D-Lab Audio
Audio recordings are a suitable method for understanding and analyzing the cognitive processes of your test participants during the test and adding contextual awareness to other data sources. With D-Lab Audio you can record up to 16 microphones synchronously as separate audio channels. D-Lab audio is often used in think-aloud studies, cognitive walkthroughs or focus groups.
Plan-Measure-Analyze
In preparation for your study, you define which audio sources you want to record. During the recording, you can follow what your subjects are saying in real time. Have all or selected recorded audio data played back in order to analyze and understand background noise or the utterances of the test persons.
PRODUCT HIGHLIGHTS
- All channels can be saved as separate audio files
- Play selected channels
- Visualization of the audio signals as amplitude diagrams
- Integrated annotation for precise transcription and analysis
