The WMA Encoder package for the Xtensa
HiFi 2 Audio Engine implements 24-bit encoding of high-, mid-, and low-rate WMA data streams as well as the encoding of ASF (Advanced Streaming Format) data streams. The encoder 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 encoder into an SOC without the need for additional optimizations or software development. The same Xtensa HiFi 2 Audio Engine is used for other Tensilica audio codecs, enabling the development of highly optimized multi-standard audio SOC designs.
