Are there any LLMs being widely used for audio classification? I know VLMs are being used a lot in image stuff. It always seems kind of silly to me to throw everything at an LLM. I know they’re huge and can automatically handle a huge number of tasks but something in me finds it wasteful when we could be creating easily trainable, cheap to run bespoke models for a lot of stuff

There are LLMs that support audio input, similar to those with vision support. From my testing of open weights LLMs with audio support, they basically are only trained to recognize audio as an alternative to text input, they treat audio as basically equivalent to a transcript, and can't recognize or distinguish things like music, accents, background sounds, etc. So they're only really good for transcribing or summari…

Have you had any luck fine tuning one with musical data for classification or music-aware QA? I've been hacking on https://trebel.la/ which I would like to be a music practice companion, and the biggest missing feature is actually useful audio-based feedback pipeline.

My current approach, not yet validated, is trying to generate training data from masterclass recordings on Youtube, and then fine tuning MOSS-audio on a bunch of those. But I'm interested if there are better models, or large training sets I don't know about.

This is the coolest thing on HN that I've seen in a minute. The whole thing is a perfect blend of ideas with the end result of something that feels... magical. Honestly this is the highest inspiration to me as a builder as I just want to create magical experiences, even if they are just small oddities.

Agree, this was really a beautiful thing to see!

I might be misunderstanding your comment but the display is run/powered by the board so all you need to do is provide power to the board. For e-ink it uses no power to "hold" an image, only to write/refresh (sorry if I'm telling you something you already know!). So reiterate, with a 2000mAh lipo battery I should be able to drive the board _and_ the screen for over 3 years if I only refresh it at most once every 4 hou…

Yeah no we're aligned; I have some raspis that I'm interested in doing long term battery stuff with (remote sensing and the like) and it definitely does seem like connectivity is the huge battery killer, like even if you wake up only periodically to take a reading or update an epaper display, the cost in battery just to negotiate a wifi connection and do tcpip and http things is awful. And then you're stuck with a de…

It only can last a couple weeks, so isn't really practical. Search for other e-ink calendar projects using the rpi zero

Contrary to the Great Man version of how we mostly talk about history, scientific discoveries, technological breakthroughs and such have historically often occurred multiple times in multiple places often in close proximity time-wise but otherwise completely unrelated to each other. This of course makes sense if you consider that history seems to be primarily driven by material conditions (e.g. steam engines were kno…

My favourite example of this is calculus, followed closely by heavier-than-air flight.

I've been leveraging Birdnet-2.4 as well, but also ultrasonic-pass and activity-v1 to do broader detection with an ecological targeted microphone. This means I can capture not just bird sounds but also bats and some insects, and acoustic events such as jets and cars. Applying heterodyne transformations to the bat recordings makes them audible which is fascinating, especially when you catch them in a feeding frenzy. S…

Do you use AudioMoth embedded mic?

That’s the one, in their outdoor casing

My favourite example of this is calculus, followed closely by heavier-than-air flight.

I think there is ample evidence that the Wright brothers were (unlike many other inventors) uniquely suited to solving the problem of heavier-than-air flight, as they solved several open problems that nobody was making progress on (the main ones being control authority, propeller designs, the scientific basis for wing designs, and the ability to test designs and practice without dying) -- they even discovered and solved previously-unknown problems (such as adverse yaw, something their contemporaries should've independently discovered if they were on the right track).

A full rundown would be too long but [1] is a pretty good video going through the history of flight and how most of the other candidates for "first flyers" people bring up don't count and how it's difficult to argue that any of their contemporaries were even close to the Wrights.

That's indeed a cool project and it's this kind of stuff that makes HN a unique corner in this digital world. I can classify this project with [1](Ranked #3 as the most upvoted Show HN of all time), [2](#4) and [3](#6) as non pure-software products that happen to also integrates hardware as well.

The only thing I wish to be added is a short video showing the actual frame in action to express motion and sound so I can better feel it. While the provided image (hero.jpg) gives me a sense of the product, I just can't smell it yet. I visited https://fugleramme.arnegiacomo.dev/ hoping for a live feed but it seems just a static image.

Kudos for the author and I hope we can see the next iteration!
