      So in Dutch one expression for <i>&quot;that makes no sense&quot;</i> is <i>&quot;dat slaat nergens op&quot;</i>, which literally translates to <i>&quot;that doesn&#x27;t hit (slap, beat) anything&quot;</i>.<p>A ruder variation of that is <i>&quot;dat slaat als een … op een drumstel&quot;</i>, or <i>&quot;that hits like a … on a drum set&quot;</i>.<p>For some reason I felt like sharing this trivia.
      • spockz12 hours ago
        I never heard “op een drumstel”, always “op een varken”. So it would be “Dat slaat als een tang op een varken.” Or “That hits like pliers on a pig.”
        • isoprophlex11 hours ago
          &quot;Als een tang op een varken&quot; is the common one for me as well. Runner up: &quot;Als een lul op een stadsbus&quot; (it makes as much sense as a dick against a city bus)
          • vanderZwan11 hours ago
            Perhaps the &quot;hits like an x on a y&quot; family is larger than any of us thought?
        • vanderZwan11 hours ago
          Could be a regional thing. I&#x27;ve heard the pliers-on-a-pig version too, might be more common.

    This is brilliant! I wish I had seen this a few years back!<p>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?<p>I&#x27;m asking because a few years back I had an idea for a breathwork&#x2F;meditation app that would allow you to connect &#x2F; 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.<p>Ended up with scaling it down to a &quot;dot to stare at&quot; + 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!)<p><a href="https:&#x2F;&#x2F;untested.sonnet.io&#x2F;notes&#x2F;projects-and-apps-i-built-for-my-own-well-being&#x2F;#h-sit" rel="nofollow">https:&#x2F;&#x2F;untested.sonnet.io&#x2F;notes&#x2F;projects-and-apps-i-built-f...</a><p>I got +100k people visiting it and still a couple dozen daily users running a 5+ min session, so I&#x27;m happy with it. But, the itch is still there, so I&#x27;d love to revisit my old nemesis so to speak :)<p>Also, if you want to chat about this, hit me up sonnet.io&#x2F;posts&#x2F;hi !

    This is very fun to play with and design different drums. I was able to make one that had 4 connected but distinct regions giving different pitches, then within each of those regions (which look like 4 lobes of different sizes) where you tap on that region will further change the sound! Then I realized I basically just made a hand pan.
  • OgsyedIE7 hours ago
    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.

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

        I am sorry about that, I thought I removed the consent banner along with the ads completely this morning, then I came back here and realized Google AdSense still had the consent banner published, I forgot to disable it, it doesn&#x27;t show up to me as I am not EU I guess. Should be gone now, please let me know if something else still shows up.

    This website has a list of data vendors 200 pages long, and it forces you to uncheck each one if you don&#x27;t consent. I decided to close the tab rather than deal with this illegal dark pattern.
  • jmole16 hours ago
    This reminds me of a tongue drum I have. Have you thought about building an iterative solver for specific scales?<p>It would be interesting if you could simulate and then print (or laser cut) your own instrument on demand.

      It worked for me by unmuting my ringer and raising my volume. Agree UX isnt great.
  • codedokode5 hours ago
    It seems to simulate only the membrane, and not the body of the drum, so no bass drum, no snare and no hi-hats?
  • prabhanjana_c4 hours ago
    actually too cool. very addictive, while changing different parameters and playing.
  • andai19 hours ago
    Very cool. Number keys and QWERTYU (or clicking the rows on the right) trigger the &quot;modes&quot; in isolation, which are surprisingly microtonal.<p>Also you can draw your own drums! What! That&#x27;s so cool
    • plaguuuuuu14 hours ago
      there&#x27;s an amazing video on youtube about how metal bar&#x2F;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).<p>thinking about it, each drum here would have totally different ideal scales to the others.<p>this is cool.
      • olelele1 hour ago
        A friend told me that a Dutch university ordered a custom gamelan tuned chromatically. It was a total failure and sounds terrible. The gamelan are made one by one w the oldest member of the group making his first and everyone tuning theirs from his down in turn, IIRC.

    I tapped twice and got nothing but sketchy popup ads suggesting I need to install a VPN. Does it work on safari mobile for anyone else?
    • phoghed7 hours ago
      Yeah, just have to make sure your phone isn’t on silent for sound effects in the browser.<p>Also if you use an ad blocker, which I highly recommend, you wouldn’t have seen any of the ads or other stuff most of the comments can’t seem to figure out how to avoid.
      • Waterluvian7 hours ago
        I have an adblocker. I guess it just missed.<p>It’s sad though that such a non-corporate site has such nasty ads though.

        I&#x27;ve read hundreds of papers in my mathematics career, and they – good and bad – almost always blend into eachother and turn into a diffuse fog in my memory, where they&#x27;re identified by &quot;that good one by Johnson-something-I-think.. no the 90s one I think&quot;.<p>There are very few exceptions. Kac&#x27;s drum paper is one. It&#x27;s so nicely written!

    I love it. I wish I could select materials.
    • tanderson9218 hours ago
      Selecting different materials would not change much. Call the frequencies \lambda_1, \lambda_2, \lambda_3...<p>You can prove that changing the material has no effect on the relative frequencies: \lambda_2 &#x2F; \lambda_1, \lambda_3 &#x2F; \lambda_1, etc. are completely independent of the material.<p>The shape is the determining factor; changing the materials (and hence the wave speed) just dilates the whole spectrum.
    • BaselAshraf8118 hours ago
      There&#x27;s actually a &quot;ring-out&quot; slider and a &quot;mallet&quot; width slider under the drum already.<p>Ring out controls how fast the higher modes decay (basically stiff vs soft material), The mallet width controls how many modes a strike can even reach, since a real mallet can&#x27;t drive the high frequency ones very hard.<p>No labeled presets like &quot;wood&quot; or &quot;metal&quot; though, just raw sliders. Would be a fun addition if someone wants to map a few physically sensible combos to buttons. PRs Welcome!

    The tone is kind of snippy. It refuses to play when there would be numerical artifacts (&quot;there would be numbers, and they would be wrong&quot;) and if your drawn shape self-intesects it complaint rather than just giving a reasonable answer with a warning (minimum crossing width, separate bodies).<p>Overall a cool tool, but pretty annoying. I point it out not really to criticize this project, but because I see a trend in software that has a holier-than-thou sort of paternalistic tone. LLMs are obviously rife with this, but I also see interfaces from some humans that give me the vibe of a snooty Parisian waiter.

    The title alone sounds like this would be interesting, but I&#x27;ll never know if it is because it has a trackers popup listing thousands of &quot;partners&quot; and a load of &quot;legitimate interest&quot; boxes ticked by default. This is Daily Mail level stuff, immediate back button for me.

    Not a fan of the cookie dialog. Had to close the page as there was no easy way to reject the ad cookies.
    • andrelaszlo7 hours ago
      Yeah, I&#x27;m no GDPR expert but it seems completely unreasonable that the &quot;legitimate interest&quot; numbers add upp to 2825. Even though there&#x27;s probably some overlap, the biggest category is &quot;Measure advertising performance (695 partners included)&quot;. How does this dialogue help me control who gets my data or how it will be used?
      • slhck7 hours ago
        It&#x27;s not even unreasonable, it&#x27;s illegal under GDPR. You have to provide a reject all option (for rejecting all non-necessary cookies).

          I didn&#x27;t even know that was a meme. I have vibe coded various projects too, but I find the overzealous monetization very much off-putting.
