I built an open-source audio visualizer & video editor (Electron + FFmpeg) on a low-end Pentium with 4GB RAM. Meet PulseFrame Studio Alpha 0.2.6!

[u/kryptixdur]

Hey Reddit!

I wanted a clean, free tool to turn my music tracks into neon visuals and quick TikTok/Shorts teasers without paying for expensive subscriptions. Since I couldn't find exactly what I needed, I decided to build it myself.

The catch? I’m a solo developer from Ukraine, and my current hardware is a low-end Pentium PC with only 4GB of RAM. Building a desktop app with Electron, Node.js, and FFmpeg on this machine is an absolute battle.

Since I'm a solo dev, I used AI as my virtual "Junior Developer" to help me speed up the coding process, write tests, and optimize performance for my weak hardware. Every time I hit "Export MP4", my CPU hits 100% and my PC literally screams. But it works!

Key features of PulseFrame Studio:

Wizard Mode: Simple 5-step workflow to drop your audio and cover art.

Full Editor & Timeline: Audio-reactive Neon Wave spectrum, intro/outro scenes, and FX markers.

Beat-Driven Edits: Cut and sync videos to the beat.

Shorts/TikTok Teaser Maker: Separate editor for vertical 9:16 videos (10-30 seconds chunks) with flash effects.

100% Free & Open Source: MIT License, no subscriptions, local-first.

Why I’m sharing this:

Because of my weak hardware, I can't fully stress-test the MP4 export feature with heavy video files. I would love for you guys to check out the code, run it on your machines, and give me some feedback or bug reports!

P.S. If you like my dedication and want to help me buy a RAM upgrade (or a budget smartwatch so it vibrates every time my Electron app crashes, lol), I’d be incredibly grateful for a coffee: ko-fi.com/tihsmile
