DDP Player vs Harmony Calipers

The Sonoris DDP Player is an app that reads DDP images to listen to on your Apple device. The industry standard DDP protocol is supported by all major CD and even vinyl pressing plants, and ensures an error free transfer and manufacture of your master. Whether you are an artist that wants to listen to the final DDP master of your new album or you are a studio owner or producer and want a efficient and quick way to have your masters approved, this app is for you. It can load DDPs directly from a Dropbox account, a download link in the clipboard memory or through the iTunes app. Once downloaded you can open the DDP and see any CD text and ISRC codes, track numbering and spacing, exactly as the mastering engineer has meant it. To use it you need one of these: • a serialnumber for the desktop version of the Sonoris DDP Player or DDP Creator. • a key for the (branded) Sonoris DDP Player OEM. Ask your mastering studio.
