Meta-Music

Meta-Music is an open-source project that lets people add metadata to their Music library using audio recognition system for accurate retrival of data incase of mismatched song names.

Note: since, this branch uses audio recognition to find correct song names which were mismatched by the API provider. And the audio recognition system only recognizes songs within the local database, its not ideal for real world use cases. Please refer to pypi_package branch for your use.

Quickstart

   `
   $ git clone https://github.com/unique1o1/Meta-Music 
   $ cd Meta-Music
   $ sudo pip install -r requirements.txt
   $ python3 app.py
   `

Database Setup

Database Configuration

   $ nano Metamusic/config

Using docker

   cd Meta-Music
   docker build -t meta-music:latest . 
   docker run --rm -ti -v /your/local/pathto/Music:/music meta-music:latest

Creating database on docker

   docker run --name postgres-sql -e POSTGRES_PASSWORD=0 -d postgres
   docker exec -ti -u root postgres-sql bash
   psql -U postgres
   create database metamusic

Database table Creation

   $ python3.6
   >>> from Metamusic import database
   >>> database.metadata.create_all()

Note: do change IP in /static/dist/Worker.js to your docker containers IP

   docker inspect <your container's name> | grep -i 'ipaddress'  //to find your docker container's IP

Fingerprinting

To start filling the database with your music's fingerprints follow the instruction below:

   python3.6 metamusic.py -l 10 -f /path/to/your/Music/file/or/directory

Recognizing from File/ Directory

   python3.6 metamusic.py -l 10 -r file /path/to/your/Music/file

Recognizing from Microphone

   python3.6 metamusic.py -r mic 10

Note: Recognizing from Microphone doesn't work for docker containers for now

Tuning

Inside Metamusic/fingerprint.py, you may want to adjust following parameters.

FINGERPRINT_REDUCTION 
PEAK_SORT 
DEFAULT_OVERLAP_RATIO 
DEFAULT_FAN_VALUE 
DEFAULT_AMP_MIN 
PEAK_NEIGHBORHOOD_SIZE 

These parameters are described in the Metamusic/fingerprint.py in detail. Read that in-order to understand the impact of changing these values.

Demo

Note for MacOS users: If you experience problems with fork in macOS, put OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES in your environment variable to fix the issue. This is an issue with macOS 10.13 where Apple changed the way fork() works on the OS which is incompatible with Python fork().
