====Recording====

Some electronic stethoscopes feature direct audio output that can be used with an external recording device, such as a [[notebook computer|laptop]] or [[MP3]] recorder. The same connection can be used to listen to the previously recorded [[auscultation]] through the stethoscope headphones, allowing for more detailed study for general research as well as evaluation and consultation regarding a particular patient's condition and [[telemedicine]], or remote diagnosis.<ref>Palaniappan R, Sundaraj K, Ahamed NU, Arjunan A, Sundaraj S.

Transforming Healthcare Through Digital Patient Engagement'', Himss Books, 2012 {{ISBN|1938904397}}.</ref>  At least one uses the phone's own microphone to amplify sound, produce a visualization, and e-mail the results.  These apps may be used for training purposes or as novelties, but have not yet gained acceptance for professional medical use.<ref>William Hanson, ''Smart Medicine: How the Changing Role of Doctors Will Revolutionize Health Care'', [https://books.google.com/books?id=FKlKjUgduP0C&pg=PA22 pp. 20–22], Macmillan, 2011 {{ISBN|0230120938}}.</ref>
