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/harrybates01/sounds/254366/download/254366__harrybates01__heartbeat-fast.wav" rel="nofollow">https://www.freesound.org/people/harrybates01/sounds/254366/download/254366__harrybates01__heartbeat-fast.wav</a> I eq'ed it and MP3 encoded it.
