python使用wxPython打開并播放wav文件的方法

這篇文章主要介紹了python使用wxPython打開并播放wav文件的方法,涉及Python操作音頻文件的相關技巧,需要的朋友可以參考下

本文實例講述了python使用wxPython打開并播放wav文件的方法。分享給大家供大家參考。具體實現(xiàn)方法如下：

''' wx_lib_filebrowsebutton_sound.py

select a sound file and play it

wx.lib.filebrowsebutton.FileBrowseButton(parent, labelText, fileMask)

(combines wx.TextCtrl and wxFileDialog widgets)

wx.Sound(fileName, isResource=False)

tested with Python27 and wxPython291 by vegaseat 25jul2013

'''

import wx

import wx.lib.filebrowsebutton

class MyFrame(wx.Frame):

def __init__(self, parent, mytitle, mysize):

wx.Frame.__init__(self, parent, wx.ID_ANY, mytitle,

size=mysize)

self.SetBackgroundColour("green")

panel = wx.Panel(self)

# mask file browser to look for .wav sound files

self.fbb = wx.lib.filebrowsebutton.FileBrowseButton(panel,

labelText="Select a WAVE file:", fileMask="*.wav")

self.play_button = wx.Button(panel, wx.ID_ANY, ">> Play")

self.play_button.Bind(wx.EVT_BUTTON, self.onPlay)

# setup the layout with sizers

hsizer = wx.BoxSizer(wx.HORIZONTAL)

hsizer.Add(self.fbb, 1, wx.ALIGN_CENTER_VERTICAL)

hsizer.Add(self.play_button, 0, wx.ALIGN_CENTER_VERTICAL)

# create a border space

border = wx.BoxSizer(wx.VERTICAL)

border.Add(hsizer, 0, wx.EXPAND|wx.ALL, 10)

panel.SetSizer(border)

def onPlay(self, evt):

filename = self.fbb.GetValue()

self.sound = wx.Sound(filename)

# error handling ...

if self.sound.IsOk():

self.sound.Play(wx.SOUND_ASYNC)

else:

wx.MessageBox("Missing or invalid sound file", "Error")

app = wx.App(0)

# create a MyFrame instance and show the frame

mytitle = "wx.lib.filebrowsebutton and wx.Sound"

width = 600

height = 90

MyFrame(None, mytitle, (width, height)).Show()

app.MainLoop()

希望本文所述對大家的Python程序設計有所幫助。
