$2k bounty for anyone who can help decode Opus stream

Posted by GianIsAlive on Tuesday December 12, 2023 @06:57PM
from the self-post dept.

The company I'm helping is using a Chinese manufacturer for their wireless microphone. They said it's "8:1 opus compression" but after reading all the documentation, I had no idea what it means. However, I know what the end audio sound like, I can even get mp3 and pcm format, but it's from a third party app. I'm look for someone to zoom or google meet, and you work with me to figure out a way...

Ask HN: Need some help to deal with power line noise

Posted by GianIsAlive on Monday May 01, 2023 @02:35PM
from the ask-hn dept.

Hi y'all, I'm relatively new to EE. I used to make project in NYC where power lines are buried underground, but ever since I move to Portland, I've been having tons of trouble with power line noise. Both high voltage and low voltage are are really are right outside of my home office. They are significant enough to:1. Unable to calibrate my Keysight scope 2. Peripherals started syncing with 60...

The post sounds a bit emotionally charged... I've met people who can code and optimize SGD from scratch, but never wrote linked list more than once or twice in their life. I've also met people who are so proud of their algorithm and data structure knowledge, they tried to use it everywhere, like connecting instances in a linked list, which killed efficiency. If anyone self taught is reading this, don't be discouraged, keep learning and you'll get there, some of the best developers I know were self taught.

Interesting. I like the aesthetic. Personally I'm not good at reading shorthand and lambda functions in python. I rather type it out fully to help with clarity. But the simplicity is intriguing. I can totally see people find joy program in it :)

Sorry it didn't hit the mark for you. It's my attempt to explain it with geometry, but I clearly need to improve my writing.

Thank you for sharing!

This is a way better explaination. Thank you! I do agree my writing could be better.

I wouldn't say over sampling is wrong. Inefficiency and inaccuracy has different consequences in my opinion. Maybe I'm missing something idk.

Thank you. I read a lot of papers drive equations from Euler's formula, which helped with result, but I didn't have any intuitive understanding, but when I watched geometric breakdown of it, it suddenly made sense. It's just my attempt to share my excitement. I do agree my writing could definitely be improved.

I like his video too! Thanks for sharing.
Re:How does anyone learn anything? on Monday April 24, 2023 @06:50PM (#35694319)
What do you want to learn? Try top down approach. Meaning if you want to build electronics, start broad, get Arduino, run sample code, get it to do things, then dive into details only if it's necessary. In my opinion, it's useless to memorize bunch of equations, it doesn't come up as often as you think, and eventually you'll forget about them. Don't get discouraged, feel free to email me for more tips. I also write about my learning process in case it helps anyone: https://sayingless.substack.com
Re:Ask HN: Any advice for someone looking to buy an existing business? on Monday April 24, 2023 @03:28PM (#35692027)
I imagine the process is like any acquisition. From what I've seen so far, basic things people look for: 1. Business Registration (LLC, B corp, C corp, etc) 2. PnL for past 5 years 3. Tax statements 4. Banking statements 5. Inspect codebase, database, and cloud infra.

Also I'm surprised that you'd ask it here. Considering you're about to drop $250k, I imagine you'd hire a lawyer to look over everything.
