PIC32 Harmony software decoder framework & Microsoft WMA decoder library

June 26, 2015 // By Graham Prophet
Microchip has announced the PIC32 Harmony Software Decoder Framework and Microsoft Windows Media Audio (WMA) Decoder Library for 32-bit PIC32 microcontroller-based consumer-audio application development within the MPLAB Harmony Integrated Software Framework.

The WMA Decoder Library includes a new modular framework for audio decoders, including support for MP3 and AAC, allowing easier audio application development. Microchip says it will simplify development and increase flexibility of consumer audio products such as audio docks, automotive head units and home audio platforms.

Microchip’s Audio Decoder Framework allows for audio software codecs to be added to a PIC32 design project. Rather than having to rewrite large sections of application code, the framework allows for easier integration into an existing application after the corresponding decoder library has been purchased. The WMA Decoder increases the depth of the library for PIC32 MCU-supported audio decoders, in addition to MP3 and AAC. This increases the range of audio formats that designers can choose to support. The audio decoder framework within the Harmony environment allows designers to add, subtract and switch among various software-based audio decoders. Including a WMA decoder gives developers an even wider set of options and support for audio playback.

The WMA Decoder Library is targeted for low-cost applications in the consumer markets, such as audio docks, home audio receivers and automotive head units. It gives developers added flexibility in decoder options that play back from internal or removable media. The addition of a WMA decoder library further expands the audio application flexibility of PIC32-based designs, building upon existing USB and Bluetooth streaming audio solutions.

The Microsoft WMA Decoder Library is supported by Microchip’s free MPLAB Harmony Integrated Software Framework and PIC32 Bluetooth Audio Development Kit (Part # DV320032, $199.99).

The Microsoft WMA Decoder Library (Part #s SW320015 and SW320025-1HPM, $199.97 and $199.00) is available in two variants.
