A Daily CSV for all Children, all dates is a master record of all recording files for all active children in your LENA database.  It should be exported prior to performing any data merge, move, or cleanup.  

Note: The resulting export will contain data for active child records only.  If you are preparing for a supported database merge or reprocessing, first check to see whether you have any inactive child records.  If you do, please contact LENA Support for next steps.

The CSV export presents the LENA Core Report, AVA, and Developmental Snapshot measures in tabular format, including:

• Adult Words - actual counts, plus projected counts and percentiles where applicable (i.e., at the Daily or Monthly resolution for files containing >10 hours within a calendar day)
• Conversational Turns - actual counts, plus projected counts and percentiles where applicable
• Child Vocalizations - actual counts, plus projected counts and percentiles where applicable
• Audio Environment summary information (percent “Meaningful,” “Distant,” “TV & Electronic Sounds,”, “Silence & Background,” and “Noise”)
• AVA Report Data - standard scores and percentiles, daily and averaged where applicable
• Snapshot Report Data - developmental age, standard score, and percentile

Tip: The following instructions can be adapted to meet other export goals.  Simply adjust the time resolution, select a specific date or date range, select a specific child or children, and/or deselect any of the specific reports.
