我有一个简单的节拍器运行,由于某种原因,当它以较低的bpm时就可以了,但是以较高的bpms时则不一致且不稳定。我不知道怎么回事。我想尝试使用一些东西定期运行它。有没有办法做到这一点?
这是我的代码:
class thalam():
def __init__(self,root,e):
self.lag=0.2
self.root=root
self.count=0
self.thread=threading.Thread(target=self.play)
self.thread.daemon=True
self.tempo=60.0/120
self.e=e
self.pause=False
self.tick=open("tick.wav","rb").read()
self.count=0
self.next_call = time.time()
def play(self):
if self.pause:
return
winsound.PlaySound(self.tick,winsound.SND_MEMORY)
self.count+=1
if self.count==990:
self.thread=threading.Thread(target=self.play)
self.thread.daemon=True
self.thread.start()
return
self.next_call+=self.tempo
new=threading.Timer(self.next_call-time.time(),self.play)
new.daemon=True
new.start()
def stop(self):
self.pause=True
winsound.PlaySound(None,winsound.SND_ASYNC)
def start(self):
self.pause=False
def settempo(self,a):
self.tempo=a
class Metronome(Frame):
def __init__(self,root):
Frame.__init__(self,root)
self.first=True
self.root=root
self.e=Entry(self)
self.e.grid(row=0,column=1)
self.e.insert(0,"120")
self.play=Button(self,text="Play",command=self.tick)
self.play.grid(row=1,column=1)
self.l=Button(self,text="<",command=lambda:self.inc("l"))
self.l.grid(row=0,column=0)
self.r=Button(self,text=">",command=lambda:self.inc("r"))
self.r.grid(row=0,column=2)
def tick(self):
self.beat=thalam(root,self.e)
self.beat.thread.start()
self.play.configure(text="Stop",command=self.notick)
def notick(self):
self.play.configure(text="Start",command=self.tick)
self.beat.stop()
def inc(self,a):
