Seriously, stop being an asshole. Coil whine is a well-documented behaviour that creates a loud, high pitched noise.
As coil whine is at the very limit of what human hearing can accomplish, it doesn’t take much until you’re unable to hear it. So you’re likely too old or went to too many concerts to be able to hear it.
Good ears? the question is when, not where, and the answer is half a lifetime ago.
Considering that reading source code can take a long time
You’ll get faster over time, until reading code is faster than reading documentation, as code will always represent what’s truly happening, while docs are frequently outdated.
In a language the user isn’t familiar with
If you’re not that familiar with the language, it’s likely you won’t be contributing to the project. Open source projects usually to have quite limited resources, so they tend to optimize docs and dev UX for people who are likely to contribute.
Sure, it’d be a solution for five minutes until someone delids the secure enclave on the gaming card, extracts the keys, and builds their own open source hw alternative.
High-performance FPGAs are actually relatively cheap if you take apart broken elgato/bmd capture cards, just a pain in the butt to reball and solder them. But possibly the cheapest way to be able to emulate any chip you could want.
Even half an hour next to the PA without special ear plugs is enough to permanently harm your hearing.
