Chapter 13 sound not playing.

sgoshaye commented 3 years ago

When I run this cell:

sound = pygame.sndarray.make_sound(arr)
sound.play()

I get this error:

@sgoshaye try to reshape an arr : size = 44100 arr = np.repeat(arr.reshape(size, 1), 2, axis = 1)

JaHIY commented 4 months ago

You can try the following code:

import numpy as np
import pygame, pygame.sndarray

pygame.mixer.init(frequency=44100, size=-16, channels=1)
arr = np.random.randint(-10000, 10000, size=44100, dtype='int16') #set `dtype` to `int16`
sound = pygame.sndarray.make_sound(arr)
sound.play()
