torvalds/ AudioNoise

@hoangdesu, I might be too much of a lay man to get this; apologies for ruining it. Can anyone explain?

Turning point

Linus wrote the commit or Antigravity?

If it works don't touch 👀

What a legendary commit message! @torvalds

It isn't my favorite.

wait what ...........Linus bro ??????????

crazyyy

Had to subscribe here... 🤔 is the programming itself.

> Is this much better than I could do by hand? Sure is. Vibe-Coding di-notice atmint loh ya... 😅

Use Claude

no way

You might also want to try implementing the biquads in Transposed Direct Form II. This form is more numerically robust than normal direct forms and is as easy and as efficient to implement. Though, a…

Thanks for the pointer. I will check this out, because it's very much the kind of core low-level thing I'm trying to learn about. And I did do DF2 initially because I was lured in by the "canonical" …

I suspect - but can't verify - that you are feeding it a 24-bit WAV file. This code is all extremely stupid, and the target is to (eventually) go back to a microcontroller hardware setup, so pretty m…

Would you mind looking at expanding this a bit for the new dynamic control functionality I added to the 'convert' binary? See commit ea71138 ("convert: add somewhat realtime control interface") which…

I think this was made obsolete by commit 745e79b ("Update visualize.py: use raw int32 data, just scale the Y axis") which stopped normalizing the input entirely. But I don't know the internals of mat…

This breaks my "SeymourDuncan" test case, which is just "repeat over some random mp3 samples of guitar pickups by Seymour Duncan". That's not a great test-case, but I don't have any actual reasonable…

You are of course correct. A lot of the pots are very random ranges, but this one in particular more random than some. I think I was messing with it in order to get a much clearer response with the t…

The guitar pedal hardware does that 52k sample rate simply because that way it has a integer multiplier from the system clock (150MHz) to the i2s PIO engine that runs at twice the i2s BCLK. (In fact,…

Cherry-picked as commit cc47b99 ("Add a distortion/overdrive effect with clipping modes and tone control")

This is wrong. The quarter_sin[] array explicitly has an extra +1.0 entry at the end, and we do not want to wrap around (and get a zero instead). See 'gensin.c', and that last printf() outside the lo…

This is odd and doesn't even build. There is no "biquad_init_lfp()". Yes, I can see what is intended, but still.. Smells of AI hallucination.

I'm sure you're right, but at the same time I want to make it very clear that the visualization tool is very secondary. IOW, it's a "Don't Do That Then" kind of situation. That visualizer is meant fo…

No, it's 'pots' - pot being short for 'potentiometer' (nobody has the energy to write that word out, so it's pretty universally shortened to pot).

Hopefully all fixed in current -git

As per some of the other pull requests, I can't merge things without DCO sign-off. That said, the only reason I used aplay is that it's simple on linux. But since the project uses ffmpeg anyway, I mi…

This was the right fix (eventually...) but I can only pull requests that have propelr DCO sign-off. I have credited you with a reported-by in the fix commit.
