Record any sound during a picked duration. It is veeery lightweigh: I did a recording during 2 hours and half and the final file is only 27 Mb big, and it used even less battery (less than 2%).
You can also stop the recording by deleting the notification.
Technical info: the file is a .3gp file, located in your Download directory.
