This is a sound sample used in my DIY e-reader app. The original sample was taken from: <a href="https://www.freesound.org/people/Corsica_S/sounds/336997/download/336997__corsica-s__boo-01.wav" rel="nofollow">https://www.freesound.org/people/Corsica_S/sounds/336997/download/336997__corsica-s__boo-01.wav</a> I eq'ed it and MP3 encoded it.
