Imagine an unsorted music library with unknown or badly named and tagged audio-files. This program should help to bring a whole music-library into the right directory structure and tag each file with the right song information (i.e. artist, album, track-name) set as ID3-tags. The desired directory structure looks as following:
├── <artist>
│ └── <album>
│ ├── <track>
│ └── ...
├── <artist>
...
Therefore we implemented a python command line interface which draws on the Gracenote Recognition C API to get track information by its audio sampels and FFmpeg to decode mp3-files.
1. Load the mp3-file in python
2. Call the C function with the mp3-file
2.1 Decode packets via ffmpeg
2.2 Lookup raw audio samples via GNSDK
3. Reset ID3-tags file with result of the lookup
4. Place file in the right folder
- python (>= 3.5)
- FFmpeg libs (avutil,avcodec,avformat,swresample,swscale)
- GNSDK libs + Account with license file, client tag and id
- unix pkg-config and its python interface (use:
pip install pkgconfigto install)
- Install the wrapper:
- Open file ./wrapper/setup.py and set
gnsdk_dirvariable to your path to the GNSDK home directory - Type
make
- Open file ./wrapper/setup.py and set
- Set client tag, id and license path:
- Open ./python/leadSorterCL.py and set the identification (can be retrieved from your gnsdk account)
python3 leadSorterCL.py [-h] [-m] [-p] [-d DESTINATION] search_path

positional arguments:
search_path path to music directory
optional arguments:
-h, --help show this help message and exit
-m, --move move files: default will copy files
-p, --print print info: default won't print extra info
-d DESTINATION, --destination DESTINATION
destination path: path to new sorted directory
