key2audio

key2audio™ is the successful predecessor of key2audioXS™ with more than 30 million discs protected worldwide. A hidden signature applied to the disc during glass master manufacturing prevents playback on PC/MAC and thereby prevents copying or track ripping.

key2audio™ products are highly reliable and compatible because the audio part fully complies with the Red Book standard - not a single bit is changed in the audio data stream. In other words, no uncorrectable errors are used to protect the audio data. This gives the highest audio quality for your protected music.

A protected CD still achieves a maximum recording time of 77 minutes and supports full ISRC, UPC and CD-Text capabilities.
