在彼此頂部添加諧波ipython

Question

我希望聽到的下一個聲音是所有以前同時播放的諧波的組合，但我無法讓它工作。仍然是ipython的新手，所以仍然在學習如何使用它。

t = arange(0, 0.5, 1/44100) 
fundamental = 440 
mySound = sin(2*pi*t*100) 
for k in range(1,6) : 
    print "Adding harmonic: ", k 
    mySound = concatenate([mySound, (mySound+(sin(2*pi*((2*k)-1)*t*100)/((2*k)-1)))/k]) 
play(mySound) 
plot(mySound[1:1000]) # plot first 1000 samples 

Answer 1

您需要使用此外，不串聯。也就是說，這樣的：

for k in range(1,6) : 
    print "Adding harmonic: ", k 
    mySound += sin(2*pi*((2*k)-1)*t*100)/((2*k)-1)))/k 
    # or mySound = mySound + sin(2*pi*((2*k)-1)*t*100)/((2*k)-1)))/k # is close to the same thing (though less efficient) and more similar to what you had 

級聯會把波形終端到終端的，所以你會聽到他們一個接一個，按順序排列。
