This can be selected depending on the situation.
When memory is executed in this state, the actual sound data, "WAV data," and the instantaneous sound pressure level at 1-second intervals with a time weight of 10 ms and a frequency weight of Z are created in "CSV data" format. This "CSV data" is used as the playback point when playing back the recorded actual sound data on the "LA-3000 series."

In this state, when you run the memory, in addition to the actual sound data and instantaneous sound pressure level mentioned in ①, various calculated values of the sound pressure level under the conditions selected in Operate Mode will be created in "CSV data" format.

Note: When saving data in "AT/REC" mode, if the measurement is interrupted before the set measurement time elapses, the actual sound data and instantaneous sound pressure level up to the interruption point will be saved, but various calculated values will not be saved, so please be aware.
