I've recently been learning about superhet and frequency mixing and wanted to start tinkering. Specifically I'd like to try using two heterodynes in series to first frequency shift then uninvert the original audio, sort of like an analog frequency shifter.

To do this, I'd need a frequency mixer. I've been looking at a ring modulator (like https://upload.wikimedia.org/wikipedia/commons/1/1b/Diode_DBM.png) which should require 4 shottky diodes and 2 center-tapped transformers. I've had difficulty locating an affordable transformer, with good enough fidelity for audio, that also includes a center tap.

I have a few questions:

• Where can I locate affordable, good-enough-for-audio transformers?
• Is the ring mod approach good enough? I see there's also a gilbert cell.
• Any general advice for someone just starting a project like this?

Thanks!

Hi everyone,

I have put together a simple python script to automatically transcode all your favorited music on Jellyfin to a directory, for use with, for example, Syncthing. This has made it dead simple to manage the subset of my music library I keep downloaded on my phone: simply favorite to add, unfavorite to remove.

I'm hoping that someone out there finds it useful. Let me know if you have any questions.

Hi everybody,

I'm a mostly self-taught musician who mainly plays acoustic guitar. I've recently been learning certain versions of jazz standards for fun, girl from ipanema, autumn leaves, and I've been trying to pick up a few others, but I feel like I'm hitting a brick wall. I'm having trouble upgrading from mimicry to a more holistic understanding of the pieces. For example, if I were to play with someone else in another key, I'd have to fumble around a bit to transpose it mentally. I guess that may be caused by me learning only specific versions. Some questions:

• Does anyone have tips for learning standards?
• How can I locate the "purest" form of a standard, if that even makes sense? I feel like learning certain interpretations with their own flair isn't ideal.

Hi everyone,

I've got quite a long drive coming up and was interested in finding some audiobooks, which got me thinking, has anyone listened to (also, do they exist) any programming-centric audiobooks recently?

I figure podcasts might be the more popular format for technical content, but I'd be more interested in an audiobook if people know of any good ones.

I'm primarily a python developer if that helps narrow it down. Interested in LLMs, python core stuff, message brokers, databases, whatever!

Let me know if you have any leads!

Let me know what you think!

I enjoy making and sharing things, like websites, music, art, whatever. Is there a good lemmy community for this? It can be media-specific or not, but I've browsed all communities for a while and nothing has popped up at me.
