  • Very cool. Number keys and QWERTYU (or clicking the rows on the right) trigger the "modes" in isolation, which are surprisingly microtonal.

    Also you can draw your own drums! What! That's so cool

  • there's an amazing video on youtube about how metal bar/gong instruments (like gamelans) have different overtones, and regular western intervals instead of being consonant (like with vibrating strings) are dissonant - even perfect 5ths - and a totally different set of intervals are consonant (slendro and pelog tunings are a bit different for this reason).

    thinking about it, each drum here would have totally different ideal scales to the others.

    this is cool.

  • What a great visualizer tool!

    Observation: I never saw the link between Wave Equation Solvers, Finite Element Analysis (Eigenvalues, Eigenvectors, etc.) and Cymatics -- until I visited the above web page!

  • This reminds me of a tongue drum I have. Have you thought about building an iterative solver for specific scales?

    It would be interesting if you could simulate and then print (or laser cut) your own instrument on demand.

  • Separate to the concerns about privacy others have, I found some ear-splitting pitch errors with making very narrow asterisk-shaped drums with a number of spokes not divisible by 2 or 3. Good thing my volume was low.

  • Try `1 + 0.16cos(4t) + 0.08cos(12t + pi/6) + 0.04cos(36t + pi/3) + 0.02cos(108t + pi/2)`

  • Anyone else seeing "net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH"? Happens both in Firefox mobile and another browser that's a thin wrapper around Google's Chromium Webview. I'm surprised nobody mentioned it yet if firefox and chromium both struggle with this site. Or do they use a common TLS engine on Android?

    Sadly http is not supported, it forces https for what I understand (from the title) to be a little web toy

    Edit: same issue on Firefox desktop on Linux. It gets the redirect from github.io and then a ciphersuite mismatch. I now guess the host got some faulty update and it's not a me issue

  • Hi, I was propagating DNS nameservers, sorry for the delay.

    Let me know if you still face any issues.

    EDIT: The DNSSEC validation error was caused by a cached TTL mismatch during the nameserver migration. I've temporarily disabled DNSSEC while it clears up and am getting it sorted out.

  • This is so dang cool. I’m sorry that all people can do is complain!

  • What, didn’t you want hundreds of companies track you while you try to get the audio work on a drum simulator?

  • This is brilliant! I wish I had seen this a few years back!

    Q: Generating higher quality sounds with a specified duration (e.g. within a 300ms margin) -- is it possible with your approach, is it hard, how would you go about that?

    I'm asking because a few years back I had an idea for a breathwork/meditation app that would allow you to connect / control the breath duration using a gong sound. Example pattern: 4s in, 4s wait, 8-10s out. Next: use a feedback loop with the real user breathing pattern, slowly extend towards the goal.

    Ended up with scaling it down to a "dot to stare at" + basic gong, because I realised how ridiculously chromatically complex the sound is. (my approach was to synthesise an envelope with a shape determined by time -- pity the fool who thought it was easy or even made sense!)

    I got +100k people visiting it and still a couple dozen daily users running a 5+ min session, so I'm happy with it. But, the itch is still there, so I'd love to revisit my old nemesis so to speak :)

    Also, if you want to chat about this, hit me up sonnet.io/posts/hi !

  • This website has a list of data vendors 200 pages long, and it forces you to uncheck each one if you don't consent. I decided to close the tab rather than deal with this illegal dark pattern.

  • So in Dutch one expression for "that makes no sense" is "dat slaat nergens op", which literally translates to "that doesn't hit (slap, beat) anything".

    A ruder variation of that is "dat slaat als een … op een drumstel", or "that hits like a … on a drum set".

    For some reason I felt like sharing this trivia.
