music-recognition-tool 1.2.1

Identify music files using Shazam, write ID3 tags, rename and organize

🎵 Music Recognition

Bulk music identification and tagging tool — bring order to your chaotic music collection.

Automatically identify unknown music files using Shazam, write ID3 tags, rename files, and organize into Artist/Album folders.

✨ Features

• 🔍 Identify tracks via Shazam API
• 📝 Write ID3 tags — title, artist, album, year, genre
• 📁 Rename files — customizable templates like {artist} - {title}.mp3
• 🗂️ Organize — automatic Artist/Album folder structure
• ⚡ Async processing — concurrent requests with rate limiting
• 🔄 Format conversion — WAV, FLAC, M4A, OGG → MP3
• 📊 Export reports — JSON/CSV for processed files
• 🛡️ Safe — dry-run mode to preview changes

🚀 Quick Start

Installation

# From source
git clone https://github.com/formeo/music_recognition.git
cd music_recognition
pip install -e .

# Or install dependencies only
pip install -r requirements.txt

Requirements

• Python 3.9+
• FFmpeg (for audio conversion)

# Ubuntu/Debian
sudo apt install ffmpeg

# macOS
brew install ffmpeg

# Windows
winget install ffmpeg

Basic Usage

# Recognize and tag all files in a directory
music-recognize /path/to/music

# Also rename files to "Artist - Title.mp3"
music-recognize /path/to/music --rename

# Organize into Artist/Album folders
music-recognize /path/to/music --organize --output /sorted

# Preview changes without modifying files
music-recognize /path/to/music --rename --dry-run

📖 Usage Examples

Command Line

# Process single file
music-recognize song.mp3

# Process directory with custom template
music-recognize /music --rename --template "{artist}/{album}/{title}.mp3"

# Export results to JSON
music-recognize /music --output report.json

# Force re-recognition of already tagged files
music-recognize /music --force --overwrite

# Quiet mode (minimal output)
music-recognize /music -q

# Verbose mode (detailed logging)
music-recognize /music -v

Python API

import asyncio
from music_recognition import MusicRecognizer, recognize_and_tag

# Simple one-liner
asyncio.run(recognize_and_tag("/music", rename=True))

# Full control
async def process_collection():
    recognizer = MusicRecognizer(
        max_concurrent=5,
        delay_between_requests=0.5,
    )
    
    stats = await recognizer.process_directory(
        source_dir="/music",
        output_dir="/sorted",
        write_tags=True,
        rename=True,
        rename_template="{artist} - {title}.mp3",
        organize=True,
        skip_recognized=True,
        dry_run=False,
    )
    
    print(f"Recognized: {stats.recognized}/{stats.processed}")
    print(f"Success rate: {stats.success_rate:.1f}%")

asyncio.run(process_collection())
