用wxPython实现多进程的音频冻结

import wx

class MyApp(wx.App):
    def OnInit(self):
        # 初始化应用程序
        return True

class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        super().__init__(parent, title=title)
        self.InitUI()

    def InitUI(self):
        # 初始化用户界面
        pass

def OnInit(self):
    self.frame = MyFrame(parent=None, title="音频冻结")
    self.frame.Show()
    return True

def InitUI(self):
    panel = wx.Panel(self)

    # 添加音频文件选择按钮
    file_picker = wx.FilePickerCtrl(panel)
    file_picker.Bind(wx.EVT_FILEPICKER_CHANGED, self.OnFileSelected)

    # 添加冻结按钮
    freeze_button = wx.Button(panel, label="冻结")
    freeze_button.Bind(wx.EVT_BUTTON, self.OnFreeze)

    # 添加文本框显示冻结结果
    self.result_text = wx.TextCtrl(panel, style=wx.TE_READONLY)

    # 设置布局
    sizer = wx.BoxSizer(wx.VERTICAL)
    sizer.Add(file_picker, proportion=0, flag=wx.EXPAND|wx.ALL, border=10)
    sizer.Add(freeze_button, proportion=0, flag=wx.EXPAND|wx.ALL, border=10)
    sizer.Add(self.result_text, proportion=1, flag=wx.EXPAND|wx.ALL, border=10)
    panel.SetSizer(sizer)

def OnFileSelected(self, event):
    # 处理音频文件选择事件
    filepath = event.GetPath()
    # TODO: 根据选择的音频文件进行处理

def OnFreeze(self, event):
    # 处理冻结按钮点击事件
    # TODO: 执行音频冻结操作，并将结果显示在self.result_text中
