In plain English

Flac2MP3 is a simple command-line tool that converts FLAC audio files into MP3 format. The creator built it to solve a personal frustration: their music app downloads songs in FLAC, which video editing software like Adobe Premiere Pro doesn't support. Instead of hunting for online converters every time, they wanted a single command to do the job locally. Using it is straightforward. You open a terminal and type the tool's name followed by your file path, and it hands you an MP3 version. Under the hood, it relies on FFmpeg, a widely-used audio and video processing engine, to handle the actual conversion. The tool itself is essentially a thin wrapper that makes FFmpeg easy to call for this specific task. This is for anyone who works with audio files and needs MP3s quickly, especially video editors, podcasters, or content creators. For example, if you download a song in FLAC and need it in a video timeline that only accepts MP3, this saves you a trip to a web converter and keeps you in your workflow. The project is intentionally minimal. It currently only converts FLAC files and accepts a file path as input. The README hints at possible future additions like supporting more formats and options, but for now it stays focused on its single purpose. You will need Go and FFmpeg installed on your computer to build and run it.
