D-Lab Audio is the right choice to analyze and understand what subjects are saying. Simply connect up to 16 microphones to D-Lab and all microphones will be recorded synchronously as separate audio channels. D-Lab Audio is often used in Think Aloud Studies, Cognitive Walkthroughs or Focus Groups.

Prepare your study by defining what audio source you want to record. Listen in realtime what subjects are saying and replay all recorded audio channels either all together or selected ones to analyze and understand the background noise or what subjects said.


– All channels are stored in separate audio files
– Playback for selectable channels
– Audio can be visualized in amplitude charts
