To edit recordings in the Thinklabs Stethoscope App directly on your mobile device, you can use your thumb and forefinger to zoom in and out to display the desired audio segment.
Touch...then touch......to crop the recording to the displayed segment.
If you would like to make additional edits to your recordings, you can send sounds to yourself or to colleagues as an email attachment. You can then access these recording files on your computer and use sound editing software programs like Audacity or Adobe Audition to reduce noise and amplify important pathologies.
We do not provide these programs, but Audacity is free. Just visit www.audacityteam.org and The Thinklabs Audacity Manual for more information. We would be happy to help you through the editing process as well!
