The Lung Sound Recorder allows users to record lung sounds from eleven different recording locations on the body. These sounds are saved on the phone and can be listened to by the user or analyzed using lung sound algorithms.

This app enables the following capabilities:
* Telehealth - Recorded sounds can be transmitted to physicians in remote locations.
* Longitudinal tracking of a patient - Sound files can be saved as part of patient record allowing a physician to assess health by comparing lung sounds across visits.
* Canonical sound databases - Typical sound files of each type can be collected and can be directly compared to new patient recordings to improve lung sound recognition.
* Development of training databases - Large numbers of lung sounds can be easily collected and compiled into a training database for students and residents.

To make recordings you will need an electronic stethoscope. A tutorial on how to build your own is available at openlungsounds.com.
