== Data formats ==
Within the AMBIsense solution, measurements of the 1/3 octaveband spectrum are performed. The results of these measurements can be exported in multiple formats:

* as a self explanatory CSV-table
* as either of the following very simple, yet efficient propriatairy binary formats:
** phen1 file: a very restrictive format, making small datasets available as small as possible, while maintaining random accessibility on row level
** as an [[ASAsense Binary Table (ABT) format|ABT]] file: fast and efficient random access (both on row and column level), binary table format
