Musical Instrument Recognition in Isolated Notes and Solo Phrases

By Yuanbo Han and Wenyu Zhang, November 2018.

Methodology

• Gammatone Filtering

• CNN

  

Dataset

RWC Music Database: Musical Instrument Sound

Environment

• MATLAB R2018a
• Python 3.6
  • scipy 1.1
  • numpy 1.14
  • torch 1.0

Note that these are only tested versions, not the least requirements.

Usage

Run gammatone/main.m to perform Gammatone filtering, but please first check the dataset path in line 5 and line 8. To get a grasp of the dependent functions, see gammatone_demo.m for a simple example.

After preprocessing, run cnn/read_data.py to read .MAT files as .NPY format. Then execute CNN.pyto train the neural network. There is an instance (mat_files/XY.mat) for testing CNN.py without above steps.
