Meta Segment Anything Model Audio

Posted by megaman821, with replies from many commenters. 16 December 2025. Hacker News discussion thread, 223 points.

The thread is community reaction to a Meta announcement. Its evidence is a mix of hands-on trials, secondhand reports from GitHub issues and opinion. Results are described as inconsistent, and hardware needs as high.

DIY synths database

Atarity. Updated 11 October 2026. Landing page for a curated database.

The landing page describes a curated collection of 95 DIY-friendly hardware synthesizers, all open source. The project list is not in the page HTML. Only the page text and the RSS feed of ten recent entries were read.

How I reverse engineered a commercial spatial audio effect

Posted by epestr, with replies from many commenters. 11 October 2026. Hacker News discussion thread, 134 points.

The poster who wrote the blog post also answers most replies. The thread splits between technical interest and strong dislike of the sound. It also gathers alternative tools, hardware advice and personal audio tastes.

Eigendrum - draw a shape and hear it as a real drum

Basel Ashraf. Undated. Interactive web tool with a built-in explanation.

The page is a working instrument plus a long explanation of the physics behind it. The developer states how the sound is computed and how the solver is checked. The audio itself was not heard for this summary.

Music Finetunes | ElevenLabs Documentation

ElevenLabs documentation. Undated. Vendor product documentation page.

The page is product documentation, not an evaluation. It covers intended users, upload rules and limits, and tips for datasets and prompts. Its copyright rules are stated in strong terms.

GitHub - leolabs/ableton-js: Control Ableton Live with Node.js

Not stated in the README text (repository owner leolabs). Undated. Open source project README.

The README covers setup, example code, the message protocol and a few findings about Live. It states that the package is a work in progress. It also carries a sponsored note for the author's own product.

ossia/score: ossia score, an interactive sequencer for the intermedia arts

Not stated. Undated. Open source project README.

The README is mostly a feature list, install notes, build badges and contribution advice. Its claims are the project's own. It shows a screenshot, which was not viewed.
