You can record sound directly in SMART notebook but there is a one minute limit to these recordings. Another option is to use a free software called Audacity.
Audacity is a free download and very easy to use. It is compatible in both Mac and PC platforms. Being compatible makes it easier in many ways to use with your students since you would only have to teach them one program. Note that when you are saving your Audacity sound files you will want to save as an MP3 file. For more detailed tutorials, please check out the links below:
Download Audacity to use at home on your PC or Mac (it is a free program!) *Be sure to also download the “Lame MP3 Encoder.”
