Audio Module examples 

Sound Recorder Example

import appuifw, e32

# import the audio module

import audio

#This defines a name of the file to be the sound file, incl. its full path

filename = 'e:\\chime.wav'

#This defines the recording part:

def recording():

 global S

 # open the sound file to be ready for recording and set an instance (S) of it

 S=audio.Sound.open(filename)

 # do the recording (has to be stopped by closing() function below)

 S.record()

 print "Recording .Select Stop to end"

# define the playing part:

def playing():

 global S

 try:

 # open the sound file to be ready for playing by setting an instance (S) of it

 S=audio.Sound.open(filename)

 # play the sound file

 S.play()

 print "Playing"

 except:

 print "Record a sound first!"

# stopping of recording / playing and closing of the sound file

def closing():

 global S

 S.stop()

 S.close()

 print "Stopped"

def quit():

 script_lock.signal()

 appuifw.app.set_exit()

# define the application menu

appuifw.app.menu = [(u"play", playing),

 (u"record", recording),

 (u"stop", closing)]

appuifw.app.title = u"Sound recorder"

appuifw.app.exit_key_handler = quit

script_lock = e32.Ao_lock()

script_lock.wait()

Midi Player Example

import appuifw

import e32

import audio

def playsound1():

 S = audio.Sound.open("E:\\sound1.mid")

 S.play()

 menu()

def playsound2():

 S = audio.Sound.open("E:\\sound2.mid")

 S.play()

 menu()

def exit_key_handler():

 appuifw.app.set_exit()

def quit():

 appuifw.app.set_exit()

L = [u"sound 1", u"sound 2", u"exit"]

def menu():

 index = appuifw.popup_menu(L,u'select')

 if index == 0:

 playsound1()

 if index == 1:

 playsound2()

 if index == 2:

 quit()

appuifw.app.title = u"Midi player"

appuifw.app.exit_key_handler = exit_key_handler

menu()
