been the case with any desktop with built-in audio I have owned over the past 25+ years
