py_s60 1.1.3 provide audio module which allow you to record sound.
import e32, audio
s = audio.Sound.open('C:\\test.amr')
s.record() # start recording
e32.ao_sleep(5) # do if for 5 seconds
s.stop() # stop recording
# the file is now created, ready to be played
Using this code, I can record sound longer than
the 1 minute limit by Nokia's 'Recorder' program.
It can record in 'wav', 'amr','au'.
I can't play the file recorded with 'wav', though.
It seems 6600 has the problem with uncompressed 16-bit wave.
(It can play other wave files fine.)
