    Can math solve the question of how many bits of resolution are in use here?

    it's amusing the trouble we go through to get nearly perfect sound. the sad part, out of thousands of recordings that i own there are at most a couple dozen that both have a great performance and are well recorded.

    Send multiple (64) bytes via I2C in a loop?

    The art of war is a young man's book, may i suggest a tang dynasty poem, The Song of Everlasting Regret, should fit in an even smaller eeprom.

    I want to detect the presence of DC while ignoring audio signal AC

    The audiophile business is fascinating class D acceptance boggles the mind but it's nothing new there was a fancy amplifier that used a national semi chip and charged a premium price. I remember when Carver first used a switching power supply and it was accepted who knows if it is now. The part...

    I want to detect the presence of DC while ignoring audio signal AC

    A few decades ago I did buy an audiophile amplifier, back breaking heavy. It's the only amplifier of many I've owned that blew the output stage. Seems like the more expensive an amplifier, the greater the chance of failure. Can't agree more. As much as I listen to my hi fi I also attend many...

    I want to detect the presence of DC while ignoring audio signal AC

    How often do people blow speakers, I have a pair I bought in 1981, played pretty much daily and never even blew a fuse. I'm assuming fuses are no longer audiophile approved, my speakers have a single fuse that goes to a Peerless tweeter. I did replace the fuses as preventative maintenance...

    I had my first go with AI using bing, the results were less than impressive. I'm also seeing it all over the web, I looked up my favorite violinist and was taken to a website that had all the data correct, written badly. Reading anything by hippy, alen and a number of others is more than...

    the debates have happened long ago, post modernism is very old. people cranking out much of this drivel are poorly educated computer nerds serving drivel to poorly educated public. there was a time when engineers and scientists received a well rounded education, J. Robert Oppenheimer was a...

    Generating code with ChatGPT

    I think AI will be little more than a novelty, tech is hitting a wall and they are trying anything and everything to stay relevant. I have a 10 year old laptop and a brand new one, for everything I use a laptop there is no difference, yes the 10 year old laptop was a higher end unit at the time...
