  • Everything about the exact timbre of your voice is captured in the waveform that represents it. To the extent that the sampling rate and bit depth are good enough to mimic your actual voice without introducing digital artefacts (something analogous to a pixelated image) that’s all it takes to reproduce any sound with arbitrary precision.

    Timbre is the result of having a specific set of frequencies playing simultaneously, that is characteristic of the specific shape and material properties of the object vibrating (be it a guitar string, drum skin, or vocal chords).

    As for how multiple frequencies can “exist” simultaneously at a single instant in time, you might want to read up on Fourier’s theorem and watch 3Blue1Brown’s brilliant series on differential equations that explores Fourier series https://www.youtube.com/watch?v=spUNpyF58BY

    I have used Ubuntu as the daily driver for the last 10 years, because support and tools are widespread and easy, and I don’t need any extra pain in my life. Drivers are mostly present and working upon a clean install, and in the one case where the touchpad wasn’t recognized, it was super easy to find an ubuntu forum post containing a 1-line command to fix it. But everybody says i should hate it and use Mint instead.

    I’m open to give it a go, but in general, will most of the tutorials and fixes you find for Ubuntu also work with Mint?








  • I have a Quest 2 VR headset that I use for playing sim racing like Assetto Corsa, and flight sim on Xplane 11. To use that I have to open up Meta’s Quest app, connect the headset to the computer over the WIFI, and it sorta functions like a monitor. In that I can view the whole Windows desktop environment on a virtual screen floating in VR space. When you open a VR game like Xplane you stop seeing the floating monitor, and it takes over the whole VR eye space for the duration you play it.

    Is this type of thing also possible on Ubuntu? If so, I’ll shitcan Windows ASAP.


  • As an Ubuntu + Win10 dual booter I had a couple of instances where Windows update destroyed things so irreparably that live Ubuntu boot-repair failed to work, and hours of back-and-forthing error messages to Ubuntu IRC and discord support channels yielded nothing. And I’m too stupid to know any other way of fixing it, so I was SOL. Your milage may vary.
