pygame mixer Sound无法同时播放太多声音

Question

我的程序想要同时播放音频，但是pygame.mixer.Sound无法同时播放太多声音。我经常按着按着就没声音了。当然，这也有可能是别的问题，如何解决呢？

这是__init__.py

mport keyboard
import threading
import time

import values

is_played_chord = False
chord_keys = {'a'}

def play_chord(bpm_time):
    global is_played_chord
    while True:
        notes = values.chordkeys.get(frozenset(chord_keys), ())
        is_played_chord = True
        for note in notes:
            values.LEFT_NOTES[note].play()
        time.sleep(bpm_time)
        for note in notes:
            values.LEFT_NOTES[note].stop()

def ask_bpm():
    try:
        return int(input("Enter your BPM: "))
    except ValueError:
        print("Please enter a number")
        return ask_bpm()
    
def on_press(key):
    global is_played_chord
    global chord_keys
    if key.name in values.RIGHT_HAND_KEYS:
        #这儿的判断是正确执行的，没有遗漏
        note = values.RIGHT_NOTES[key.name]
        #这里的stop是被迫添加的，有一点用，但不多
        note.stop()
        note.play()
    elif key.name in values.LEFT_HAND_KEYS:
        if is_played_chord:
            chord_keys = set()
            is_played_chord = False
        chord_keys.add(key.name)
    else:
        print("Unknown key {0} pressed".format(key.name))

def on_release(key):
    if key.name in values.RIGHT_HAND_KEYS:
        values.RIGHT_NOTES[key.name].stop()

def main():
    bpm_time = 60 / ask_bpm()
    keyboard.on_press(on_press)
    keyboard.on_release(on_release)
    threading.Thread(target=play_chord, args=(bpm_time,)).start()
    keyboard.wait()

if __name__ == '__main__':
    main()

这是value.py

from typing import Dict, FrozenSet, Tuple
from pygame import mixer

mixer.init()
LEFT_HAND_KEYS = {'a','s','d','f','z','x','v','q','w','e','r','1','2','3'}
RIGHT_HAND_KEYS = {'g','h','j','k','l','t','y','u','i','o','p','b','n',',','.','5','6','7','9','0'}
LEFT_NOTES = {key: mixer.Sound(f"piano/left/{key}.wav") for key in (
   'c0','d0','e0','f0','g0','a0','b0',
   'C','D','E','F','G','A','B',
   '#c0','#d0','#f0','#g0','#a0',
   '#C','#D','#F','#G','#A',
   )
}
RIGHT_NOTES = {key: mixer.Sound(f"piano/right/{key}.wav") for key in RIGHT_HAND_KEYS}

chordkeys:Dict[FrozenSet[str],Tuple[str]] = {
   frozenset({'a',}) : ("C","G","c0","e0"),
   frozenset({'s',}) : ("D","A","d0","#f0"),
   frozenset({'d',}) : ("E","B","e0","#g0"),
   frozenset({'f',}) : ("F","C","f0","a0"),
   frozenset({'q',}) : ("G","B","d0","g0"),
   frozenset({'w',}) : ("A","c0","e0","a0"),
   frozenset({'e',}) : ("B","#d0","#f0","b0"),
   frozenset({'r',}) : ("C","G","c0","e0"),
}

以下回答参考GPT，请查看是否可以解决你的问题：
您遇到的问题可能是由于pygame.mixer.Sound无法同时播放太多声音导致的。这是因为在pygame.mixer.Sound中，每个声音都需要独立的声道，如果同时播放太多声音，声道可能不足，导致一些声音被静音或丢失。

为了解决这个问题，可以考虑使用pygame.mixer.music模块来实现同时播放多个声音。相比于pygame.mixer.Sound，pygame.mixer.music能够更好地处理同时播放多个声音的情况。

以下是对您提供的代码进行修改的示例：

import keyboard
import threading
import time
import pygame.mixer

import values

is_played_chord = False
chord_keys = {'a'}

def play_chord(bpm_time):
    global is_played_chord
    while True:
        notes = values.chordkeys.get(frozenset(chord_keys), ())
        is_played_chord = True
        for note in notes:
            pygame.mixer.music.load(values.LEFT_NOTES[note])
            pygame.mixer.music.play()
        time.sleep(bpm_time)
        pygame.mixer.music.stop()

def ask_bpm():
    try:
        return int(input("Enter your BPM: "))
    except ValueError:
        print("Please enter a number")
        return ask_bpm()

def on_press(key):
    global is_played_chord
    global chord_keys
    if key.name in values.RIGHT_HAND_KEYS:
        note = values.RIGHT_NOTES[key.name]
        note.stop()
        note.play()
    elif key.name in values.LEFT_HAND_KEYS:
        if is_played_chord:
            chord_keys = set()
            is_played_chord = False
        chord_keys.add(key.name)
    else:
        print("Unknown key {0} pressed".format(key.name))

def on_release(key):
    if key.name in values.RIGHT_HAND_KEYS:
        values.RIGHT_NOTES[key.name].stop()

def main():
    bpm_time = 60 / ask_bpm()
    keyboard.on_press(on_press)
    keyboard.on_release(on_release)
    threading.Thread(target=play_chord, args=(bpm_time,)).start()
    keyboard.wait()

if __name__ == '__main__':
    pygame.mixer.init()
    main()

在修改后的代码中，我添加了pygame.mixer.init()来初始化音频模块，并且使用了pygame.mixer.music来同时播放多个声音。注意，在使用pygame.mixer.music时，需要确保音频文件的路径是正确的。

请注意，由于我无法运行完整的代码并测试它，在实际运行中可能会遇到其他问题。如果您仍然遇到困难，请提供更多的细节和错误信息，以便我能够更好地帮助您解决问题。
