How to execute several fonctions at the same time - yoyo - Dec-16-2020 hello, I have a python project where I should use this fonction to make musics. from simpleaudio import * import numpy as np def sound(freq, duration): sample_rate = 44100 t = np.linspace(0, duration, int(duration * sample_rate), False) tone = np.sin(freq * t * 2 * np.pi) tone *= 8388607 / np.max(np.abs(tone)) tone = tone.astype(np.int32) i = 0 byte_array = [] for b in tone.tobytes(): if i % 4 != 3: byte_array.append(b) i += 1 audio = bytearray(byte_array) play_obj = play_buffer(audio, 1, 3, sample_rate) play_obj.wait_done()I want to integrate this function in a Tkinter window to play music while displaying notes on the screen. I know how to display the note but my function sound block my Tkinter window. So how should I call my function sound to execute the two at the same time ? RE: How to execute several fonctions at the same time - Larz60+ - Dec-16-2020 I think you want to use multiprocessing (not threading) here. see: https://docs.python.org/3/library/multiprocessing.html RE: How to execute several fonctions at the same time - buran - Dec-16-2020 https://python-forum.io/Thread-Tkinter-How-to-deal-with-code-that-blocks-the-mainloop-freezing-the-gui RE: How to execute several fonctions at the same time - yoyo - Dec-22-2020 Thanks for your answers, I read those two links, but I'm a beginner in python so I still don't understand how those two methods works and how I can use it for my program. Can someone explain it to me more simply? |
