Instruments.append(rwc.Instrument(rwc_path,instrument_nums,allowed_styles,allowed_case,allowed_dynamics)) #for each instrument construct an Instrument object Instrument_nums= #bassoon,clarinet,saxophone,violin # construct lists for the desired dynamics,styles,musician and instrument codes Feature computationĬompute the features for a given set of audio signals extending the "Transform" class in transform.pyįor instance the TransformFFT class helps computing the STFT of an audio signal and saves the magnitude spectrogram as a binary file. The score file as a note on each line with the format: note_onset_time,note_offset_time,note_name. The folder with the must contain the scores: 'bassoon_b.txt','clarinet_b.txt','saxophone_b.txt','violin_b.txt'. Score-informed separation of Bach chorales from the Bach10 dataset into bassoon, clarinet, saxophone, violin in examples/bach10_scoreinformed/separate_bach10.py:

pkl file you can download from this address is the output directory where to write the separation.Separate music into vocals, bass, drums, accompaniment in examples/dsd100/separate_dsd.py :
#Mtg spy network combo code
We provide code for separation using already trained models for different tasks. In the 'evaluation' folder you can find matlab code to evaluate the quality of separation, based on BSS eval.įor training neural networks we use Lasagne and Theano. The later is a good example for training a neural network with instrument samples from the RWC instrument sound database RWC instrument sound dataset, when the original score is available. We provide code for feature computation (STFT) and for training convolutional neural networks for music source separation: singing voice source separation with the dataset iKala dataset, for voice, bass, drums separation with DSD100 dataset, for bassoon, clarinet, saxophone, violin with Bach10 dataset. In the 'examples' folder you can find use cases for the classes above for the case of music source separation. Additionally, you can find classes to query samples of instrument sounds from RWC instrument sound dataset. This repository contains classes for data generation and preprocessing and feature computation, useful in training neural networks with large datasets that do not fit into memory.
