flamp3

Convert FLAC files to MP3 in batch, with adjustable LAME quality
A companion Go utility using a shell pipeline (flac -c -d | lame).

---

Features

• Selective: only processes .flac files
• Recursive mode (-recursive) preserves directory structure
• Skip existing MP3s to avoid re-encoding
• Adjustable LAME VBR quality (-quality, 0=best → 9=worst)

---

Requirements

• flac
• lame
• sh (for the pipeline)

---

Installation

git clone https://github.com/verkaro/flamp3.git
cd flamp3
go build -o flamp3 main.go

---

Usage

# Single FLAC to MP3 at default quality (6)
./flamp3 -out mp3s album.flac

# Convert entire folder to high quality MP3s
./flamp3 -out mp3s -recursive -quality 2 ~/music_library

Flags:

• -out — Output root directory (creates it if needed)
• -recursive — Recurse into input directories
• -quality — LAME VBR level (0=best, 9=worst; default 6)
