Usage

Simple usage

Simple Python script to use DataSounds module to sonify dataset.

from DataSounds.sounds import get_music, w2Midi
import numpy as np

data = np.random.rand(24)
music = get_music(data)
w2Midi('my_musica_data', music)

w2Midi writes a .midi file inside the current directory. In this case my_music_data.midi will be saved on disk.

Play MIDI files inside Python is a little bit tricky, and it is possible using the compilation of Pygame library.

To not bring this dependency inside DataSounds, we try to use the system player. For Linux you could install timidity (apt-get install timidity) or use totem with fluid-soundfont-gm. For OS X users, we try to use the simple open or timidity, and for windows users you should install timidity.

DataSounds comes with default pre settings of get_music function, which may be changed accordingly the user prefferences. The help function displays:

Setting parameters

Parameters can be changed if you want to use DataSounds to differentiate two or more series. This usage requires the difference of instruments and also the number of octaves of each series. For example:

This example shows how to use different instruments for each series (e.g. Acoustic Grand Piano for ts_a and Rock Organ for ts_b.

The usage of octaves can better perform distinction between values. We can correlate this parameter as colorbars, if you have a colorbar with 7 colors to represent more than 7 distinct values, your display may be masking some results. Same logical procedure can be adopted here.
