The Dolby Digital Professional SDK supports Dolby's surround sound technology that delivers high-quality digital audio for up to 5.1 discrete channels (L/C/R/LS/RS/LFE). It offers the same features base than the Dolby Digital Consumer SDK, but offers a wider range of parameters for optimizing AC-3 streams, such as more coding modes and a wider range of supported bitrates. It is the sound for DVDs worldwide, found in DVD players, broadcasted HDTV channels, IPTV solutions, etc. The AC-3 standard is based on the ATSC A52 Revision B specification.
For Windows, Mac OS X and Linux, the codec SDK (Software Development Kit) consists of a Low Level API as well as DirectShow filters for decoding and encoding AC-3 streams. The decoder filter can be used by any DirectShow® application (e.g. Windows® Media Player).
Dolby Digital Professional is available as 32-bit and 64-bit for Windows and Linux. A Mac OS X version is currently only available as 32-bit version (64-bit will follow soon).
Please note that you have to be a Dolby licensee, i.e. you have to be registered at Dolby, in order to evaluate the MainConcept Dolby® Digital Consumer SDK. Otherwise, we cannot provide you with an SDK for evaluation.
