Tensilica’s WMA 10 Pro Decoder Application Package
The Windows Media Audio 10 Professional (WMA 10 Pro) decoder is the most flexible Windows Media audio codec available - supporting profiles that include everything from full-resolution 24-bit/96 kHz audio in stereo, 5.1 channel, or even 7.1 channel surround sound, to highly efficient mobile capabilities at 24 Kbps to 96 Kbps for stereo, and 128 Kbps to 256 Kbps for 5.1-channel sound. WMA 10 Pro offers incredible quality for consumers using high-fidelity hardware and 5.1 channel surround sound-equipped computers -- and for consumers playing audio content on their mobile devices. WMA 10 Pro supports streaming, progressive download, or download-and-play delivery at 128 to 768 Kbps.
The WMA 10 Pro Decoder package for the Xtensa HiFi Audio DSPs implements 24-bit decoding of M0-M3 profile WMA data streams as well as the decoding of ASF (Advanced Streaming Format) data streams. It is fully compliant with Microsoft's WMA test specifications. The decoder is a fixed-point implementation written in C and available in either object or source code. Included documentation describes how to incorporate the decoder into a system. Using this package, system developers can integrate a WMA 10 Pro decoder into an SOC without the need for additional optimizations or software development. The same Xtensa HiFi Audio DSPs are used for other Tensilica audio codecs, enabling the development of highly optimized multi-standard audio SOC designs.
