Question

我正在尝试在python中创建一个图形均衡器。一切进展顺利，但我无法实时运行音频。我设计了5个滑块，代表每个频段（总共5个频段）。每次我操纵这些滑块时，scikits音频播放都会重新计算。这是我的代码，所以你可以看到我更详细的信息

均衡器功能：

from Tkinter import *
import tkFileDialog
import threading
from Equalizer import processAudio

# GUI assosiated Functions
filepath = ''

def choosefile():
    try:
        global filepath
        filepath = tkFileDialog.askopenfilename(filetypes=[('Audio Files', '*.wav')])
        filenamelabel.config(text=filepath)
    except ValueError:
        pass


def getSliderValues():
    sliderVector = []
    sliderVector.append(Value45hz.get())
    sliderVector.append(Value700hz.get())
    sliderVector.append(Value2khz.get())
    sliderVector.append(Value8khz.get())
    sliderVector.append(Value15khz.get())
    if filepath:
        audioThread = threading.Thread(target=processAudio, args=(filepath, sliderVector[0], sliderVector[1], sliderVector[2], sliderVector[3], sliderVector[4]))
        audioThread.start()
    test45hzslider.after(500, getSliderValues)
