Notetalker Edit can be used on a laptop to record lectures, conversations and meetings using a directional microphone. Where your laptop has a separate 3.5mm jack socket for a microphone this can be plugged directly into the laptop. Where there is only a single socket on your laptop either the device senses the connection of a microphone or you will need the adaptor cable provided to connect your microphone. The adaptor cable can also be used for connection to any smartphone or tablet.
