AD only

AD only is a measuring method, in which an acoustic incident (e.g. noise, sound, music...) is being recorded.

In the Measurement setup the basic settings for the measurement are to be undertaken.

In the Processing section the recording can be processed.

OK starts measuring, Cancel quits the operation.

The screenshot shows a simple AD measurement on one channel. After measuring the level meter at the bottom right displays the maximum recording level received. The bar turns red on overload, yellow up to -3dBFs, green between -3 and -20dBFs, and blue for the remaining level range down to -60dBFs.
