flac-cue-split

Split single-file FLAC albums into individual tracks using CUE sheets.

Perfect for Plex users: Plex and other media servers don't support CUE sheets, so albums ripped as a single FLAC file won't display individual tracks. This tool splits them into separate files with proper metadata so Plex can index each track correctly.

Features

• Recursively searches directories for FLAC + CUE pairs
• Automatic CUE file encoding detection (UTF-8, Latin-1, Shift-JIS, etc.)
• Skips albums that are already split
• Safe dry-run by default - see what would happen before committing
• Prompts before deleting source files
• Preserves CUE files after splitting

Requirements

• Python 3.12+
• ffmpeg installed and in PATH
  • Ubuntu/Debian: sudo apt install ffmpeg
  • macOS: brew install ffmpeg
  • Windows: Download from ffmpeg.org and add to PATH

Installation

# Using uv (recommended)
uv tool install flac-cue-split

# Using pipx
pipx install flac-cue-split

# Using pip
pip install flac-cue-split

Usage

# Dry run - see what would be split
flac-cue-split /path/to/music

# Actually split the files
flac-cue-split /path/to/music --execute

# Split and delete original FLAC files (prompts for each)
flac-cue-split /path/to/music --execute --delete

# Split and delete without prompts
flac-cue-split /path/to/music --execute --delete --yes

# Delete sources for already-split albums
flac-cue-split /path/to/music --delete --yes

Output Format

Tracks are saved as {nn}. {track_name}.flac where the number is zero-padded based on total track count (e.g., 01. for <100 tracks, 001. for 100-999, etc).

Options

Safety

• Dry-run by default: Nothing is modified unless you pass --execute
• Deletion prompts: --delete asks for confirmation unless --yes is specified
• Error protection: Source files are kept if any extraction errors occur
• Permanent deletion: --delete permanently removes files (not moved to trash)
