Audio input
 | 
 | 
| An extensive documentation system can store sound input,
like cardiac and fluid sounds. For audio input you will also need the following
hardware:   | 
 | 
  | 
Sound card
 The sound card consists of an analog-digital converter to record the
analogous audio input digitally, and a digital-analog converter to play
back recorded sounds.  | 
 
 
 | 
  | 
Microphone
 You can use a standard microphone, but depending on your specific medical
application, it is recommended that special equipment be used to get optimal
recordings.  | 
 
 
 | 
  | 
Speakers
 It is up to the user which kind of speakers to use. I recommend screens
with integrated speakers.  | 
 
 
 | 
 | 
| As soon as these requirements are met, your documentation
system only has to handle your data.  |
