Basically, the title. After years of inactivty, I'll be taking music (cello) lessons again, with my teacher of yesteryear, from whom I've moved half a country away.

She has suggested Zoom but is open to alternatives. I don't particularly like Zoom, plus I have a feeling better quality can be had through a custom solution - but I'm at a bit of a loss as to what exactly would be a good fit for this project.

Maybe Jitsi? Does someone here have experience with it and could tell me if it's possible to set something like a "target" audio quality?

For hardware, I basically have two options. Both are already in use, for different things, and have sufficient processing capabilities - albeit no GPU:

• host everything at home. Plus: lowest possible latency from me to the server. Not sure how much that is worth though.
• root server in the Hetzner cloud: much faster network speed. Again though, not sure how beneficial that is, the ultimate bottleneck will always be my upload speed (40Mbit)

OK, I realize that this post is a but of a random assortment of thoughts. I'd be really happy about suggestions and / or hearing about other's experiences with similar use-cases!
