I'm Sam, I make sample libraries (as FrozenPlain). These sample libraries run inside Floe, my audio plugin for Linux, macOS and Windows. It's designed for musicians, composers and producers - typically people involved with film/TV/game scoring or ambient music. I open-sourced it primarily because I'm very fond of this philosophy and I want to open the door for serving a wider audience than just my own libraries.

It's totally free, no sign-ups. You'll need a DAW. To try it: - Download and install Floe: https://floe.audio - Download your choice of free packages: https:floe.audio/packages#community-packages or https://www.frozenplain.com/product/music-box-suite-free - Install the packages using Floe's 'Install Package' button. https://floe.audio/docs/installation/install-packages

I'm curious about HN's thoughts regarding the open-source nature, directions I could take for expanding the audience, and the Lua based sample-library it has (https://floe.audio/docs/develop/develop-libraries). Thanks.

Is this essentially "roll your own VST plugin" or something else?

i couldn't find any information about it but i still see an AGENTS.md file at the root of the source tree so: how much AI was used in the making of this? how was it used?

Since early 2026 it's mixed AI and handwritten. Before that it was mostly written by hand. Quite a lot of the code goes back to 2018 even. Typically, I do back and forth with Claude Code agents on new features and bug fixes, reading and editing code along with it.
