   Hi! I'm Freeman, a research engineer at Sesame. I'm the developer of the turnbench.sesame.com website and also a co-author. For the past bit, I've been working on models for real-time conversation at Sesame. We wanted an eval

   Yeah there is a filter between 1.2 and 20 mph

   In Lyft's defense, they are providing it anonymized under the NYCBS Data Use Policy. They also aren't providing the exact GPS routes, which is why OSRM is used to calculate the shortest path instead.

   Thank you so much! That means a lot.

   It definitely will if it blows up more. I'm willing to eat it for now because I think it's art that more people should see!

   Yeah, unfortunately, I think I posted that one initially without the Show HN prefix, so I don't think I can edit the text there.

    I see, yeah I use Next.js pretty regularly, you mean on hot reload then? You still need to write your content as Markdown or something else, right? I feel the editors of Substack give some nice features like shortcuts for bold, italics. Wha

    https://www.beatsync.gg/ I launched this on HN over the summer, but it's millisecond-precise audio synchronization for multiple devices, performed purely in the browser! I'm sitting at around 5K daily active users

    Thanks for bringing this up! Made an issue to look into this.

    Yeah, at one point I had manual controls to adjust the delay to debug. I'll add that back.

    Practically, the network jitter is averaged out in the clock synchronization calculations, and even output latency is remarkably well-behaved. Have you tried it on different devices? It is only noticeable when there's an external devic

    Haha yeah guarantee is a strong word. I just mean that it’s good enough to not be noticeable (even within the same physical room)

    Thank you! Very appreciated kind stranger :)

    Oh I see, yeah I was wondering why it looked like that since on my computer responsive view looked great. Will look into this, thank you.

    Miraculously pulled it off with a change I made today

    Made an update so it should be good on most!

    It doesn't at the moment, but I think it probably should. There's a non-trivial amount of clock drift that can happen over long periods of time.

    Thanks for the heads up! Just added a license to the repo.

    Yes! The very next step.

    It works on other platforms! Just not as smooth as Chrome.

    Yup no microphone. It's all clock sync

    by freemanjiang 1y ago

    Yeah the threshold is pretty brutal, but it is enough. Experimentally, I'd say you need under 2-3ms but even at 1ms you can start to hear some phase differences. Most of the time, I think my synchronization algorithm is actually sub-1m

    by freemanjiang 1y ago

    Great question! There's two steps: First, I do clock synchronization with a central server so that all clients can agree on a time reference. Then, instead of directly manipulating the hardware audio ring buffers (which browsers don&#x

    Thank you for the kind words! Yeah, I think it gets a lot more complicated once you start dealing with speaker hardware. It pretty much only works for the device's native speaker at the moment. The instant you start having wireless s
