WMA Decoder
Windows Media Audio, popularly known as WMA, is the audio coding standard defined by Microsoft. This document gives the details of features and performance (MHz and memory ) of the WMA decoder on SNE.
WMA V9 defines various codec types known as 1) WMA Standard 2) WMA Professional 3) WMA Voice and 4) WMA Lossless. WMA V9 also defines four device profiles for WMA Standard codec known as
1) WMA L1: Only 44.1 KHz is supported upto 160 kbps.
2) WMA L2: Includes WMA L1, plus upto 48 KHz sampling rate at 256 kbps.
3) WMA L3: Full implementation. Includes WMA L1 and WMA L2 plus bitrates of 192-320 kbps for both 44.1 and 48 KHz sampling rates.
4) WMA L: PC only profile intended to showcase full codec capabilities and is not intended for devices.
1) WMA L1: Only 44.1 KHz is supported upto 160 kbps.
2) WMA L2: Includes WMA L1, plus upto 48 KHz sampling rate at 256 kbps.
3) WMA L3: Full implementation. Includes WMA L1 and WMA L2 plus bitrates of 192-320 kbps for both 44.1 and 48 KHz sampling rates.
4) WMA L: PC only profile intended to showcase full codec capabilities and is not intended for devices.

Case studies
Developing an Asynchronous Sample Rate Converter
Designing an Asynchronous Sample Rate converter that offers high THD and low ripple across a range of frequencies is no mean achievement. We not only designed the ASRC but implemented it with low MHz on a fixed point processor.

Video codecs on a multi-core highly-parallel custom core
We worked with SiliconHive (now part of Intel) to develop High Definition video codecs that are designed to run optimally on a multi-core environment. Our contribution also included efficient coding for a VLIW core and algorithmic innovations to address memory bandwidth constraints.
