The DAE quality test comprises two partial measurements. The DAE quality test results are displayed in the DAE Quality area.
First, audio areas from three different points on the disc are read and stored on the hard drive. The same areas are read again and compared with the buffered data. The DAE quality is awarded a value between 0 and 10 (perfect quality, no differences) depending on the number of differences counted. The determined value is shown on the display panel.
Next, Nero DiscSpeed checks if the optical drive supports accurate streaming. If the Accurate stream check box is enabled, desired audio files can be precisely located on a disc whenever necessary.

 

 
 
If your optical drive performs poorly in the test, we recommend that you also enable a verification feature when ripping CD’s.
