SD-Audio

SD-Audio provides the codecs and file format necessary to transfer, store or download audio files on mobile phones and other devices.

The data is secured by CPRM, the built in copyright protection function of SD standards. Unlike other flash cards, all SD memory cards and SDHC memory cards use CPRM so users do not need to search for special cards.

SD-Audio supports the widely used AAC, HE-AAC, WMA and MP3 formats.
