Hi HN

I’m building ÆTHRA — a programming language designed specifically for composing music and emotional soundscapes.

Instead of focusing on general-purpose programming, ÆTHRA is a pure DSL where code directly represents musical intent: tempo, mood, chords, progression, dynamics, and instruments.

The goal is to make music composition feel closer to writing a story or emotion, rather than manipulating low-level audio APIs.

Key ideas: - Text-based music composition - Chords and progressions as first-class concepts - Time, tempo, and structure handled by the language - Designed for ambient, cinematic, emotional, and minimal music - Interpreter written in C# (.NET)

Example ÆTHRA code (simplified):

tempo 60 instrument guitar

chord Am for 4 chord F for 4 chord C for 4 chord G for 4

This generates a slow, melancholic progression suitable for ambient or cinematic scenes.

ÆTHRA currently: - Generates WAV audio - Supports notes, chords, tempo, duration, velocity - Uses a simple interpreter (no external DAWs or MIDI tools) - Is intentionally minimal and readable

What it is NOT: - Not a DAW replacement - Not MIDI-focused

Why I made it: I wanted a language where music is the primary output — not an afterthought. Something between code, emotion, and sound design.

The project is open-source and early-stage (v0.8). I’m mainly looking for: - Feedback on the language design - Ideas for musical features worth adding - Thoughts from people into PL design, audio, or generative art

Hi HN,

We have open-sourced Voiden.

Most API tools are built like platforms. They are heavy because they optimize for accounts, sync, and abstraction - not for simple, local API work.

Voiden treats API tooling as files.

It’s an offline-first, Git-native API tool built on Markdown, where specs, tests, and docs live together as executable Markdown in your repo. Git is the source of truth.

No cloud. No syncing. No accounts. No telemetry.Just Markdown, Git, hotkeys, and your damn specs.

Voiden is extensible via plugins (including gRPC and WSS).

Repo: https://github.com/VoidenHQ/voiden

Download Voiden here : https://voiden.md/download

We'd love feedback from folks tired of overcomplicated and bloated API tooling !
