Im working on an interactive piece using an alternate form of the doppler effect and I would appreciate some help in making it play sound. Thank you import wave class SoundFile: def __init__(self, signal,lab=''): self.file = wave.open('./test' + lab + '.wav', 'wb') self.signal = signal self.sr = 44100 def write(self): self.file.setparams((1, 2, self.sr, 44100*4, 'NONE', 'noncompressed')) self.file.writeframes(self.signal) self.file.close() mypi = float(pi) from math import sin var('x') @interact def sinsound(f = slider(16,16000,1,5120)): v = 340.29 html('$y = f*(((v)+ tan(x))/((v)+sin(x))))$') y = f*((v+tan(x))/(v+sin(x))) hz1 = y s2 = [sin(hz1*x*mypi*2) for x in srange(0,4,1/44100.0)] s2m = max(s2) s2f = [16384*x/s2m for x in s2] s2str = ''.join(wave.struct.pack('h',x) for x in s2f) lab="%1.2f"%float(f) f = SoundFile(s2str,lab=lab) f.write() pnum = 1500+int(500/f) show(list_plot(s2[0:pnum],plotjoined=True)) html('')
