Show HN: LatentScore – Type a mood, get procedural/ambient music (open source)

Source: Hacker News

Introduction

I’ve used Generative.fm for years and love it, but I always wanted to describe what I was in the mood for instead of scrolling through presets. So I built LatentScore.

How It Works

• You type a text description of anything — from “mountain sunrise” to “neon city”.
• The system generates a procedural/ambient stream that matches that mood.
• It runs locally, with no account, no tracking, and no ads.

Under the hood is a custom synthesizer driven by sentence embeddings, not a generative AI model (although you can choose to use one). This means:

• No GPU required.
• No API calls.
• Playback starts almost instantly.

The whole project is open source.

Programmatic Use

If you’re a developer, you can use LatentScore as a Python library:

pip install latentscore

One line of code renders audio, but you can also use the web player for everyday listening.

Limitations

Fair warning: LatentScore is still in alpha. The synth has limits, so don’t expect full songs or vocals. It’s designed for ambient/procedural music—ideal for focus music or background atmosphere.

Call for Feedback

I’d love to know what vibes you try and whether they land!
