Renesas Technology Europe has announced WMA Pro LBR Decode Middleware which will be available from August 2007. Intended for use in the development of applications for mobile phone handsets employing the SH-Mobile application processor, the software supports the M0 profile of the Windows Media Audio (WMA) 10 Professional audio compression technology developed by Microsoft Corporation. WMA Pro LBR Decode Middleware includes support for WMA 10 Professional M0 profile and it also supports the WMA 10 Professional M0 profile with enhanced Low Bit Rate (LBR) specification. With this function, WMA Pro LBR Decode Middleware enables the decoding of LBR streaming data that is a smaller size at the same audio quality, or better audio quality at the same bit rate. In addition, WMA Pro LBR Decode Middleware is certified for use with Microsoft’s Windows Media Technology, so developers can use it with confidence.

WMA Pro LBR Decode Middleware offers simplified support for copyright protected data in WMA format. Using with WMA/DRM (Digital Rights Management) Decode Middleware from Renesas Technology, 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 product offers easy program development in a short time period. WMA format data is stored in an ASF (Advanced Systems Format) file format developed by Microsoft. It is necessary to extract the WMA format data from the ASF file in order to process it. WMA Pro LBR Decode Middleware has an API (Application Programming Interface) 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.

In addition, 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 audio and video data. An example would be a player application that decodes and plays WMA and Windows Media® Video data simultaneously.

Typical applications are portable player applications supporting playback of Windows Media® Audio data on mobile phone systems employing SH-Mobile, and on systems employing SuperH processors.
