Pretty cool! But it’s misnamed; it’s not actually a graphic equalizer, it’s actually more of an audio spectrum analyzer.

[@johnwest7993]

From chips to code generation, technology grows stranger and stranger. The brave, new world is upon us.

[@KJ6EAD]

I've known of this forever. It's better than a bag of filters for displaying low resolution audio spectra. Since it's mainly for making a cool looking display, the filters need to have lowish Q so there's no gap between bands in use.

[@Retinatronics]

This is really cool. I hope it will be fast enough if I make audio spectrum analyzer for my amplifier.

[@AnalogDude_]

So you need to connect the DC out to a ADC pin of the MCU? ...and the reset pin indicates when to start measuring?

[@kpnconsulting8739]

The three days work was worth it just to see all the frothing and fulminating in the comments (wink). Also, that company has a few other interesting single chip signal processors. Maybe you've just got to be an OG to appreciate these things...

[@BaldurNorddahl]

seems a bit outdated. You can just use an adc pin and run the FIR filter on the mcu.

[@gorak9000]

That'd take a lot of CPU cycles on the mcu though, this eliminates all of the fft math

[@robinbrowne5419]

That's pretty cool. It could dance to the music 🎶.

[@ericpilboue3276]

Very cool IC, i never understood aop+R+C = filters + headache 😂😂😂 I Like this circuit i need bandpass filter on each 50 hz harmonics

[@Peter-W1]

i used one of these chips a copule of years ago to tweak a disco light 4 lamps to sort out BAS , MEDIUM low , MEDIUM high and HIGH it worked mush better than the cheap analog filters that was the original.

[@byronwatkins2565]

It has a very slow response... You COULD use synchronous logic and ADC or comparators+totem pole to implement a graphic analyzer, but a microcontroller is much simpler and cheaper.

[@gorak9000]

To be honest, did chatGPT "write" the code? Or did it actually just steal and regurgitate someone else's code that was posted online somewhere (most likely on github), and charged you for the service of stealing it??

[@BaldurNorddahl]

ChatGPT writes its own code. It even has a filter now that checks that the generated code is not too similar to anything else out there.

[@farzadb82]

Let me flip your question around... When you write code to prototype something quickly do you sit down and analyze the datasheets and write your own "original" code from scratch or do you Google for someone's example on stack overflow, or equivalent site and use that in part or in whole for your use case?

[@qwaqwa1960]

Graphics Equalizer? Like, Photoshop?

6:42 beats like 99% of e.g. modern EEVBlog YT..

AI's great. Soon we'll stay home and watch IMSAIGUY videos all day long and let AI do our jobs; sign me up !!

[@jimomertz]

I don’t think IMSAIGuy exists. All these videos are AI generated. 😱

[@andymouse]

Nice ! thanks for the code...cheers.

[@jessen00001]

Nice stuff❤ thank u so much

[@KeritechElectronics]

Pretty interesting to see an AI written code that actually works. @EEVBlog didn't pull that off, but it was months ago.

[@frankowalker4662]

Neat.

[@TheStuffMade]

Why bother when you can get very cheap proper DSP chips these days?

[@RobsonWilliam82]

Just let the people play and learn. 😉

[@TheStuffMade]

@@RobsonWilliam82 Let's waste people's time on outdates tech.. why?

[@cocusar]

this is an old chip, from 2004. I think running proper fft wasn't economically viable back then. and as to why show it now, it's because he shows a bunch of random chips and tests them, old and new.

[@PlaceholderforBjorn]

For the fun of it?

[@andymouse]

@@TheStuffMade Miserable sod. No body's time is being wasted as this stuff aint mandatory sunshine.
