Instructions You will need to download ALL 4 Zip fils then put all the audio files in the Protools session folder.

You do not have to use Protools but you will not have the playback levels calibrated.

Not a total must but enough for an OK subjective test.

So to add to the many discussions I decided to test all of my convertors I use

1. -Apogee Rosetta 800
   

2. -Apogee AD-16X
   

3. -Lynx Aurora 8
   

4. -Digidesign 192                                                                                                               •The Test
   

5. -All Convertors were clocked @ 44.1 Sample Rate with an Apogee Big Ben
   

6. -All Convertors were direct connected with Protools HD version 7.4.2
   

7. -The sessions can be open with Protools LE
   

8. - did a manual phase align later in the session - FWIW they do not phase cancel. So with that said there are audible differences in the files. The original files files are included in the session
   

9. -If you look at the comments you will see the calibration levels and the gain that was done on each file before recording some convertors had different calibration levels so I calibrated the output of each track. So the trim plug-in is important to keep it on.
   

10. -All of the tracks were recorded analog so this is an Analog to Digital Conversion test
    

11. -Feel free to leave a comment
    

12. -Thanks for listening
