Overview

This snippet shows how to record audio in Python.

Preconditions

Valid file formats must be used. Their availability may vary from one device generation to another and they tipically include WAV, AMR, MP3, AAC, RA.

Source code

import e32, audio
 
 
#Open a sound file at the given path
s = audio.Sound.open(u"C:\\sound.amr")
#Start recording
s.record()
#Instantiate a timer
t = e32.Ao_timer()
#Record for 10 seconds, then stop
t.after(10, lambda:s.stop())

Postconditions

Sound is recorded to an audio file at the specified path.

Known issue

Issue with Nokia 6600: Apparently files recorded in WAV format cannot be played. It seems Nokia 6600 has the problem with uncompressed 16-bit wave but it can play other wave files fine.
