Renesas Technology Corp. has launched the WMA Pro LBR decode middleware that supports WMA 10 Professional M0 profile with enhanced Low Bit Rate (LBR) specification, enabling to decode LBR streaming data that is smaller size at the same audio quality, or better audio quality at the same bit rate. Intended for use in the development of applications for handsets employing the SuperH-Mobile (SH-Mobile) application processor, the software supports both WMA Standard and WMA Professional M0 profile. The middleware also works on SuperH processor for car/home audio system.

The WMA standard is one of the most widely used audio formats on devices such as PCs, cell phones, portable audio players, car audio systems and home audio systems. Moreover, the WMA Pro LBR decode middleware is certified of Microsoft's Windows Media Technology, so developers can use it with confidence.

The solution also offers easy program development in short period. WMA format data is stored in an ASF file format developed by Microsoft. It is necessary to extract the WMA format data from the ASF file to process it.

WMA Pro LBR decode middleware has an API that implements all necessary operations, including accepting ASF files as input, extracting WMA format data and decoding it. The developer can realise WMA audio player functionality simply by inserting calls to this API in a program. This allows applications to be developed in short period.

Moreover, WMA Pro LBR Decode Middleware includes an API that accepts WMA format data as input and decodes it. This makes it possible to develop applications that can process both A/V data. An example would be a player application that decodes and plays WMA and Windows Media Video data simultaneously.

Using with WMA/ Digital Rights Management (DRM) Decode Middleware from Renesas, WMA Pro LBR Decode Middleware enables to support for functions of Windows Media DRM 10. The processing necessary to play copyright protected WMA format audio data can be accomplished simply by inserting commands that call an API function for decryption.

The new WMA Pro LBR Decode Middleware will be available from August 2007 in Japan.
