Sleep talking software
 

Last night I thought I would try this phone software which records when a noice or a voice is picked up. Anyway I forgot about it and left it in a closed drawer and went to work. Anyway tonight I have listened to it and this afternoon It picked up a bang and the draw it was kept in was opened and closed. Also heard a faint female voice but it's so quiet I can't make it out. Door was locked and no one at home. Will keep setting it up this week.
