Procedural music with PyAudio and NumPy
Combining two of my favorite pastimes, programming and music... This is the hacky "reduced to it's basic components" version of a library I've been working on for generating music and dealing with music theory.
Tweaking the harmonics by changing the shape of the harmonic components and ratios can produce some interesting sounds. This one only uses sine waveforms, but a square / saw generator is trivial with numpy.
It takes a second to generate, so don't turn your volume up too loud in anticipation (it may be loud).
import math
import numpy
import pyaudio
import itertools
from scipy import interpolate
from operator import itemgetter
class Note:
NOTES = ['c','c#','d','d#','e','f','f#','g','g#','a','a#','b']
def __init__(self, note, octave=4):
self.octave = octave
if isinstance(note, int):
self.index = note
self.note = Note.NOTES[note]
elif isinstance(note, st…
