mp3_speedrun

Test different versions and/of programs to see which can decode and encode the fastest and generate a CSV of the results. (WIP!!)

Programs and pipe chains include:

• SoX (2012, +opus, manual rebuild)
• LAME
• Helix
• ffmpeg
• SoX → Helix
• ffmpeg → Helix

Methods include:

• Generic stream redirection, (command prompt) uses a thread of total CPU usage across 2-3 processes
• Asynchronously reading and writing stream blocks to maximize CPU
• Simply timing dedicated external programs/scripts that perform the same actions

ffmpeg decodes audio significantly faster than SoX

stupid SoX requires a temp file to merge audio tracks together (recent versions I think)

To run:

bun run main.js

This project was created using bun init in bun v1.1.0. Bun is a fast all-in-one JavaScript runtime.

Exclusively created for Windows/Bundows.
