Jamaisvu

A work-in-progress improvement upon Will Drevo's Dejavu project for audio fingering printing in Python. The aim of Jamaisvu is to be optimised and effective enough to be used as a sound identifier for DJs at Lafayette College's WJRH Radio.

I occasionally write about the progress of Jamaisvu on my website, and features and bugs I am currently working on can be viewed on my Trello board

The main goals for Jamaisvu over Dejavu is:

• Provide more features
  • Detailed Information about songs (e.g. Artist, Album, Explicit, etc...)
  • Support API calls to be able to run in the background
  • Provide support for user entry and modification for mislabelled data
• Provide much faster fingerprinting times via optimisations and GPU acceleration
• Be integrated with Renan Dincer's Teal, which is a nice package for organising and storing radio shows

Eventually this will be used as the backend for WJRH Assistant

Getting Started

Tested only on MacOS and Ubuntu 16.04

Prerequisites

What dependencies you will need to run Jamaisvu:

• Numpy
• Scipy
• Pycuda
• AcoustID
• Mysql
• Mysql-config
• Spotipy (You will need to set this up with your own Spotify account and keys in your PATH!)
• Pymsgbox
• Pydub
• Pyaudio (also portaudio19-dev)
• Reikna
• Scikit-cuda

Installing

Ensure that you have a MySQL Database instance setup and running on your local machine and then setup a database for Jamaisvu with:

$ mysql -u root -p
Enter password: **********
mysql> CREATE DATABASE IF NOT EXISTS jamaisvu;

Hello World

You can use the JMV_Test.py to test to make sure your installation is working correctly

$ python JMV_Test.py [path to config.yaml] [path to music file]

The programme should fingerprint your file, store it in the database, read the file again, and identify it using the database. It should return something like:

Result:
song_genre : canadian pop
confidence : 181436
offset_seconds : 0.0
match_time : 6.18130493164
offset : 0

song_id : 1
song_name : Often - Kygo Remix
file_sha1 : 4EC99324791D7AF5A497FB693FF1DD3DBD3420A1
