如何使用playsound模块停止音频？

Question

如何在Python代码中通过playaudio模块停止音频播放？ 我演奏过音乐，但我不能停止那音乐。我怎样才能阻止它

playsound.playsound("name_of_file")

Answer 1

Playsound是一个播放声音的单一功能模块，除此之外没有其他功能。这似乎意味着它也不会停止播放声音。根据他们自己的文件：

The playsound module contains only one thing - the function (also named) playsound.

就个人而言，我喜欢使用pyaudio。以下代码改编自示例here。该代码播放音频，并将空格键设置为暂停/播放按钮

import pyaudio
import wave
import time
from pynput import keyboard

paused = False    # global to track if the audio is paused
def on_press(key):
    global paused
    print (key)
    if key == keyboard.Key.space:
        if stream.is_stopped():     # time to play audio
            print ('play pressed')
            stream.start_stream()
            paused = False
            return False
        elif stream.is_active():   # time to pause audio
            print ('pause pressed')
            stream.stop_stream()
            paused = True
            return False
    return False


# you audio here
wf = wave.open('audio\\songs\\And_Your_Bird_Can_Sing_mp3_2_wav.wav', 'rb')

# instantiate PyAudio
p = pyaudio.PyAudio()

# define callback
def callback(in_data, frame_count, time_info, status):
    data = wf.readframes(frame_count)
    return (data, pyaudio.paContinue)

# open stream using callback
stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
                channels=wf.getnchannels(),
                rate=wf.getframerate(),
                output=True,
                stream_callback=callback)

# start the stream
stream.start_stream()

while stream.is_active() or paused==True:
    with keyboard.Listener(on_press=on_press) as listener:
        listener.join()
    time.sleep(0.1)

# stop stream
stream.stop_stream()
stream.close()
wf.close()

# close PyAudio
p.terminate()

您可以使用多处理模块将声音作为后台进程播放，然后随时终止：

import multiprocessing
from playsound import playsound

p = multiprocessing.Process(target=playsound, args=("file.mp3",))
p.start()
input("press ENTER to stop playback")
p.terminate()

在windows上尝试： import winsound

winsound.PlaySound(r'C:\sound.wav', winsound.SND_ASYNC)

停止播放：

winsound.PlaySound(None, winsound.SND_PURGE)
