• Separator: semicolon ;
• one row per minute (interval)
• first column Timestamp: end of the interval in ISO 8601 format with time zone, for example 2026-07-12T22:15:00.0000000+02:00
• then one column per value of the value profile, in its order, with name and unit in the header
• values in dB with one decimal place, including offset
• decimal separator according to the user interface language

Excluded time ranges, comments and events are not included in the CSV.

.splsense

A .splsense file contains a whole measurement from SPL Sense with all recordings, signed intervals, events and settings. It is used for backup and for transfer to another computer (Import and export).

The format is internal and may change with new versions. For evaluation in your own software, use the CSV export and the SPL Sense API.
