audio - How can I generate a note or chord in python? -


can point me library generating notes , chords in python 2.7? have looked @ pythoninfowiki without lot of luck, pyaudio crashes , nothing else seems generate tones.

i don't know if help, here's code synthetizes complex sound based on gives frequencies , amplitudes:

import math import wave import struct  def synthcomplex(freq=[440],coef=[1], datasize=10000, fname="test.wav"):     frate = 44100.00       amp=8000.0      sine_list=[]     x in range(datasize):         samp = 0         k in range(len(freq)):             samp = samp + coef[k] * math.sin(2*math.pi*freq[k]*(x/frate))         sine_list.append(samp)     wav_file=wave.open(fname,"w")     nchannels = 1     sampwidth = 2     framerate = int(frate)     nframes=datasize     comptype= "none"     compname= "not compressed"     wav_file.setparams((nchannels, sampwidth, framerate, nframes, comptype, compname))     s in sine_list:         wav_file.writeframes(struct.pack('h', int(s*amp/2)))     wav_file.close()  synthcomplex([440,880,1200], [0.4,0.3,0.1], 30000, "tone.wav") 

that's code i'm using generate notes , chords in python. shold have frequencies list first parameter, amplitude list (same size first) , number of samples , name of file. generate wav file given combination.
