Hướng dẫn python play wav file - python chơi tệp wav

Tôi có một while loop cho máy ảnh của tôi (với OpenCV) để chụp ảnh khi có thứ gì đó di chuyển. Tôi cũng muốn gọi một chức năng để phát một âm thanh là tốt. Nhưng khi tôi gọi và chơi nó, nó sẽ ngừng lặp lại cho thời gian thực hiện đó. Tôi đã thử ThreadPoolExecutor nhưng không biết làm thế nào tôi có thể trộn nó với mã của mình, bởi vì tôi không chuyển bất cứ thứ gì cho chức năng. Chỉ gọi nó từ Loop. BTW. Tôi muốn có thể chơi nó nhiều lần (nhiều lần thực hiện trong thời gian thực thi) nếu nhiều something trong mã xuất hiện từ Loop

tập lệnh camera

from play_it import alert

while True:
    #do something in cv2
    if "something":
        alert() # Here it slowing the loop

và tập lệnh

from playsound import playsound
import concurrent.futures

def alert():
    playsound('ss.mp3')


def PlayIt():
    with concurrent.futures.ThreadPoolExecutor() as exe:
        exe.map(alert, ???) # not sure what to insert here

from playsound import playsound
import concurrent.futures

def alert():
    playsound('ss.mp3')


def PlayIt():
    with concurrent.futures.ThreadPoolExecutor() as exe:
        exe.map(alert, ???) # not sure what to insert here

Trong bài viết này, chúng ta sẽ thấy cách phát âm thanh trong Python bằng cách sử dụng một số thư viện âm thanh phổ biến nhất. Chúng tôi sẽ tìm hiểu về các phương pháp khác nhau để phát âm thanh.

Phương pháp 1: Sử dụng mô -đun chơiUsing playsound module

Chạy lệnh sau để cài đặt các gói:

pip install playsound

• Mô -đun chơi chỉ chứa một hàm duy nhất có tên Playsound ().playsound().
• Nó yêu cầu một đối số: đường dẫn đến tệp với âm thanh chúng ta phải phát. Nó có thể là một tập tin cục bộ, hoặc một URL.
• Có một đối số thứ hai tùy chọn, khối, được đặt thành true theo mặc định. Chúng ta có thể đặt nó thành sai để làm cho chức năng chạy không đồng bộ.block, which is set to True by default. We can set it to False for making the function run asynchronously.
• Nó hoạt động với cả tệp WAV và MP3.WAV and MP3 files.

Ví dụ: Đối với định dạng WAVFor WAV format

Python3

from playsound import playsound
import concurrent.futures

def alert():
    playsound('ss.mp3')


def PlayIt():
    with concurrent.futures.ThreadPoolExecutor() as exe:
        exe.map(alert, ???) # not sure what to insert here

from playsound import playsound
import concurrent.futures

def alert():
    playsound('ss.mp3')


def PlayIt():
    with concurrent.futures.ThreadPoolExecutor() as exe:
        exe.map(alert, ???) # not sure what to insert here

from playsound import playsound
import concurrent.futures

def alert():
    playsound('ss.mp3')


def PlayIt():
    with concurrent.futures.ThreadPoolExecutor() as exe:
        exe.map(alert, ???) # not sure what to insert here

from playsound import playsound
import concurrent.futures

def PlayIt():
    with concurrent.futures.ThreadPoolExecutor() as exe:
