This site is courteous - well done in this age of 'free speech' - but is a little to, er, regimented for me. Thanks and farewell. Pattern-chaser "Who cares, wins"

In that case you'll be programming in Assembly Langauge or C. Maybe C++ if you're lucky enough to program a uC target with enough resources to run programs written in it. Most firmware is written on uCs that have 64k of RAM or less, sometimes a lot less. This can be limiting... :wink: But as I...

Items 1 and 2 are universal and vital. Items 3 and 4 depend on what you program, and how. But don't misunderstand me: I'm not criticising. Twigg's post is good advice.

Conventional wisdom - which is Just Plain Wrong - often refers to progress in software engineering in terms of which language you should learn [next]. You will pick up languages as you need them. But, to progress, you need to learn about design. This isn't easy, and this is only partly because...

I've scanned around the various 'help' offerings that I could find, and can't see how to add a 'signature' automatically to my posts. How is this done, please, and is there a comprehensive how-to for this site anywhere? TIA.

Oo, yes! That sounds a lot like what I'm looking for. Thanks, I'm off to read the full entry now. :smile:👍

My fault. I should've written "Ah, but is it VALID to apply Fourier's Theorem, when music is non-periodic, and that theorem applies only to periodic waveforms?" I'm not saying it doesn't work; it does. But is it valid physics? Edit: I've used Audacity a few times - a very handy utility! :smile:

Ah, but can you? Fourier's Theorem applies only to periodic waveforms, which brings us back to my original question. In the context of non-periodic real-world sound, e.g. music, what is "frequency"?

Sorry, I couldn't think of a catchy title, so I used my long-time motto, as I often do here on the interweb. :wink: My Twitter bio (@Patternchaser) reads thus: "Retired firmware architect; armchair philosopher; Gaian Daoist (tree-hugger). INTJ." My education comprises Maths, Physics and...

But you *can't* view it on a 'scope unless you do a single-scan. On continuous scan, the scope can't sync, possibly because the music waveform isn't periodic? :wink: Also, middle C is indeed 264 Hz, but no instrument (excluding electronic ones) produces a 264 Hz sine-wave when middle C is...

Looking at a music waveform on a 'scope offers a simple and real-world illustration. "Periodic", as applied to waveforms, means that the waveform repeats cyclically, and music does not do this. ... Unless you consider an entire symphony (for example) as a single cycle of a waveform that could...

Setting aside pure sine waves, and looking instead at real-world sound, such as music, I wonder what "frequency" is? Fourier's Theorem seems to be aimed specifically at PERIODIC waveforms, but music (as just one example of real-world sound) is not periodic, as far as I can see. So it is not...
